AMD Ryzen Threadripper 2nd Gen - RYZEN Threadripper 2990WX Colfax (Zen+) 32-Core, 64-Thread, 4.2 GHz Max Boost (3.0 GHz Base), Socket sTR4 250W YD299XAZAFWOF Desktop Processor

Pros: - Paired it with a Liqtech II 280 and Grizzly Kryonaut. Runs at 38-40C in "ultra quiet mode" during day to day activity and 55C under full load. In a more aggressive fan profile, I can run day to day activity at 32-35C.
- It's fast. Multi-threaded performance is great. Single threaded performance is solid as well.

Cons: - No major issues to date.
- It puts out a lot of heat under load, but I knew this would happen. On the bright side, it's a nifty space heater.

Overall Review: - For those that have heat issues and are using Arctic Silver with the AIO, you will need to step up to newer, high-end TIM such as Grizzly Kryonaut. I've used AS for my last 5 builds and attempted to use it on this build. After giving it two weeks to break-in, the CPU ran hot and routinely peaked around 72C. Kryonaut resolved the heat issues.

Pros: 2 times the amount of cores / threads of the 6850K

Cons: HOT! I use a double 240 radiator setup with four 120 fans total, always keeping the raidators cool. the old 6850K that I had used in this same water cooling setup always kept at less than 55C with a full load. The GTX 1070 never ran beyond 45C in itself.

As soon as I placed this into the loop in place of the 6850K, I immediately noticed that the temps shot up from normal 45C on the nvidia card to 52C without any kind of load. As soon as load was introduced onto card, the temps krept right up to 68C with the CPU temp soaring at over 79C!!!! 79C on a double 240 radiator setup?!?!?!?!!? Uncalled for! Especially when Kill-a-Watt is showing LESS of a power draw than the old 6850K! What's happening? Is ALL the power being turned into HEAT?!?

After figuring that it may have been the thermal compound, I took it all apart to check how the compound was squished. It looked darn near perfect. I cleaned it off and placed more Arctic Silver onto the GIGANTIC IHS again, just for good measure, then reinstalled all parts again, making sure that the waterblock was placed and torqued perfectly upon reinstallation.

Alas, after hours upon hours of work, this CPU is still running hotter than a furnace in the dead of winter.... in Alaska.

Overall Review: Unless you're coming from an older legacy generation of CPU, and ONLY if you need more cores than 8 (See Ryzen 2700X), I would not recommend this chip. At 180W TDP, this thing is enough to heat a small house.... but doesn't have the calculations to back up the price.
