Please help me understand heat pipe technology and orientation

TLDR: is it OK to have a heat pipe mounted sideways instead of vertical? Would it still work, would it work properly?

Long version: Hello everyone. I purchased all of the pc components already except for the heatsink and fan combo. I am currently looking at "Zalman CNPS9500" to toss onto my CPU. I do not understand if orientation is important because the product has heat-pipes. From my understanding the liquid inside the heat pipe turns into gas, gas then floats up because gas is lighter than liquid, then gas cools with the assistance of a fan, cold gas then turns back to liquid and then floats down inside the heat pipe to repeat the cycle. I have a pc case that is a tower. So the gas will not be evaporating from the bottom to the top, it will be evaporating sideways? Would it work? would it work efficiently? Is it OK to have a sideways mounted heatsink or should I lay my PC case on its side so that heat pipe is properly oriented from top to bottom? Is there such a thing as "proper orientation" for modern heat pipes?  Thanks a lot in advance to anyone who shares their wisdom with me!

I can't say exactly how it works, but the standard heatpipes in PC coolers are not at all affected by gravity or the orientation.
