I have an idea, why not just put half a metre of fins at the base of my CPU cooler and have heatpipes at the top! See how that performs...
Notice that on the NB heatsink, the heatpipe is positioned low down, near the base where it is hottest. Heat is transferred to the fluid in the heatpipe.
Now look at the MOSFET sink where the heatpipe is positioned at the tip of the fins. Heat is being transferred from the heatpipe to the MOSFET sink.
If the heatpipe where closer to the base of the MOSFET sink, once the MOSFETS produced enough heat, the heatpipe could start transferring heat to the NB, which we do not want! The NB has a lower max operating temperature than MOSFETs do, and even then, MOSFETs shouldn't be running excessively hot (If they are, some static charged kid has fried the gate on them!).
But then again, what do I know, I've only been studying the theory behind this sort of stuff for the last 3 years of my academic career...Edited by alk - 8/13/09 at 3:46am
