verticle vs horizontal?

post #1 of 5
Thread Starter 
Im sure that we are so over powering these issues with modern pumps.. so this is probably theory more than application
that said..
Does running radiators and other lines horizontally create a lower dynamic weight/ power usage compared to running systems horizontally... again
I know that we are in a theoretical as our loops and power are so small/ large.. ie large power small loops that the ? holds little real application in computer cooling.. more of a just interested tyoe question.. thanks

Water cooling loops are closed loop systems. Gravity has no effect at all.
What is lost going up is gained coming back down.

This.

However there is one thing with water cooling radiators which you need to keep in mind - their flow pattern.

Radiators are made of essentially a U shaped channel - water comes in one port, flows to the opposite end, turns round and flows back to the other port. If you position your radiator horizontally there is no problem, but if you position it vertically with the ports at the bottom you can have problems with air getting trapped in the end.

Usually you can shift this by moving the case round with the pump running, however it does make bleeding the loop a lot harder.

It really doesn't matter as your loop is indeed a loop. Any water being pulled down by gravity has an equal amount of gravity being pulled down in the opposite direction bringing it into equilibrium. When you turn on your pump this means, as previously stated, any force lost pushing liquid up is gained as the same amount of force is gained pulling it back down.


The only practical application is for bleeding your loop, as GingerJohn said. Air will always try to float above water, so if your radiator is positioned in a way so floating means it get's trapped then you will have a performance drop if there is air trapped in the radiator.

Alphacool makes threads on the far end of their rads for just this reason, making it easier to bleed.
