Seeking your approval on a loop plan

post #1 of 7
Thread Starter 

This is the first time putting together a water cooling rig and would appreciate any feedback. Mind the cables, not everything is hooked up yet. The GPUs plugged in are just x16 lane placeholders for when I get the real deal. Top one would be for the TV, bottom one would be for two separate 21.5" screens for productivity (with occasional HD video playback). I did it this way so the GPUs get cooled flow and then hits another radiator before cooling the CPU. I'm not quite ready to buy two new GPUs and three new screens (at least $2,400 in costs) but this is for inevitable future expansion, even though it's kind of overkill with just CPU cooling at the moment. The bottom radiator might cool better because it's much thicker and will have better fans and the top rad is thinner and will be using three stock fans. My stuff will be arriving this week.

It might not matter a whole lot, but seems counter intuitive to have the pump working against the natural gravitational flow.

And the temperatures will stabilize out anyways, doesn't really matter what order they are in. The water will hit a stable temperature and tend to stay there, you won't see dramatic temperature changes throughout the loop.

Doesn't the pump pushing that long line down to the 240 mm go with gravity? Anyway that I can see, no matter what I do, one side is going down and the other is going up. Would switching the reservoir and pump lines make a difference?

Re: stable temperatures, I realize this, but I wonder if I can make small differences in the order or if it doesn't really matter.

Sure going down that one line it's working with gravity, but the entire rest of your loop you are fighting it.

Just doesn't look right to me. Just my opinion though, not fact.


And everything I've read says loop order doesn't really matter.

Okay, how's this? The pump and reservoir are now in a radiator sandwich and the pump hits the components with gravity before returning to the reservoir. I thought about having the tubes come out of the other side of the 360, but I wonder if it'd be a pain in the ass to have all the tubing bunched together that way. I won't know for sure till my stuff gets here.

Also running your cards in parallel instead of series will cut down on your flow restriction by a good amount.

You mean have two connections between the cards like this?

EDIT: Re-fixed the picture.
