What is the best CPU fan available? I have been looking at the Thermaltake chrome orb. It is for my current system (sig). My computer idles at 122F. That is kind-of warm, seeing as I don't overclock it. I have heard about some fans not being good for the Socket A, because of the size might crack the CPU. Is the chrome orb one of them? I thought it was the gold orb, but I'm not sure. Just thought I would make sure before I try and install it. (cracking my CPU would suck)
