    • Still going strong
Style: i9-11900K
Ran great, till I fried it! Hot this CPU back in 2021, was still running fine until I messed with some wires i should not have and fried it. My gaming pc runs great on it and I've had no issues, hence why I ordered a replacement for the one I ruined.

    • A Catch-Up Review from a 2022 i9-11900K Purchase
Style: i9-11900K
I am not a gamer by a long shot, but wanted a powerful Intel based CPU riding on an 'Asus Maximus Extreme Motherboard' along with a Asus RTX 4090 GPU. I purchased (1) of the most graphic intensive AAA game titles and a few CPU intensive military strategy simulation games known for their heavy demand for CPU physics computations. My Core i9-11900K which I purchased in 2022 performed admirably well on all accounts. Absolutely no complaints. Some reports say that the i9-11900K runs hot and sometimes above the 100°C mark? But that was not really the case with me or the many others when they installed a high quality 360mm or above sized AIO water cooler. My very demanding combat simulation (Command: Modern Operations) never presented a heating issue with the i9-11900K and with my over 80-hours of heavy duty play. For good measure my Cosmos C700M EATX case also includes a total of (7) additional independent Noctua cooling fans, which of course benefits the cooling within the massive interior of the enclosure. Overall I am extremely satisfied with INTEL in general and recommend the i9-11900K and or its newer siblings now as a very good buy! ... show more

    • Great Processor But Can Run Hot Unless Tuned!
Style: i9-11900K
Upgraded from a 9900k and had a hotter running PC. Couldn't figure it out at first and found myself checking my AIO, reapplying thermal paste, checking settings, etc. After research I was able to discover that given it a slight undervolt helps. What ended up helping even better and easier was ticking down the performance in the Performance Menu. In those option by simply ticking down the processor to 99% my temps went down to 55 for most of my games from initially running at average 80-85. This tuning comes without a noticeable hit on FPS except while playing "Squad" (a single core use cpu intensive game). With that game I do lose at least 10 fps by having the processor at 99%. This is not that big of a deal as I can easily tick it up to 100% for Squad and just put up with the 75-80 temps! Happy that I can at least play most of my games at a good temp while gaining good performance by this upgrade! ... show more
