I just installed my new Phenom II X6 1090T. It's the first CPU I installed in a while. Perhaps the last one was the Celeron 300A, and that came on a card. Anyway, seemed simple enough, especially after watching a YouTube video (and the start of another which luckily reminded me to upgrade the BIOS). Of course, I have no idea if I did everything correctly, but the PC at least works.

Problem is the fan noise. It's just terrible. I ran Overdrive and it says that FAN0, which I guess is the CPU fan, is running at around 5400rpm. Temperature is 51C for that fan (room temperature is 32C). CPU usage is at around 17%, which isn't idle, but it's not even close to load. Cool & Quiet is enabled.

So the first question is, did I do anything wrong? Did I mess up the thermal paste by moving it, dust got in the way, that kind of thing. I mean, is it normal temperature to be 19C over room temp with a slight load?

Second is, is it possible to undervolt the non-load voltage? I underclocked and undervolted in Overdrive, but that only reduces the voltage when the cores are at max. Most of the time they're at 2400MHz and voltage goes to 1.325, which is more than I set.

It's a real pity that I can't just put the old CPU back in, because I'll need to reapply thermal past which I don't have.

Anyway I guess I'll start looking for aftermarket coolers. Never used them, but this noise is completely driving me nuts.
