I'm very happy with how quiet my system has been even with 100% CPU taxed for days on end. But it's strange how my fans usually run at >1000rpm all the time except for my DRIVE BAY fan always stays at a constant 1000RPM. I've seen it go up a fraction to like 1004 once when I was doing a lot transfering from my old HDDs to my new ones. Is that fan supposed to fluctuate like the others or is it a constant? I've dusted out my system and made sure to clean/wipe off all the temp zone sensors too. Thanks.
