If you are looking at this, and want someone to talk you into it knowing what it is, then I will. If you have no clue what this is then I'll explain. Heatsink compound is used between semiconductors and chips and their cooling devices to eliminate microscopic air spaces allowing heat to be transferred away from the device creating it. This was designed for use in computers between the CPU or GPU and its cooling device but is also used for power supplies, audio amplifiers, home theater components, 2 way radios, cellphones, automotive electronics and even can be found in coffee makers and digital clocks and just about any solid state device. A lot of heatsink compounds dry out with age,sometimes before the device is sold while it's still in the warehouse. I've opened many brand new laptops and PC'S and audio amplifiers or PC power supplies to do mods or upgrades and found dried out compound. In power supplies and audio amplifiers this will cause them to overheat and sometimes fail. For CPU's and GPU's this makes them run excessively slow because heat makes them throttle power to save themselves from damage. There is also heat sink "grease" which when it gets really hot has a tendency to run and drip into places it should not. This product was designed by a German company to stay wet and not run, and its simply the best product made for doing this and I have been in the electronic industry since 1976 and have tried literally hundreds of brands. You don't need a lot when you use it correctly and yes it's expensive but it does what its supposed to do and it stays where you put it. When you consider the price of what you may be using it on, it is definitely worth it. Yes for the overclockers there are other options, some pretty pricey gels and metallics, but for the general user or gamer that isn't changing and testing or proofing parts every day then this is what you need and it will last. Honestly if more pc's and phones and other devices were built with this, there would be less service calls as dried out compound is one of the biggest factors in slow sluggish pc's and phones, and premature aging and failure of power supplies and stereo and audio gear.. If a device has a heatsink, this is the best to get, no matter what the device is.

I've purchased this 11g tube of Thermal Grizzly Kryonaut to replace my old tube that had run out so I knew exactly what I'm getting and my expectations are already well managed. This is regular thermal paste and not liquid metal (Conductonaut).Thermal Grizzly is one of the most highly regarded brands of thermal pastes on the market today, and their products are of a consistent high quality. You do pay a premium for their products though.In the resealable packet you get some basic instructions, a syringe with screw cap and a spreader nozzle which is used to evenly apply the thermal paste. Make sure you always clean both surfaces with Iso Propyl Alcohol first.The thermal paste has a very high viscosity so it's very thick and actually quite difficult to apply a thin layer. It can be quite messy too and is a nightmare to clean off of fabrics (and carpets!) etc.When used in place of stock thermal pastes you will almost certainly see a temperature drop of a few degrees, but I would say not numbers of 10-20 degrees Celsius. If you are seeing that kind of temperature drop then your original thermal paste application has been really, really poor.When compared to other high end thermal pastes you will most likely see little to no difference in temperatures. The idea of thermal paste is that it's supposed to fill the tiny voids between the CPU and heatsink, so a very thin layer is required. If you apply masses of thermal paste you may actually end up causing heat insulation instead of heat dissipation. I get much better temperatures when I use a smaller amount of thermal paste.Pros:- One of the best thermal pastes on the market- 11g is enough thermal paste for several applications and will last ages- Resealable bag to keep all the components together and air tight- Spreader nozzle to assist with even applicationNeutral- Like most thermal pastes it can be very messyCons:- Expensive- Possibly not much better than other high-end thermal pastes

