I was a bit worried about all the reviews, criticizing how this CPU can't keep up its boost frequencies over long periods of time due to excessive heat. Because of that, I specifically bought a Noctua NH-D15, because it's "the best air cooler, that can even measure with water cooler".
I let the CPU work on some raytracing app I wrote long ago. The app can put 100% load consistently on all cores.
It's been running for over 3 hours, the CPU has been clocked at 4.7 GHz (stock boost frequency for all 8 cores) this entire time without dropping even once, and the temperature is around 50-55 °C with the fans in "silent mode".
Maybe the 9900K really does get very hot, and the NH-D15 is just that good, but judging by those temps, I could try and overclock this CPU.
At stock frequencies, it vastly outperforms my old 6700K.
At least I can finally play Assassin's Creed Odyssey without constant microstuttering.
This CPU is probably not worth upgrading to for those who own the newer 7700K or 8700K, but for any who seek gaming performance, this is a pretty good CPU.…mehr
