[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.

Hello Area51!
I've seen you in the lists before, wondered were you were.

It sure was not the cooler of my latest GPU cruncher that was the problem -a nice heatpipe system on a Sapphire HD3850 AGP- but it drew too much power at a moment, so tomorrow I'm off to buy a new PSU, a 500W one with the meant 8-pins PCIE connector for the blasted GPU. You CAN just use the 6-pin PCIE connector, but apparantly not with a 350W FSP PSU...
The new PSU has more advantages, such as SATA connectors and the possibility to run even better GPUs from it in the future. At the moment my CPU is almost finihed with the 1058 (estimated) hour job on a seventeen-or-bust WU, which was finished in little over 210 hours actual time.