To be perfectly honest, I never really paid much attention to which paste was better and blah blah blah. Years back I had to change it on my CPU and GPU and bought some AD and that was good enough. I've always been a believer that my temperatures were due to living in AZ and not having the AC set at 60 and all that non sense to have a decent ambient.Recently I found how wrong I really was with that when I upgraded my new CPUs 120 AIO to a 240 AIO and saw some pretty dramatic drops. Upwards of 25% with again using the stock stuff that came with the AIO. I then got around to building a new PC this week and opted to get this for the new application to this one and putting the old 120 on my old one.Was impressed, but wasn't entirely sure how impressed since the 3900x and case was new and I had nothing to go off.As I put my old 8700 PC back together I noticed something. My temps on load and idle after, were a bit lower, but not all that much. I was just happy they weren't any worse because I felt as if I botched it up with the crappy AIO mounting. I opted to keep it on and come back to check on it in a few minutes. Few minutes turned into over an hour and when I came back out, my jaw hit the floor! That PC setup used to run idle right now at 50ish C with the panel off. It was reading 33. THIRTY THREE! I would see the 30s with my PC next to my window, with it open in the winter here and only during boot/low use times. Now granted, I did have the GPU out and was using on board graphics, so not entirely sure how much that is affecting it, I'm sure it is, but to what degree I have no idea. I do plan on when I'm able to upgrade my GPU in the new system and put my old one back in there, revisiting to see how it goes. But I'm pretty confident that it's still going to be a noticeable difference and this stuff just rocks!If you aren't using it, you should be!

If you want the best Thermal Grizzly is a good go to for your needs. I have been using Kryonaut for 3 generations of laptop and 2 generations of desktop. You're paying for proven performance, reliability, and name brand.+ Excellent performance+ Well known brand+ Included dispenser for spreading+ Non-conductive/No cure time- Price- Still prefer the spatula lolOverall great paste but you'll probably see about 1-2C difference at most between this and other premium thermal paste. I still prefer the spatula though rather than the spread dispenser. You'll probably be good with the thermal paste that came with your cooler whether its the stock one preapplied or if they include a tube in this case Itemporarily used the EK Ectotherm that came with my block but again I only saw maybe 1-2C difference max if any. I have a large tube of MX-4 and have used NT-H1/H2 and again its already premium paste so unless you really want to squeeze out any more, it may not be worth it to spend that much. Would be nice to have included stuff like cleaning pads (NT-H2) and whatnot for how much you pay. There is also an upcoming Kryonaut Extreme that may squeeze a little more but again to most users negligible.This is usually my go to paste for my personal use, when I'm replacing a friend or client's build I usually just use MX-4 since its cheaper or whatever came with their cooler since its good enough. The only time I see that may need reapplying would be a prebuilt/oem system, an older/frequently used system or you're just bored and want to squeeze a few C. I use this on both my CPU and GPU, most of the time the preapplied paste from these vendors are already premium (shin etsu) or equivalent.Again you're mostly paying for the brand name and proven performance but how much you pay for the difference is up to you.

Never repasted my 2-year old laptop before so after some research, I decided to go with Kryonaut as it's apparently one of the best.My laptop has been thermal throttling from the factory & opening my laptop up revealed why: the factory paste is all dried up. So I completely removed the factory paste with 91% isopropyl alcohol & applied Kryonaut using the "pea method" (one dot of paste in the center).Thermal Grizzly provided a spreading tool & recommended that we use it to spread. However, there's a video on YouTube demonstrating a variety of paste application method with a transparent material. The results showed that the simple "pea method" spreads very effectively after installation of the cooling device.Use your best judgment & apply however you want, I am just saying what I did & here are my results:With the factory paste, running Unigine Heaven benchmark would have my CPU reach its max 90c limit & throttle while my GPU would reach close to 90c & throttle. With Kryonaut applied, both my CPU & GPU would be in the 60c-70c range. The Heaven benchmark is old so it doesn't push my laptop to its max, so consider this a best case scenario.Playing Black Ops Cold War at maximum graphical settings pushes my laptop to the limit, where the CPU would reach just below 90c & with significantly less throttling than before. The GPU now hovers around 75c-85c with no throttling. While it still seem to run very warm, keep in mind my laptop is very slim & the clock speeds are way higher & consistent than before, so I'd say the new paste did its job.I say it's money well spent if you are going to replace any factory thermal paste from your devices. Although to be fair, any reputable thermal compound will always beat factory paste. This is just my experience with Thermal Grizzly's Kryonaunt.

