    One month in and this seems to be working great in my new pc build. This is on a Ryzen 7 9800x3D CPU and a ThermalRight Peerless Assassin 120 Se Air cooler. The temperatures are reading around 50C with basic operations and 62C gaming on Baldurs Gate.

    Might be a little overpriced, but the template you get with this item helps insure you do not mess up applying paste to the CPU which for someone who is doing this for the first time is worth the price. Be sure to follow the instructions and you will be fine, you have more than enough paste to do 1 application, and possibly 2 if you build computers as a hobby like me.

    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.

    Good syringe, thermal paste, handy applicator tools also! Crucial to good system operation to have good thermal dissipation on CPU.

    Can't go wrong. It's pricey, but it's worth it.

    Works as well as the liquid metal junk that will destroy your motherboard. In fact, I had to clean out the liquid metal junk out of my motherboard, and then I applied this. CPU and GPU were a lot cooler afterwards.

    Amazing Stuff

    I recently replaced the stock thermal paste on my CPU with the CORSAIR XTM70 Extreme Performance Thermal Paste, and the difference is night and day! The stock paste was hard and didn't provide great cooling, but the XTM70 has significantly improved my system's thermal performance. The XTM70 paste is easy to apply and spreads evenly, ensuring optimal contact between the CPU and the cooler. Since switching to this paste, my CPU temperatures have dropped noticeably 41c, even under heavy load 65c. It's a bit pricey, but the performance boost is well worth it for anyone serious about keeping their system cool.

    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.

    Pretty thick and somewhat difficult to apply (not sure if it's just the consistency but it just kept stretching out), but I've had pretty great thermals and it's done its job.

    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.
