Intel Core i9-11900K Desktop Processor 8 Cores up to 5.3 GHz Unlocked LGA1200 (Intel 500 Series & Select 400 Series Chipset) 125W

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!

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

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!

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.

Great process and never had any trouble.

Funciona perfectamente con una tarjeta gráfica 4060ti y necesita refrigeración

After over five years of nearly-daily use, my 11900K finally gave up the ghost. It was a beast. I loved it. Tasked primarily with development tools (Visual Studio, etc.) and MMORPG video games, it was put through its paces many, *many* hours. About a year before it had its last hurrah it starting booting up oddly. Red LED on the Strix z590-I motherboard is basically a dead-CPU-power indicator. I eventually replaced the PS, then the motherboard, sadly to no avail. It was the CPU. Best guess is fried VR point on the silicon. Just.. wouldn't power up. <sadface> I replaced it with an 11900F. I don't really overclock, and I still have my Nvidia RTX 3800 FE that I landed by miracle during the madness of 2020-2022. So, I didn't need the integrated video. That said, I strongly recommend this CPU if you can find a quality unit these days. They clock at wonderful speeds, have great burst. And PCIe 4.0 support is a game changer. There's a reason these things still go for a price comparable to new; they're that good.

If seen too many of these new i9's and i7's put in b550 boards or anything with an LGA 1200 slot and its a waste! This is the newest of the new guys, if you get this cpu do it proper, if youre not gonna shoot for utilizing its capabilities then get a 10th gen and save money. Youre gonna need a new board, water cool this thing, gen 4 nvme drive, new 30 series gpu's (cause they utilize gen 4 pci-e slots) heres a simple breakdown of a good starting point when getting this cpu: Step 1: get an 11th gen processor (this i9 if its in your budget) Step 2: get a motherboard with gen 4 pcie slots (z590-e was my go to) Step 3: obviously water cool this unlocked beauty cause it'd be a shame not to get it to 5.3ghz (done safely with corsair's H150i elite capellix; hovers around 40's in degrees Celsius) Step 4: get a gen 4 nvme solid slate drive (might as well go samsung 980 pro for the 7000mb/s reads) Step 5: enjoy windows booting and being able to start opening webpages and games within 5 seconds of pressing the power button and never waiting for anything to load ever again 🙌🙏 ⚡ This is the future ⚡

ENG : If you know how to properly overclock it you can run at 5ghz with air colled I got 40 on idle and 49 on heavy loads. Does is better than 12th gen? For now yes, but why? Only because the 12th does a lot more heat and energy consumption and it's not stable for the moment. FR: Bon cpu tu peut l'overclock à 5ghz manuellement et surement plus.A cette vitesse j'ai 40 degré en idle et 49 en loads. Est-ce sait mieux que le I9-12900k? Oui car la 12th gen est pas encore stable.Donc avec la 12th gen vous consommer plus d'énergie donc vous aller roulez plus chaud sans compter les bugs actuel 😀

Como siempre Intel perfecto

Processor works like intended even after reusing it for my Homelab it works perfect.

Sono contenta il processore è fantastico funziona benissimo ed è arrivato prima della data stabilita venditore serio

Very good, working so well 👏
