yes you could make them stop completely - you could just unplug them, but I wouldn't recommend it. the more fans you have the better, especially when your overclocking - why do you want to disable them so badly?
well you see my room now in winter is already cold enough
Id like to use 2 fans all the time and enable another 2 when im gaming.
Its all about less dB. Im reading and writing on PC.
But i suppose i cant do that automatically,right?
I've never actually tried but I know you have a certain amount of fan control in the BIOS, and on a capable P35, you should also be able to change fan settings. I think that the only way you can control fans is when they are connected to the motherboard, not to your power supply.
