I may have to use a chiller to reach my cooling goals so in an effort to avoid condensation but simplify the process I propose the following:
Speedfan reads my MB sensor (It's located down by my second PCIE slot, the coolest part of my case) and it is always a couple of degrees higher than ambient (usually about 2-5C higher than ambient). Speedfan can also control fans based upon a set temp sensor, as I am sure you all know. What I was wondering is if it is possible to use motherboard PWM function via speed fan, to a relay to provide power, then to a dual TEC chiller setup.
Through trial and error I could build a ramp for the PWM control in speedfan to keep the CPU within 5c of the MB temp sensor. I do understand that the water temp will be well below ambient at this point, so the need to insulate the tubing, reservoir, pump, fittings, and blocks will be there, but I am hoping to avoid gluing a bunch of crap to the motherboard.
Basically my knowledge gap, is if running a PWM to a relay on one side, and powering the TECs of the relay with the load power coming from a PSU is viable or will it just slam the relay open and closed too often/fast?