09-Dec-2019 UpdateI've since contacted the manufacturer regarding the issue I was having with this paste, and as it turns out there's been a batch of less-than-ideal paste a few years ago, which has been long resolved since, and was likely the cause of the issues I was describing.Thermal Grizzly were kind enough to provide me some proper Kryonaut paste which does not exhibit the issues I've mentioned below, and has pretty amazing thermal performance, which is beyond my expectations.I'm updating my rating from 2 to 4 stars.I would've updated it to 5, but the fact that you still need to watch out for not getting some of the old batch is a bit unnerving.*****DO NOT use this directly on CPU/GPU dies,or if you value your warranty.This paste is extremely rough and abrasive, it feels like there's sand mixed-in while spreading it. Attached are pictures of what my 3800X's IHS looks like after using Kryonaut. Upon trying to somehow recover from this by sanding down the CPU cooler's contact area I've also discovered that the abrasions are fairly deep. Using this thermal paste literally equals to sandblasting the surface of your CPU and heatsink.On top of that, compared to NT-H1 that I was previously using, Kryonaut seems to perform noticeably worse - achieving, on average, ~5C higher temperatures than NT-H1 does under identical conditions.Gonna be returning this, I really don't see why so many people consider this product to be any good.Two stars because it probably has better thermal properties than some of the worst silicone-based thermal pastes (albeit at the cost of destroying your heat transfer surfaces), but that's about the only positive thing I have to say about it.

I wanted to replace my PSU and decided to also replace the fan on my Noctua NH-U14S, so I went ahead and ordered this to use on my CPU as well. I also wanted to repaste my GTX 1080 Ti, and decided to use this for that.It's difficult to gauge its performance on the CPU vs the Noctua thermal compound I replaced with it due to the new fans with higher airflow (and the fact I installed two in push-pull instead of just one like the heatsink originally came with). The GPU is a completely different story though, as the only change to it was the thermal compound, and it was running a good 5-8 degreed Celsius cooler after being repasted with Kryonaut. Since this was an ASUS ROG STRIX card,and they use pretty good thermal compound to begin with, it's usually difficult to reduce thermals very much just by repasting the GPU, so to see a drop of even 5 degrees C is pretty good after a repaste (granted that could have simply been due to the age of the card and degradation of the factory applied paste due to dry-out).The paste is also easy to work with. Application is easy, and you can just pour enough on the CPU heatspreader to cover it completely once you put the heatsink on. Gamers Nexus did some testing, and they found it doesn't matter how much you use (the amount used had no effect on thermal performance) as the heatsink just forces the excess thermal compound to ooze out the sides and down the CPU socket if there's too much. Since the paste is non-conductive, the worst you can do is make a mess and waste a bit of the paste.

I have to start by reporting this paste was very difficult to spread on my cpu due it it being so sticky and stringy. I've watched videos of this paste being applied and it was nothing like my experience (it wasn't the my technique the paste was like glue where the videos showed it to be like liquid). I don't know if the one I received was defective, it was only bought a few days ago so shouldn't be out of date.If it wasn't for such good results I would have certainly dropped at least 2 stars, it really was that bad.Anyway onto the positive. I had the chance to test this against arctic mx4 and arctic silver 5 thermal pastes on the same system which consists of:Intel 7800x with a coolermaster master liquid pro 120,gtx 1080ti and 16gb 3200 ddr4 memory. The motherboard is the asus strix x299.For simplicity I used the furmark preset 4K test, everything was running at the normal clock speeds.The resulting highest CPU temperatures were:Arctic silver 5: 55 degrees.Arctic mx4: 52 degrees.Thermal Grizzly: 45 degrees.As you can see from the results the highest recorded temps showed best results from thermal grizzly. Something I also noticed about thermal grizzly was the range of temperatures per core were within 1 - 2 degrees of each other while the other two varied much wider (around 6 degrees in some cases).I don't think you will be disappointed with your results if you buy this thermal paste. I just hope removal isn't as bad as application!

