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.

Excellent paste, but very small quantity means you can't waste any. One tube was able to comfortably mount my 9800X3D, and I barely had just enough left to repaste my GPU. I did not waste any, so you have to be careful not to make any mistakes with this small quantity. If you're only using the paste for one CPU, you will likely have just enough to make one mistake, as long as you aren't putting a ton of paste on.As expected of Thermal Grizzly, excellent product. Temperatures are low, no signs of pump out after three months. Would absolutely buy again.

Edit - I added some images above to show the contents of the package. I have purchased this paste several times now. Best non-conductive paste on the market hands down. (End Edit). I replaced MX2 thermal paste with this, temps went down from 18C idle 32-36c under load on FX6300 with a GTX 1060 on Hyper 212 Evo to 15C idle and 30-34C while gaming. Prime95 before hit 42C now it tops out around 38 hit 40C one time for a second. My 212 Evo has Duel fans in push/pull config. Great paste. Bought it just to try it out before using it on new build I7 7700K and MSI Z270 Gaming M7 motherboard is on the way. Edit 9/2020 - Many years later and this is still the best non-conductive Thermal Paste you can buy. I’ve since got really big into PC gaming and building PCs for people/clients. I currently have new full tubes of Cooler Master Masterpro Gel Nano, Noctua NT-H1, and Artic Silver 5 which is the only one of the bunch that requires a setting time. These are all great pastes. Most people would say the Noctua NT-H1 is the best but from my experience out of the ones listed the Masterpro Nano performs just a touch better but isn’t as easy to apply. I recently upgraded my system. Ryzen 3800XT, RTX 3080 on the way to replace RTX 2070 Super, 32GB G.Skill 3600mhz CL 16 ram, Asus Prime X570-Pro board, several ssds, two NVMe drives one Gen 3 and one Gen 4, a single 500GB Western Digital Black HDD I’ve had since 2013 to use to store backups and gaming videos/pics, a EVGA G3 Supernova 850 watt 80+ Gold Fully Modular PSU, an internal WiFi/BT 5.0 PCIe card all in a Cooler Master Masterbox NR600 Mid Tower airflow focused mesh case with a glass side panel. My case has all PWM premium Noctua Chromax fans. 3x120mm front intake, 2x140mm top exhaust, and 1x120mm rear exhaust. My CPU cooler is Noctua N-DH15S replaced with duel 140mm Noctua Chromax Black/Blue fans, and the Noctua Chromax Black/Blue heatsink covers to make it look nice. Overall I’d say I have a pretty upper mid/high end sustem. I game at 1440p max settings 100+ FPS regardless of the game. I have all these pastes here and I STILL ordered another tube of Thermal Grizzly for my processor. Nothing wrong with the pastes I listed but this pastenhere is amazing and out performs them all. This is in tons of benchmarks just hit up google. It requires no curing/setting time, is non-conductive, easy to apply, and will give you on average an extra 2-4 degrees lower temps on your cpu. That might not sound like much but when you overclock everything and your system draws a lot of power over the course of months, years, and long gaming sessions having a processor that runs cooler is always better. Not only does it allow it to potentially overclock higher as well as boost higher and for longer. But it also if you run your cpu stock allows your cpu cooler to have an easier time cooling it thus your fans can spin at a lower rpm for the same results which equals less power and a silent system. Overall it’s a bunch of minor things that depending on the user might make a nice difference in their setup. For me spending 8-9 dollars to have the best possible paste I can buy is a no brained. A single 1 gram tube is enough to do 3 applications easily. With my mentioned system above using my case which has great airflow with my Noctua N-DH15S in push/pull my CPU runs in the lower 30c idle, around 50-55C in games maxed out no matter how long I play, and using Prime95 max power max heat stress test after 20 mins which is enough time to hit its top out point it peaks at 68C. That’s on a Ryzen 3800XT that’s set to run wide open with all I could get out of it. You will not fine a better non-conductive Thermal Paste so if the best is what you’re after proceed to hit the buy button.
