Re: Yep, another Cube!
Well, today has been not a laser day but a day to check if I can get passive cooling working in the orignal manner.
As I write this I have my CPU (a C2D E7400 2.8GHz chip) of my Zotac fixed to the Cube heatsink and I am running a handbrake encode of a movie while carefully watching iStat Pro to see what happens. This is very scary, I am about 20 minutes into the encode and the temps have risen slowly but steadily and are now at 62 and 60 for the two cores. The G5 heatsink is warm to the touch.
Here are some photos of the experimental heatsink rig:

The first photo is part of a kit from HFX that is usually used with heatpipes etc. I figured I had not enough room to twist heat pipes around so instead I looked at the gap between the top of the 40mm aluminium block and bought a chunk of 12mm alu plate and machine that as in the second pic. then I measured out where I would drill the G4 heatsink.
So the set up is:
40mm cube of alu is attached to CPU via acrylic "spring" until the acrylic only just bows a little. Then attach the 12mm plate to that. Then turn the motherboard upside down and attach the plate to the Cube heatsink using the three processor screws that the G4 had on the original. Next, very carefully becasue you do not want the whole weight of the G4 heatsink stressing the CPU or mobo put everything into the outer cage and then tighten all the screws a little. If the balance is right then the weight of the G4 heatsink is taken by the cage, and not by the CPU.......the pressure on the CPU is from the acrylic plate.
Temp.s now at 73 degrees and I'm about to throw in a geekbench run at the same time. Gulp. Will report back....
