Thermal Grizzly Kryonaut - 1 Gram - Extremly High Performance Thermal Paste - for Demanding Applications and Overclocking CPU/GPU/PS4/PS5/Xbox

Let me preface this whole things by saying that Kryonaut is a really good thermal paste for cpus. It helped decrease my tdie temps by a massive margin (over 5 degrees), and thermal conductivity is impressive while being easy to apply. But putting it on gpus... let's just say I bought this before I had actually done proper research because I had heard so much good about it. *sigh* time for the long boring essay...**TL;DR: pump out is bad for long term thermals and this has especially bad pump out. anything with IHS (cpu) gooood, anything without (delidded cpu, gpu, socs, laptops, etc.) baaadA lot of people tend to think thermal paste is either all the same or only look at conductivity. However, with this paste, I figured out the hard way that thermal paste is way more than heat dissapation. Pump out occurs through many repeated cycles of rapid heating and cooling and causes the thermal paste to dissipate outwards and leave little to no paste on the core, usually through a long time period (3-10 years, depending on quality). This is more prominent on gpus as those have no ihs and tend to heat and cool more violently than cpus do. Thicker, more viscous thermal pastes are less prone to this. Unfortunately, this thermal paste in particular has especially terrible pump out because it's thin and watery.It worked WONDERS on my cpu as I mentioned earlier. An already great temp of 65c or so fell to 55-60 while gaming in ambient 22-27c. No pump out issues and it stayed like this until I changed coolers.On my gpu, it worked well - at first. 55c with 8 degree delta between hot spot and core. It almost instantly (within a month or two) started to have bad deltas (meaning pump out was causing die to heat up in certain spots more than others). Delta was around 8c, then slowly rose to 15c+ (worst I saw was 20c) and core temp also rose from 55c to 60c to 65c. When I replaced it with a thicker, much more resiliant thermal paste (thermalright tfx), it has been consistently good at ~57-61c and 10-12c delta for the past 3 months.All in all, it's a great paste that has amazing thermal conductivity (although that standard is nonexistent). your cpu temps will drop if you are replacing old or otherwise low quality thermal paste. However, it's a lot of money for the amount of paste you get, and being the way it is, it is not designed for direct die contact, so bear that in mind. Be aware that different thermal pastes have different use cases, and this is not for gpus. If you want that from thermal grizzly, there is hydronaut and liquid metal (though I have not used either). I personally just recommend arctic mx5 and tfx and maybe noctua nt-h2.

The tube is small, is almost exactly one application. I had used the paste that came with my CPU. I would often see temperatures reaching close to 90 degrees. So I removed the water cooler, cleaned the top of the Processor and the copper plate on the cooler. Applied this paste and things are much cooler now during a heavy gaming session the temp goes no higher than 82 degrees now. It is a bit solid for application. I left the tube out in the sun for about 30 minutes and it made it a lot easier to apply. It comes with a little spatula that is solid enough. Apply evenly, leave no empty patches on the CPU. It does not smell for very long. If you have metal allergies wear gloves when applying.

In all fairness, this is just thermal paste. Whether or not it's exceptionally well made, or performant, I can't say. I have no means of testing the quality of this paste over others, but please, for the love of god, buy this paste, and put it on your old graphics card. I have a GTX 970 (2014), and was beginning to believe it was beyond outdated. I changed the paste (from the original stock paste), my temps went down 20C, I got an automatic 200MHz boost, and was able to crank out another 115MHz with a modest OC (peak temp of 65C in benchmark). My Time Spy GPU score went from 3343 (stock paste) to 4050 (new paste, +115MHz Core clock, +125MHz Mem clock). I didn't bother to try overclocking with the stock paste, as I was already pushing 90C with the stock settings.If you're having thermal issues. If you card doesn't perform like it used to. If you think it's time for an upgrade, some or all of those may be true, but before you do anything else, do the smart thing, and give new paste a try. Easily the best $8 I've ever spent on my PC.This will absolutely have an impact on CPU performance as well, PROVIDED THAT THE EXISTING PASTE IS OLD. This will do effectively nothing if you're replacing relatively new paste, especially if you aren't pushing your hardware particularly hard. I went out of my way to repaste my much more recently installed Ryzen 3600 (again, stock Wraith cooler paste), and saw zero performance improvement, simply because the existing paste was doing just fine.I would recommend against spreading the paste with the included spatula, or at all. GamersNexus has done extensive testing on thermal paste application, and their research has shown time, and time again, that the best application method is to draw two, intersecting lines connecting the opposite corners of the heat spreader/die, making an "x" shape, and allowing the plate of the cooler do the spreading for you. You should also exercise extreme caution when applying paste to an exposed, silicon die, like that on a graphics card. If you tighten the screws of the cooler unevenly, you can easily crack the die, destroying it. CPUs, at least modern ones, will almost always have an integrated, aluminum heat spreader on top of the die. You can still damage the die underneath if you apply uneven pressure, or knock the cooler around, but the heat spreader does provide a considerable degree of protection. Still, be careful anytime you're working inside your computer. More often than not it's a difficult thing to mess up, but you're better safe than sorry.Absolutely, 100% recommend this product. I trust the sources that directed me to this paste over others, and its performance has exceeded my expectations. Breathe new life into your old hardware. It's $8. Give it a try before spending several times that on new hardware.
