    Great cooling performance. Installed on a 9050x with an arctic cooler 420 and my temps stay very low.

    Great product. This helped to reduce my processor's temperature by approximately 15-20c compared to the compound that came with my cooler.

    This is the best thermal paste I have ever used. My CPU stays under 40c. I even used it to repaste my GPU with excellent results. The picture is my computer with thermal lighting. I have never seen it change to yellow or red.

    I have tried several pastes, including Corsair lines. This is the beat Corsair offers. I failed twice using a PCM strip during re-padding of my gpu, and used this on the third attempt. My gpu runs very cool.

    Installed on a Intel 13900K CPU. It was very easy to apply and did its job! No CPU overtemps and has been running smooth.

    Don’t want to buy thermal grizzly and have a messy install but want your CPU to stay cool? This is the stuff! Easy to apply and works like a charm.

    Great new paste from Corsair. Its on pair with newer high quality pastes like Thermal Grizzly Kryonaut or Arctic's MX-6, if not, even better. Previous Corsair pastes were poor performing in comparison with the competition (like the older xtm30 or xtm50) but not this one, believe me. I have done some comparisons and its within range of the higher performing ones out there. Certainly not the cheapest, however its readily available in their physical stores if you need it on a pinch (most of my local Best buy stores carry it) and you don't need to wait for shipping. They include an nice stencil and applicator stickers so you can perform a nice and even application on your cooling device. It's a good amount for the price and the consistency makes it easy to apply. It's not too runny and not to thick, kind of in the middle. Highly recommend it!

    This is my preferred thermal grease for all my builds. Easy to use (I use the pea method), easy to clean up, works very well even on hot CPUs.

    I had been running the same CPU for 5 years. 12 core was good enough for my purposes and still is. The issue that I didn't know was that my old Paste had dried and stopped being useful. After cleaning off and reapplying (with Corsairs easy to apply tools included) my core temps went down 5-10c to where I think it was when I first applied paste back in the day.

    The best thermal paste kit

    I have used a lot of different thermal pastes while building computers and this was probably the easiest to use. It comes with a full kit to apply it and a card to flatten it across the CPU. This has to be the simplest way to apply thermal paste. I use it with an AIO and my temps on an 19-13900k stay below 85 at full load. I would recommend this to everyone who needs thermal paste.

    14700k I saw lots of negative reviews regarding Corsair's thermal past... I ended getting this because it was the only one available at the time. I received excellent temps and had no issues with the application. My only critic is that was a little expensive. After finishing my build, I have no regrets.

    My pc was overheating to around 90-100 degrees Celsius because the thermal paste was old. Reapplied with this paste and the temps dropped back down to 30degree Celsius after a few minutes.
