i9-9900K Overclock Temps & Cooling
Passed without BSOD at 1.21v for 15 minutes. Peak reached 87C, average around 83C. Believe this is the peak performance possible with my current AIO. The only thing I’d consider changing is lowering the CPU temperature further by using a liquid cooler and switching to a 360 AIO model. My temperatures rarely approach this level during gaming or multitasking. I was just exploring how high they could get under heavy stress. I think my current 280 AIO is suitable for my needs, but it struggles when pushed to extreme limits.
Difference between a 280mm and a 360mm is capacity. A 280mm can handle @ 300w, a 360mm can handle @ 350w.
At 5.0GHz, that i9 9900k is dumping close to 250w.
Will a 360mm help? A little. And only under duress. But nothing drastic as the cpu can't output enough heat to broach limits. The biggest advantage to a 360mm is fans. There's 3 of them, so combined they'll run at lower rpm than 2x 140mm.
Capacity isn't ability. That's all on the fans. Different fans might be better (or worse) and be more effective overall.
It's an i9 9900k. At 5.0GHz locked core OC, Gaming loads under @ 85°C are decent. Full core burns like from stress tests at anything under throttle temps are acceptable. It takes a full custom loop to really tame that beast of a cpu.

is used as a temp test only. Takes about half an hour to climatize an aio for a reliable temp.
Real bench is a stability test, for when messing with OC/voltages.
