I've been trying to get into using Ubuntu 12.10, but it's hard when my PCs fans are nonstop running so loud I get a headache at the very least.
While it was running Windows 7 the fans were mostly quiet. I've tried all these vague guides to using lm-sensors and fancontrol but so far all that has achieved is pwmconfig increasing the speed of one fan to max and then not lowering it until I restart no matter what I blindly attempt.
All I want to do is lower the PWM/RPM.
EDIT: I managed to make just the rear fan slow down drastically. Thankfully it's the largest and loudest fan, so even if I can't get the others to slow it's a decent victory.
