I've been reading about AMD's Cool'n'Quiet™ Technology - some websites stated it was "crap" and other said "cool" (in the very meaing of the word! :-) technology. So, I decided to give it a go, since I'm the lucky and *very* satisfied owner of an AMD 64 X2 3800+ DualCore CPU. I've been using it for some days now and I can only say: It works!! .. the CPU is as quick as ever and my PC is now even more quiet than it was before! So - Go ahead and read the Install Manual and be sure to install the AMDs "Power Monitor" utility which is great (above image!)
