I got a S260CP from natex. When I first started using it, I left it with whatever settings they had it on, which worked fine. After doing FRUSDR the fans were very quiet. I finally got a video card (GTX 950) and have been trying to get kvm with GPU passthrough working. In the process I got into a configuration where I couldn't see the BIOS screen because the display was off, so I did a CMOS reset. I re-ran FRUSDR (not actually sure if that was necessary, does CMOS reset rollback the BIOS?), but the fans are much louder after booting now. They start out pretty quiet, but slowly ramp up and then stay at a higher level. Definitely audible whereas before they were almost silent all the time. Any ideas what settings I might need to change? In the BIOS I have it set to Acoustic mode.
