Many CPU coolers are using these heat pipes that work on some gas law. I'm wondering if there is position the heat pipes would would work the best at. Example when the computer is sitting upright should the heat pipes be pointing horizontally away from the CPU like an 'L'? Or get a cooler where the pipes are in a U shape where they are curved up like a U or down like 'n'?

just want to know if anyone has experimented with them or know anything more about them.

The shape is irrelevant except when including it's effect on airflow throughout the case.

The shape of the cooler, and most importantly the direction of the fans on said cooler will effect how air moves in and out of the case. You want to avoid fan directions and placements that create "pockets" of air. You want to allow the air to move freely in and out (through) of the case.


The factors that most effect cooling capabilities are the amount of heat pipes, the size of the heatsink(s), and the amount and direction of fans.

I experimented around with my new laptop that uses heatpipes, the fan vent is on the back not the side. I put the laptop with cpu on top and fan on bottem and the temp raised to almost 100c. I then place the laptop with fan on top and the temps went below normal by a few degrees. So yes make sure your heat pipes/with heat sinks are either in the up or side position with of course your fan... Perhaps the best case would be a desktop case instead of a tower since the pipes will have the heat rise away from the cpu. Basically heat rises so duh...

The heat transfer within and along heat pipes is governed by the metallic properties of the heat pipe itself. It has little/nothing to do with the orientation of the pipe. The orientation of the radiator fins is another story. Natural radiation and convection current with the surround air are keys to heat transfer. The orientation of the fins should be dictated by the predominate air flow around and through the radiator.

I'm a guy that likes to gain a lot of knowledge about things, so im not doubting you just want to know more about this property of heat pipes.
