Exclamation Heat pipe efficiency

I have a Kama Angle cooler on my i7-920 CPU. It is in a tower case and appearts to be working. At least it is keeping the CPU temperature under load to approx. 69°C-70°C.

My question is a technical one. The Kama Angle has four heat pipes. What is keeping the fluid in the heat pipes at the CPU heat spreader location?
I have always thought a fliud would flow to it lowest point. When the Kama angle is mounted on the CPU in a tower, four ends of the pipes are below the CPU heat spreader and four are above it.

Would the Kama Angle be more efficient if the tower were laid on its side?

I really would like it expalined. Right now, magic is all I can think of as an answer.

Hi,

The flow inside a pipe is a little bit different: more here: Heat pipe - Wikipedia, the free encyclopedia

But what i can say, the best position for Kama Angle is: one side to rear fan (horizontal to the left) and one side to PSU (vertical to the top). Thats the physicaly best position for this cooler.

Cheers Chris

Very interesting reading. A bit disappointed though, I was really hoping it worked by magic.
My Kama Angle is mounted as you stated and certainly appears to be doing its job.

Thank you.
