Specs on AMD's Cool'n'Quiet
The skinny of the problem is my new 64-bit Sempron 3000+ supports it but the AMD supplied CPU fan only has three pins. To enable variable speed fan in BIOS I need four pins. So I really only have half of Cool'n'Quiet working, the frequency scaling between 1GHz and 1.8GHz. I already have variable speed fans in PSU and front of case (self-controlled via temp sensors). If I could just get the CPU fan to slow down would truly be a quiet PC.
Right now it's only cool.
Anyone know where I can get one without buying another boxed AMD CPU? Apparently they're included with the more expensive processors. I just didn't get one with my Sempron.
I searched ebay for replacement heasink/fan combos and none claimed compliance with AMD's spec.
