I have a folding farm with 16 caseless p4 HT/DC (all OC'ed) rigs on open shelving in a small basement storage room. It has outside ventilation in through a 200 cfm fan.
Winter temps make it an intake. Once outside temps increase, i will switch the fan to exhaust.
I want to put together a cooling system that will let me keep my overclocks and all rigs going all summer without killing me on central air costs.
So I am thinking of a large scale (16 rig) water cooling setup.
I will already have my 920 and soon to arrive 930 on water. Am thinking i will do a bunch of homemade ghetto waterblocks for the other rigs.
I am thinking that a exterior rad/evap system is what i want to design and build. Since global warming seems to be here, i may want to supplement rad cooling with an evap and/or a chiller system.
For a chiller, i have an unused dehumidifier i was thinking would be useful. Am also thinking of using fresh cold water supply (at some trickle rate) that could be used to supply a cold source cheaply. Current cold water supply temps are a little over 40F ... am guessing should stay sub 50 F in summer.
An evap or cold water feed approach would require some kind of heat exchanger so that the cpu loops would be a closed loop, and an open loop for evap/cold water feed.
To economize on electricity, I will probably swap out a few northwoods and prescotts for fewer DC rigs. Currently all is intel and will likely stick with intel for now since it makes my farm management simpler with a fairly homogeneous set of rigs/mobos. I also expect to switch out some for Conroe rigs but likely much later in the year when prices get resonable. Possibly AMD's depending how the race plays out and their folding performance.
I am thinking that during the late spring, summer, early fall, the heat exchange will be outside the house, and i will possibly move it inside in the winter to offset heating costs.
I am just starting my research so any thoughts, links would be muchly appreciated!
