My 1800+ T-bred is running t around 2.22ghz (212x10.5) @ 1.62 volts. The thing i'm cooling this with is a $6 GC68 and the idle temps now are around 41C. The internal die temps are around 54C idle. Also, I'm dealing with the California summer. If I do get a $20 sk7 from svc, how much of a temp difference should I see? Also, which cheap ($5 and under)fan would go good with this heatsink? Thanks for the help.
