OK, I popped on Rivatuner and am editing the fan speedvia Target Adapter > Customize > Low-level system tweaks. I noticed you could do it in a different method but this seemed simplest.
Question: Is the fan speed a static 40% by default regardless of temps? I noticed at 80% it got quite a bit louder, and was wondering if it raised automatically and I never noticed it before, or if it was indeed always 40%.
I put it on 65%, I'll see how that turns out.
