Hi, I've recently purchased a new computer and the cpu cooler is set at a high speed constantly. I tried lowering the fan speed in the bios with no luck and speedfan didn't work either. I proceeded to open up my case and found that the wire coming from the cpu cooler attached to the motherboard like this... After a bit of research I've discovered that I need that fourth pin to control my fan speed. My question is, is there some sort of adaptor I can purchase or another location that I can plug my cpu cooler in to so that it would enable me to control my fan speed because at the moment it is annoyingly loud. Thank you.
