Heatpipe question

post #1 of 3
Thread Starter 
This is my understanding on how it works, correct me if I'm wrong:
I know that the heat pipe work by vaporizing/condensing of the working fluid. The vapor need to flow up, then condense on the top. The condensed working fluid then flow down by the work of gravity so that it can absorb more heat again. Something that looks like this



Since computers nowadays all uses tower case. The CPU is held sideway. This makes the working fluid doesn't cover the whole CPU surface and decreasing it's efficiency. It become something like this:



What's worse is that my GPU is facing downward on my computer.



So the question is...is this really how it works?

This might help http://en.wikipedia.org/wiki/Heatpipe

I don't remember how or why but heapipes work just as well in any position.

Here's an old school link that gives good info:

I always thought the same thing, being sideways a HSF would perform worse than being mounted straight up. More of the reason to have your mobo sit outside a case on your desk.

I've been giving it some thought and I hate to say it but I might switch to air just to do a comparison between inside & outside the case temp differences. Maybe not a permanent change but if the temps are right then who knows.
