[Area 51]

My cooling is in a constant state of flux - well, more a constant state of planning!!!

Basically, I'm headed for 4 GPUs, but I wanted to cool each GPU on its on loop so I had massive redundancy and I would be able to upgrade the GPUs in the future without having to re-engineer the whole setup (hence only 2 GPUs on wc atm). Its slightly more expensive than using 1 or 2 loops conventional design would suggest, but it has distinct advantages.

For each loop, I use:

1 x Aqua Computer block
1 x 150mm phobya reseroir
1 x 240mm phobta radiator
1 x 240mm phobya rad' stand
4 x Fractral Designs 120mm fans (set up as push pull config)
4 x fan grilles
1 x phobya DC12 400 pump
1.5 m tubing
8 x plug 'n' cool eblows
PC Ice coolant
misc scews, nuts and bolts!!!!

This setup allows me to run a pump at just 30% to keep a GPU at about 45 degrees under full load. Overall, the setup is very quiet for its ouput. I think there's a little more headroom in the GPUs for further overclocking, as the temps are rock stable and the PG GPU app is a little better behaved than the SETI one. Each pair of loops uses an M cubed T Balancer controller to control pump load (not many fan controllers can do 2 x 20W)! The radiators and resevoirs live on the outside/top of the case, and the pumps occupy the 5.25 bay.

Right now, even if I could find the cash to setup a third loop, I have run out of real-estate on/in my case for the rad', pump and res', so the next stage will be a (much) bigger case! The current setup should comeout at close to 600k/day with the 1090 in place, and maybe a further 10% more after futher GPU oc'ing!

Can't say enough good things about plug 'n' cool fittings, just cut the tube push it into the fitting and you're done - brilliant bit of engineering!!!!

My cooling concerns tend to surround my houses' inability to loose heat since it has a lot of insulation. I'm finishing off a new study atm, which is bigger and beter positioned in the house for running this rig 24x7, so hopefully I will be in a position to expand its processing capacity fairly soon.