The original thermal paste that came with the workstation would not cool the CPUs properly. At full load the 2nd CPU would throttle to around 138W instead of the full 150W it was rated for. The CPUs are in series, that is the case fan blows air into the first CPU, which blows air to the 2nd CPU, which then blows the air out the back of the case. Not ideal at all, but it is what it is.I then tried Arctice Silver 5 and that cooled an additional 5C under full load, but it would still eventually warm up to 90C and start throttling. I then tried the Kryonaut and it cooled an additional few degrees when the fans are set to auto in BIOS and keeps it from throttling under full load.It also seems to distribute large changes in temperature better allowing time for the fans to speed up.If I manually set the case fans to 50% it has no problems keeping the 2nd CPUs under 83C when the CPU is using well tuned code at full load. Checking the power usage it will start off at 170W and then back down to the sustained rated 150W... finally my CPU is no longer throttling.After I upgrade my CPU heatsink and fan it should have no problems, but first I have to find the right length of screws because Dell doesn't like following cpu socket standards...grrrThe applicator device supplied does waste a bit of paste, but unless you plan on using this multiple computers it's not a huge deal. It spreads fairly easily if it's not cold.

My laptop has a i7 8750h, which anyone who has had the same, or newer knows runs very hot when under heavy use, and usually thermal throttles.Using this I've managed to get my temps to a manageable temps of about 83-84 degrees at max use, which has stopped it from throttling, unless bench-marking, and usually averaging between 70-75 degrees during gaming, and under 50 during general web browsing. Which I've found especially good considering the hot weather we've had the last couple of weeks.Which was a huge improvement compared to especially the factory thermal paste, and even the MX-4 I tried (which did lower the temps a bit, but would still often thermal throttle, and just run hot),I'll be keeping the MX-4 tube for using on my desktop as it's temps are lower and easier to cool.It's definitely one of the more difficult to apply compared to some of the thermal pastes I've tried in the past, as its slightly gooey, and sticky, but the included attachment makes applying and spreading the paste easier during application than I found the 1g tube.I'll be keeping the Kyronaut just for if my laptop needs re-pasting in future, and not waste it on my desktop as its temps just down need the extra cooling, and as the cost of the tube is definitely expensive, but if you have any issues with temps being slightly too high it's a great option, especially if you aren't willing (like me) to try and use liquid metal.

Taken apart my HP Spectre x360 and my original release PS4 so I can give them a proper cleaning and upgrade, back in December of 2019.The laptop is roughly less than a year old and I was in the process of giving it a Samsung Evo Plus 1TB. I cleaned the cooling system and was surprised there wasn't as much dust as I thought. But the problem lies where the fans are always kicking on at full speed. I use it for everything and while the external GPU (RTX2080Ti) is cool, some CPU intensive games such as PUBG require a lot of brainpower. The i7-8750h seems to be getting too warm for my comfort. This new thermal paste is allowing heat transfer to be the most efficient it can be.Cooling works so much better and even my CPUID HW temps are much lower.On to the Playstation 4. I got this baby brand new when they first released in December of 2013. After 6 full years of gaming from Battlefield 4, World of Tanks, The Witcher 3, and much more, it's gotten a deep cleaning. The fans and heatsinks were full of dust and dirt from every single place I've taken it to, including two deployments and being stationed in Korea. I cleared those out and applied this thermal paste onto the CPU and GPU. This sucker isn't kicking on its fans at full speed anymore even on light gaming. Even at hardcore gaming or running the new, intensive Tom Clancy Ghost: Breakpoint, things are still quiet and comfortable without the shrieking fans.

