    This thermal paste is one of the best! I hough a refurbished LG gram and it was idling at 60 degrees and terribly thermal throttling when it reached 90 degrees. I opened it up and applied this paste and now my pc idles at 30 degrees! Does not thermal throttle anymore and games that ran at 25fps now run at 40-50 which is double the performance! Only downside is this issue is really expensive! But it's well worth it!

    Excellent thermal paste. WARNING‼️ it really is very thick and difficult to spread compared to other pastes. But, the stencil worked great after improvising with painters tape and spreading the paste directly on the CPU to prevent any excess from going anywhere it shouldn’t. I refused to waste any paste on the AIO’s massive copper plate (the stencil is huge compared to the CPU surface area. After finishing the build, my i9-14900KF stays cool, the temp idles at 30 degrees and I haven’t seen it go above 55 while installing all my software & running all my updates while exploring ASUS Armoury Crate and using Aura Sync, including the live wallpaper. I’ll post an update the performance / thermals after I’ve benchmarked the computer and played a few games. So far though it seems great.

    Ended up going with a new build. Got this paired with a corsair 150i LCD on a 11900kf i9.. gaming even cpu intensive games like new world. Cpu doesnt go above 55 ever. On quiet settings. Before i had the xm50 and i would say maybe a 10c difference on the dame 11900kf. Well see how it holds up 6months to a year from now

    I built my friend's rig about 3 years ago for data science applications. It had been chugging along productively until recently, when the temperature started moving up. We thought maybe the thermal paste had dried out and the quickest possible solution was to replace paste. I bought the Corsair - XTM70 Extreme Performance paste. After applying the paste, the temperature was back to acceptable levels! The rig has been running non-stop perfectly since!

    Great product. I was skeptical of buying this at first but I’m glad I did. Its kept my temps pretty low and I’ve been using it for several months now. I love that it comes with a template so I can get an even placement of the thermal paste. It comes with plenty so you can use it more than once.

    My CPU doesn’t reach 75 deg C even I played call of duty in max settings (35-38 deg C in idle). More viscous compare to other thermal paste.

    For ridiculous cooling setups

    Using on a 5900x running at 4.7ghz all core and applied to my rig strix 6900xt. CPU and gpu have 240mm aios, fans replaced with 3000rpm noctua industrial fans @ 24v with their own 24v power supply’s. Max cpu temp achieved over 3 3d mark runs was 55deg C and gpu at 52deg c. In a Corsair 5000d airflow. This Corsair thermal paste had me a little nervous at first because I honestly didn’t think it would be enough for the insane things I do in regards to room airflow and additional cooling provided by my windowless ac, get, try it, I’m pretty sure you will love it, only downside it’s like $25.00, but it is what it is. ***that gpu score is only that low until I get a dedicated breaker installed***

    Best paste I’ve used. CPU was running between 60 and 70 gaming now runs between 50 and 60. I also swapped the loading bracket to get a better contact with the AIO, and am using a 360mm radiator.

    I have ran this with my Noctua NH-D15 several times as I was out of the noctua juice it came with, can honestly say performance was right on par and beat my expectations.
