Hi, I am trying to minimise noise at the moment, and am going to go through various steps. One is to get a fan controller to reduce rpm and noise. I have just been on the phone to Gigabyte who say the mobo fan controller only supports pwm. I am surprised, because there is an option for voltage fan control in the bios. If this is true, and it may be as my CPU cooler is running at 2000 rpm constantly, I might swap CPU cooler fan for a PWM version. I am surprised how few PWM 120mm fan there are. I did a search for the obvious first pass matches, so I am not saying there aren't others out there. The main ones which kept getting found were Artic Cooling, Nexus and Scythe. I think there was a few with less hits. Has anyone mustered the will and the motivation to change their 3 pin cpu cooler to a pwm fan? I must say, taking the mobo out, removing the heatsink, cleaning the compound off, remounting and replacing is looking like a big chore at the moment.
