New idea, check my math before I drill...

[Kayin]

OK, so I had a (hopefully) bright idea concerning my GPU setup in Mithril...

The GPUs are on a siamesed reservoir, total capacity is over 1 gallon. The proposed tubing routing setup is res-pump-rad-GPU-res, so as to get the coolest water available.

What this gives me is a "hot" reservoir, as 2 4870x2s is a significant heat dump, and with OCing and vmodding that's a lot of extra heat. While an MCR320 per card is a lot of cooling, I had the idea for a "recirculator" loop, consisting of a pump and a BIX 120 I have lying around, that would simply function to cool down the reservoir and lower overall system temps.

It would simply be a second set of holes drilled in my reservoir, with a second set of 3/8" barbs (or 1/2", I have a lot of those lying around,) a pump and the rad, no blocks in loop. By placing it above the pickup holes, falling cool water would be picked up by the pumps, adding to the cooling overall.

Am I nuts, or do I have some kind of idea?

if you have the space for it, and the willingness when maintenance time comes, then go for it...

i think it would make more sense to just add the extra rad and pump in series in your loop... that way your blocks get the benefit of the added pressure.

I agree with Ballzor, add the 120 rad into your GPU loop.

That said I think the idea of cooling the Res is great, but you would want to make sure you don't cause some kind of weird flow problems in your res.

[ballz0r]

it would be cool to try putting all your rads on a separate loop with your blocks on the other joined by a common res

this would probably result in the maximum flow rate to your blocks because the pressure drop would be small

[Baleful]

I say go for it!

[Snyxxx]

I think it is interesting. I wonder if the hot water would not want to flow directly into the pump and bypass the res cooling loop?

Maybe I need to see a sketch to completely understand.

[Kayin]

I'll photograph everything tonight and do some diagramming.

I've made it sound so horribly complicated, but maybe it is...

[cheapskate]

I like the radiator loop idea Ballzor proposed. I think that would work well with your 'fishtank' reservoir.

[Septim]

probably depends on internal waterflow inside the tank, and the inlet and outlet hole placements...
