Kryonaut Extreme Thermal Grease
Thermal Grizzly's Kryonaut Extreme is an improved version of their pc thermal paste, with the highest thermal conductivity achieved through the use of smaller particles, a thinner minimum layer height, and improved low-temperature application.
Great Compatibility
Compatible with almost all cooling solutions, including air, water and even liquid nitrogen (up to -250°C). Thermal Grizzly Kryonaut is recommended for applications that require high thermal conductivity at room temperature – e.g. between a silicon chip PC microprocessor and heat sink.

TG Cleaning Wipes
TG Cleaning Wipes are cleaning cloths for cleaning surfaces so that thermal conductive materials such as thermal pastes or liquid metal can adhere well and thus develop their full thermal conductivity. Assembly aids such as the TG Kapton Insulation Sheet or the TG Shield protective coating also adhere better to cleaned surfaces. TG Cleaning Wipes are packaged as a practical complete set of 40 cleaning cloths.
- Wet wipes for the removal of thermal pastes
- Removes grease residues (e.g. fingerprints)
- Packed in ten double packs for easy storage
- A total of 20 dry wipes and 20 wet wipes

The wipes - they work well. You get a bunch of them and they each come in a set of two. One to take the bult of the paste off while the other is to do final cleaning. I didnt notice any difference in composition between the two wipes, but I appreciated that TG did think about the process of cleaning off thermal paste and how trying to do it all with one wipe might get messy.The paste - application was easy. I never used the little applicator spreader thing and didnt care to use it this time around since I've seen that the X method has worked just fine for me over the years as evidence shown when replacing heat sinks. I recently got a new AIO and used the paste here. I didnt do any comparative analysis between thermal pastes, however I can report that my CPU (Ryzen 9 7900X) never exceeds 50C in normal use which is fantastic. I can say that I am probably getting the most out of my AIO with the use of TG thermal paste and that I'm not leaving any performance on the table due to the thermal paste.

I can't speak on the longevity of this paste just yet, but MAN everything else is so worth it. Yes it's a little pricy for some thermal paste, but I say it's worth it. I used this stuff to repaste my gpu, an RTX 3080, which is a little heatpack. Before repasting I was pulling about ~82 degrees temps in a game like Kingdom Come Deliverance 2, and just after repasting with this stuff I dropped a whole 5 degrees! That might seem like a small amount, but not hitting 80 degrees makes it so the fans don't really ramp up, which helps with the life of the fans on the card, as well as the noise.You get a couple cleaning pads which make the clean-up of old paste so much easier, and when it's time to put this stuff on it comes with some spreaders, and it comes out smoothly, and spreads just the same. Recommended.

This stuff is fantastic. Made my cpu 10 degrees cooler (Celsius)”.

Ordered this: Thermal Grizzly Kryonaut Extreme - 2 Gram - Extremely High Performance Thermal Paste with 20 Cleaning Wipes - to use when replacing a CPU cooling fan that failed on my kids computer.This stuff came in a branded retail style packaging with good instructions. I especially like the cleaning wipes, perfect for getting that old paste off the CPU and then getting it clean enough for the new stuff. Typically I have used the cheaper silver stuff in the past and had decent performance. Without doing a head to head comparison it is hard to know if this premium brand delivers a temperature savings worth the price. As I was having fan issues hard to compare the temperature performance but seems excellent quality to me. The surplus wipes are a nice feature.

Best I've ever used. There may be better out there, but I don't know of it. I'm running a solid and consistent 3 degrees cooler after applying this stuff. Lets see how long it holds up. As of now, I couldn't recommend more.

This is not my first time using Thermal Grizzly Kryonaut Extreme. The performance is so consistent that I keep getting this whenever I need to cool down my CPU/GPU on a new device. The paste quality is good and application is easy. The paste temperature reduction performance is excellent and it easily reduces 7C-10C on a CPU. The inclusion of wet and dry cleaning wipes is new as they were not included when I started buying few years ago. This is good value for money and the only paste you should be getting for your CPU/GPU.

I'm really picky on the items I use when assembling my PC, and one of the most important aspects to me is proper cooling. This thermal paste reminded me of another, based on its pink color, and I was not disappointed, not to think or to thin and was easy to spread ( Yes I spread this paste) its one of those that I do not just put a "dot" and be done with it, I cover the entire heat spreader as evenly as possible. The temps were really nice, I would say about 4c or more at times, staying under 76c at full load ( this is with a tower air cooler also). I'm pleased with its performance, and my Next project will be to re paste my 4090 with this, I think it will be worth it in a long run. Especially since my CPU's old paste was no longer paste it was more chunky So it was a much needed time to re-paste.Highly recomend, a little goes a long way with this also by the way, you don't need to over do it, just enough to cover the IHS. This is based on my opinion from installing several CPU's.

I do a fair amount of electronics work with computers as well as handheld devices, so I wanted to try this brand out.One of the worst parts of putting new paste on is cleaning the old stuff off. This kit comes with 10 pads for cleaning off the old gunk and making sure the new surface is ready for the paste. They work well and are a great addition to this kit.The paste itself comes with a nice applicator that makes it easy to apply and smooth out the paste which is unique to this brand.As far as the paste it concerned, it works well, as well as some of the others I have tried. I feel like at this point most brands are going to give similar performance, so the extras of this kit are what really set it apart.I would recommend this to anyone who needs better thermal performance from their electronics.
