This just in from Hot Hardware fan and Super Cooling Freak-Man Steve Croft!
7.) 40mm fan mounted on back of pcb blowing onto reverse side of the cpu, (helps a lot)
8.) The 'Blue' top of the 'Olga' style cpu was found to be domed, this was machined flat, ((Note*** this is not for the faint hearted). The phase-change type pad on Tennmax cooler was removed, the area under this pad was highly polished. Thermapath white paste was used to mate the two together. That was more or less it :) I do have good cooling on this PC, which has now been running at 645MHz for 5 days, usually all day. (look at shot above for the "ground-down" CPU!)
9.) Running MBM 4.07, the cpu diode temp is around 50/51c at an ambient of 21c, whilst running SETI@Home FFT prog. Before the 'Blue-Top' was ground down, these figures would have been 10c higher approx, so although it 'Looks' crazy machining the Blue top down, it works very well, I attempted this in the full knowledge that I could screw up the cpu big time, but I can't resist a challenge :) As it happens it was much easier than I imagined. I think the blue dome maybe there to stop overclocking???? So lets get rid of it :)
