Tower HS Question

[photonblaster]

Searched this for an hour did not find any info. I am configuring my first OC system, and being a scientist I am doing my research first.

 

Tall HS with heat pipes will end up with some of the heat pipes having the tip lower than the CPU block. This seems counter intuitive since the liguid inside is supposed to vaporize, rise to the cooling fins where it condenses and falls back down to the block touching the CPU.

 

Has anyone run tests where the case is turned on its side so that the heat sink fins are above the CPU rather than horizontal in classic tower configuration? Does the CPU run cooler?

Here are a few links:

Mounting a CPU Cooler? The Heatpipe Direction Might Matter

Some info on heatpipes

 

 

As far as I'm concerned there will only be a 3-4C difference no matter how you mount them...

thanks for the links.

I fogot about the capilary action which can "flow up hill".

The first link you gave me ran tests in different orientations with no more than 1- 1/4 degree C difference. The author gave no indication that this small difference could be due entirely to experimental error: however it can easily explained by a 5% difference in thermal impedence of the thermal paste due to thickness/uniformity varuations

 

So probably at most a couple of deg difference regardless of tower geometry as you suggested.

 

I won't worry about it.
