Editorial Review This fans default setting is on full speed, which is obviously the loudest setting. With the proper PWM control working, you won't likely experience full speed very often. If you aren't familiar with how the PWM function works, you might want to google it and make sure your bios supports it or you may experience louder than optimal noise levels
