What's the best possible cooling solution for home mining?

I just tried yesterday on one of the 5870 cards to use a simple GPU block to water cool the GPU and use RAM sinks and a big low rpm fan to cool the VRM

But there are problems: After one hour, the radiator of the water cooling device start to get hot, and GPU temp rise from 40 degree to 53 degree, means the water temp at least rised by 13 degree.

This is only one GPU, if 2-3 GPU burns at the same time, I'm afraid the radiator will not be cool enough to keep the GPU temp down. Another problem is the VRM temps got really high (80+) and are at least 20 degree higher than the stock fan cooler, seems the only way to cool the VRM correct is to install a customized VRM sink like those from vf3000a

After this experiment, I simply installed back the stock cooler and try to tolerate the noise instead. I think the best way is to put the whole machine in the balcony (less than 25 degree most of the time, minus 10 during winter), but that will put lots of requirement on the casing design

Is there any one using watercooling here, how many cards a watercooling device can handle? Any other solutions which works better?

best?

kinda expensive though...

Looks great, how that smells? 

It may not handle the heat of 4+ cards, and the heat will raise the temp in the room, either radiator has to be put outside the room or the whole machine has to be put in a cold environment

it should handle four 5870s just fine - they tested that one with two 5990s, as i recall.

dunno what it smells like - but it's pure mineral oil, not fry grease. 

i think i saw a window bracket you can get - if not, it shouldn't be too tough to cobble one together.  but yeah - not much point to it if you don't put the radiator outside.

that site is like crack.  i'll have to get one of those suckers, sometime...

I just fixed my car AC the other day, super simple, a can of r134a and I got cold air right away. Why there is still no AC case (or even AC cooling set for cpu/gpu/vrm) available? Is it regulated? I only find one similar case using semiconductor material and it lowered the case temperature by a miserable 3 degree...