I have always been sceptical of the benefits of some of these pastes but this one has proven me wrong. After reading some of the product reviews I nearly changed my mind on this paste as some people said it is to thick and hard to spread. My 5.5g tube had the same consistency as any other paste, it is slightly tacky but is easy to manipulate with the supplied plastic spreader.I applied this to a 2019 RTX 2060 Razer blade 15 base which had MX4 paste installed and was getting 92c on the CPU and 78c on the GPU. After applying the Kryonaut paste exactly as in the picture I am now getting max 79c on the CPU and max 70c on the GPU playing Modern Warfare on highest settings.Needless to say these results are not shabby and I am very impressed, hopefully it will extend the life of my machine, just glad I purchased the larger tube! Also worth mentioning I achieved these results 48 hours after install, the initial temps were slightly higher so well worth waiting a couple of days for best results.For those who want to know the Blade has a core i7-9750H CPU with -140 undervolt on core and cache and turbo set on all 6 cores at 3.6GHz. The RTX2060 has an 185MHz overclock and 500MHz GPU memory overclock. I also replaced all the thermal pads on the heat sink for Gelid GP extreme 1mm variants, (doubled up in a couple of areas), which may have also contributed slightly to the GPU temperature results.

Like others I have found this heat sink compound to be on the thicker side compared to others on the market. A simple solution to this is to heat it up first in a cup of warm water. I did this and it definitely helped.There are loads of different methods to apply this stuff and different people swear by different ones. At the end of the day only three things matter:1. Even coverage across the entire heat spreader2. No air bubbles3. Not too thick, not too thin, just rightLots go for a dollop in the middle and let the pressure spread it out. I prefer to just spread it all over the surface of the heat spreader on the CPU and then apply the cooler (in my case, a Fractal Design S24 - very quiet,very efficient). I can't compare to anything else as this is all I have used in my PC, but I built this for silence and airflow, and given how stable things are and how quiet things are, I think I achieved that.At the end of the day there are loads of different compounds to choose from, and Arctic Silver seems to have become a bit old-fashioned now. If you are brave enough, go for one of the liquid metals, but those can be messy and if you spill any on the motherboard, you have a nice cleanup job to do to not fry it.So yeah, not the easiest to spread but then the best things in life often take some effort.

My brother and I each own a gaming laptop. I have an MSI PE62VR 7RF (1060gtx / i7-7700hq) and my brother has the Dell XPS 15 9560 (1050 ti / i7-7700hq)We both have already replaced mfr thermal compound with TG-7 in the past. Our temps were a noticeable 13-17 degrees difference on both CPU and GPU after running MSI Kombustor - (GL)FurMark-MSI benchmarks for an hour vs when TG-7 was used.No complaints, well done.UPDATE 4-30-2020A couple of months later and definite noticeable improvements in this products ability beyond what my initial stress tests showed.I've had steady temps running high settings in 1080p 144hz in Mount & Blade II: Bannerlord for well over 8 hours now and don't reach above 75C CPU,65C GPU. Note, I've stressed with MSI / Furmark programs for hours and couldn't push it as hard as some of my more demanding games. Typical application, browser and media file use leaves me around 48-50C CPU, 50-54C GPU but never higher. Idle around 40-45C CPU, 30-40C GPU. For a 15.6" laptop, this is very pleasing as I was breaking 70-80C and even upwards of 90C during demanding games with the stock paste from MSI and what I replaced it after, TG7. Kryonaut has far surpassed my expectations.Lifetime customer acquired.

Unless you go with a liquid metal paste, you won't get lower temps with anything else. But those are messy and can destroy components if improperly used, so this is the next best thing.It's expensive compared to others, but it is definitely the best non-conductive paste if that's what you need. Also, you may want to go with a smaller tube than this unless you do allot of work with PCs. You should be able to do at least 20 systems with this, including the CPU and GPU.I'v replaced the thermal paste on all my graphics cards with this and saw a pretty large drop in temps. Allot of thermal pasts seem to choke when it comes to GPU usage, but this paste doesn't.For example,my GTX 1080 dropped over 10°C from the factory paste, allowing the cart to boost to around 2050Mhz with minimal fan noise. Before replacing, it would hit 85°C and back down to ~1700, but now maxes at 70°C and generally runs at 55-65°C under a typical gaming load.As for CPU cooling performance, I can only compare to MX-4 since that was my previous go-to paste. You should see around 4°C better temps if you replaced it with Kryonaut. But you would see an even larger difference from a stock paste that comes with most heatsinks or water blocks.
