Measuring Heatpipe Efficiency - mCubed Heat Pipe Extension

A new contributor reports on his efforts to determine the heat transfer efficiency of the Borg 6mm HES (Heatpipe Extension Set) by mCubed, designed for use in their passive home theather PC cases. The author's aim is to design a secondary system to aid a 1U HSF in cooling the CPU in an extremely low profile media PC case. He created a testing rig that's worthy of the SPCR lab, one that allows the thermal loss factor of this heatpipe system to be easily seen. The results are applicable mostly to the mCube heatpipes and mounting system but also gives insight into the kind of results that can be expected from DIY heatpipe setups.
