Optimal GPU Radiator Position

[Oliv.r]

The setup will be PCIE to Rear fan. 1080Ti FTW3 Hybrid

What are your specs?

@WoodenMarker I don't know why it matters but its a 4790k/z97 combo in a NZXT H440 Case

If you can fit it in the rear as exhaust, that would probably be optimal. The front and top of the case is very restrictive and which wouldn't be good for mounting the rad. The top panel is also pretty bad for exhaust so having the rad as a rear intake would probably trap heat.

What cpu cooler are you using?

NZXT X61 Cooler at top & stock tri-120mm fan in front. How about the Hybrid GPU's tubing position? Should the tubes run from the top of the rad or the bottom.

Rad orientation is always best to have the Inlet and outlet up to, this helps with removign air from the system.

 

If its a closed AIO, it really doesnt matter.

I would put it at the bottom, so gravity can help the water go back. Also it looks better imo.

very common misconception.

 

An easy way to think of how it works is this. The weight of the water on one side is equivalent to the weight on the other, as such you do not needloads of power to 'push' the water up as the flow going 'down' effecivly pulls and pushes on the water going 'up' with the same force. The pump there for is effectivly pumping water as if it as on a level surface, the pressure required is only that neccesery to deal with flow resriction of the tubing, block and rad.

 

Now if the water source was at the bottom, the pump next to it, and the outflow up high, with no return. THEN you need good head pressure to get the water up.

 

I hope that helps explain it, im not that great at explaining these kinda things

Go with whichever is easier to cable manage.
