I won a heatsink for CPU at a local Lan tournament the other day in a raffle. It's an Igloo 5710 PWM. I went into my Bios and changed it to PWM fan control, however, I don't know how to adjust the fan speeds. I've been looking around google and I haven't really found anything that makes any sense of this for me. Basically, I want to know how I adjust my fan speed on the heatsink.
