Altho this chip is hot I got a MSI carbon ek with the monoblock and it keeps it cool. Runs about %10 faster then my 9900kf at 5.2ghz all core. I do a lot of emulating and gaming so this is perfect for me. I was going to get 12900k but I don't need extra cores yet and I'm happy for the price z590 way cheaper then z690. AVX 512 won't get disabled as I want that for PS3 emulating. After over a months use I would not recommend this cpu if you like to OC. This cpu can't do 5.1ghz all core even on 1.4 volt and it gets over 100c on the cores lololol... But it will run 5.1 all core and 5.3 on 2 cores.. this cpu hate manual overclocking. Single and dual threaded apps and games run at 5.3 I like that but it's still hot I wish It was delidable. Update. Ok so I got concerned ... MoreAltho this chip is hot I got a MSI carbon ek with the monoblock and it keeps it cool. Runs about %10 faster then my 9900kf at 5.2ghz all core.

Single and dual threaded apps and games run at 5.3 I like that but it's still hot I wish It was delidable. Update. Ok so I got concerned about my core temps so I decided to pull apart my whole system just to see what was up. I used the CPU past from the EK mono block and the cpu was fully covered however the CPU socket locking mechanism was a bit loose... I cleaned up the EK paste and tighten the cpu socket on the MSI MB and I used liquid metal on the IHS. Wow what a difference. I am able to hit 5.2ghz at 1.36 volt on LLC 4 fully loaded temps max temps 60-80C I'm seeing 20C lower temps and now this chip is about %15 faster than my = clocked 9900kf but it takes 1.42 volt. Never had a loose cpu socket ever and I almost sent these parts back. This cpu is now -$100 so it's a damn good deal my problem was the MB was faulty. This 11900kf at 5.2ghz -2avx DDR 4800mhz all the cores temps line up so I am super happy now my system is runny a bit faster and much cooler. Another update. Running 4.8ghz all core 1.35 volt -0 avx pulling about 200watts max load. At 5.2ghz -0 avx max load 360watts LOL!!! Also just upgraded to Samsung B die dual rank 32gb ddr4 3600 at 15-15-15-35.

I installed the CPU in my computer, previously i owned an i7 3930k, i can already notice a huge difference in rendering/processing and load times, im very happy with this purchase, if your budget is 500ish for a CPU, definitely go for it, you will not regret your decision. It is worth every penny !!!

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 ... MoreIf 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 future ?

Not sure why there are so few reviews for this product. Also not sure why it's listed under motherboards. It's an amazing cpu for gaming and lightly-threaded workloads. Don't listen to reviews about it not working or being too hot, people are just bad mounting coolers and making sure the socket fits.

Works as expected, quite hot though

I'd seen that these were hot CPUs but I didn't appreciate how hot. Intel really needs to get TDP under control.
