Left is idle, right is under full gaming load (Helldivers 2). My previous rig (Intel) easily went up to 85-90°C in the same circumstances. Ambient temps are slightly elevated as well since we’ve been having ~30°C temps daily here for a while now.
To me this is almost ridiculous. I had never dreamed I could get my temps under load under 70. CPU is at stock speed since there is literally no reason to push it any further at this point. Can always choose to up the clocks later if I still want to.
Cooler is a Noctua NH-D15 G2. I don’t see myself returning to watercooling any time soon. And Noctua has a new customer for life.
Same as others here, the concern for me was noise back when I was on an intel platform that wanted to dump 220W into the CPU. Noctua or not, you can’t run that silently even with an AIO. I ended up lowering the power limits on that just to keep noise down.
The radiator gives you more room to run more fans slower and make less noise for the same temps, which is nice.
I moved from that to a 7800X3D and that capped out at 75W, so you could cool it by blowing on it from across the room. Newer AMD CPUs are a bit more power hungry again, but it’s still nowhere near the little square of a supernova Intel used to ship. I do still use an AIO… mostly because despite some of the other comments here, I actually have a couple of old ones in working order and haven’t felt the need to change things around.
