    • 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

    • one of the best of its time.
Style: i9-11900K
When I was in the market to create a PC, this CPU was top of the line. and I got it, and it has not disappointed me ever since. works great and keeps on working. I have overclocked it and underclocked it. stress tested it for a few hours, and it managed to keep running. I love my PC and this CPU.

    • Still a great gaming CPU even after 3 generations.
Style: i9-11900K
This was Intel's top line CPU in the 11th generation; it used the LGA-1200 socket which was only minimally different from the LGA-1151 socket (1200 pins vs. 1151 pins). The motherboards for the LGA-1200 required only small changes in production spec, and the coolers made for the 1151 chips work perfectly on the LGA-1200. By contrast, the 12th generation, using the LGA-1700 socket, required an extensive redesign of motherboards, and the coolers that got adapted over from the LGA 1151/1200 didn't really work properly on the 12th and 13 generation Intel CPUs. This i9-11900K will pull about 170 watts through the socket at factory overclock 100%, and that's right on the limit of safe operation for the vast majority of air or liquid coolers on the market today. ... show more

    • 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

    • A really good value from Intel for Intel based motherboards. It is capable of overclocking.
Style: i9-11900K
This LGA 1200 cpu is robust and easy to overclock assuming your motherboard supports overclocking and your cpu cooler supports it. The base 3.5 GHz can easily support overclocking to 5GHz. I used the Intel Windows overclocking program and it was easy to do. The cpu installs easily and runs well.

    • i9 11900K to the rescue
Style: i9-11900K
I had an i7 10700 that went kaput on me, so I figured, why not upgrade to the overclockable 11900K, since it was only about 50 bucks more to the the fastest CPU my mobo can handle. I did install water cooling because it does run warm, but let’s just say this. My computer now works at warp 9.975. With the i9 10900k, a Nvidia 3060/12gb, and 128 GB DDR4 at 3200mhz, on userbenchmark website the lowest score I got was a 104% for gaming (UFO ranking). I overclock it a lot and it holds up well, and stays under 50c with the water cooling for me. 11/10, would recommend, promote ahead of peers. ... show more

    • Great CPU
Style: i9-11900K
when i upgraded my desktop i decided to go intel core i9 this time. all my previous build was a 6th generation core i7 6700k. it ran fine but it wasnt up to running windows 11. so an upgrade was in order. besides, my old board was starting to fail. i originally bought a 10th generation core i9 10 core but that cpu was junk. there wasnt enough PCI-e Lanes to support my drives and usb devices. this is a limitation of 10th generation CPUs not a limitation on the board. my video card (RTX 3070) took up most of the available PCI-e lanes which took out most of my drives. so i went to the 11th generation i9 8 core instead. very happy with it. it solved all my PCI-e lane issues. i am able to run all my devices and drives. the cpu clocks at 5.3ghz stable i have water cooling installed. i see zero problems with this chip. its fast, its stable im plenty happy with the upgrade. the board is a MSI MEG z590 ACE Gold. i have 64gb DDR4 3200. ... show more
