Best CPU my poor little motherboard can handle. Have been using this for a couple years now (I forgot to review). It works with air cooling at it's default 3.50Ghz, any overclocking needs watercooling BADLY. If you are stuck with a LGA1200 socket, this is the best you can get

The seller did an amazing job. The item came even sooner than expected. The bad news is that I installed it in my previously flawless running machine. The reason I upgraded from my current i910900k is that I wanted to enable the NVME.2 4.0 on my SSD. I already had the drive and a Z590 motherboard so why not right? I put the new i9 11900k In and it started and enabled the 4.0 on my NVME. Yay right! Literally with in a couple minutes I received a watchdog timeout error. (This is caused by CPU cores failing to communicate with each other.) I called Intel tech support who was less than help full. I updated all drivers and still didn't work. I did notice my CPU temp was running over 100c. Odd because I have the best nactura CPU cooler they sell. I decided to upgrade to a liquid CPU cooler and that brought my CPU temp down to around 85c. That still didn't fix the time out errors. I put my old CPU back and all is happy. I ended up sending the i9 11900k back but at least my i9 10900k is nice and cool even at 45% overclock. LOL

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.

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!

I've been using this CPU for four years now. This isn't a one-day first impression. This is a long term review from someone who has lived with it and regretted it every single day. I bought it by accident thinking I was upgrading but I quickly learned the truth. If you run a 10th gen Intel CPU on an 11th gen motherboard you are forced to use the PCIe 3.0 slots and cannot use the top PCIe 4.0 slot. So you upgrade to an 11th gen CPU thinking you'll finally get that PCIe 4.0 speed. And you do. Congratulations. But here's the catch. You just sacrificed all your actual CPU power to get it. The 11th gen i9 has only 8 cores compared to the 10th gen i9 which has 10 cores. It literally has fewer cores and threads. And the performance? The i9-11900K actually runs slower than the i9-10900K in many tests. Multiple benchmarks show it underperforming the 10th gen across the board. It's been called "hot garbage" and a "waste of sand". It consumes up to 30% more power than comparable 10th gen chips. And the failure rate? Over 7% which is the highest among recent Intel processors. This generation was so bad it got discontinued before the 10th gen did. So you're paying more money for less performance, more heat, more power draw, and higher chance of failure. All so you can use a PCIe 4.0 slot that barely makes a difference in real world use anyway. I've dealt with this for four years and it never got better. It runs hot, it throttles, and it's slower than the chip I had before. This is the definition of a scam. Pros: Gives you PCIe 4.0 support if your motherboard supports it. Cons: Fewer cores than 10th gen, slower performance than 10th gen in many tests, up to 30% more power draw, runs hotter, highest failure rate of any recent Intel CPU, discontinued before 10th gen, worse multithreaded performance, you lose CPU power just to get a faster slot that doesn't matter, complete waste of money, literally a downgrade disguised as an upgrade, and I've suffered with it for four years.
