I use water cooling, strapped to the copper-pipe going into my hot-water tank and sprinkers and tapped into my pool-pump/hot-tub...
Free hot water, lower AC bills, lower electric bills (higher heat = higher resistance = more power consumed)...
Not to mention the hot air is all pumped into the attic, where the 150F GPU air is cooler than the 212F+ attic-air.
That is called ghetto geo-thermal cooling... lol... the cool water coming from underground is a constant 65F here. And I drink coffee all day long, and flush, and shower, and filter the pool, so cooling isn't lacking.
Hi Isawhim,
I think your concept is great. I actually believe that the future of mining (especially on GPUs) is dependant on our ability to recycle some of the heat lost.
I'm working on a new 24 GPU rack project (
https://bitcointalk.org/index.php?topic=191117.0) and I will experiment with oil cooling in a few weeks. You can find details about the oil cooling option here:
https://forum.litecoin.net/index.php/topic,2682.msg18234.html#msg18234My idea to optimize the heat recycling is to use an Oil/Water plate heat exchanger, which is very efficient and compact.

If you had the pool (which will "never" go over 40C) you can truly reduce your electricity bill by a considerable amount by never having to warm it up again.
I started a list of potential applications that would allow for the recycling of the heat:
If you think about it, if we could recycle 80% of what's now lost, there would not be that much interest in the ASIC anymore.
Maybe I should sell the 24 GPU rack as a space/water heater ;-)
