I'm worried about the condensation on the CPU block because it doesn't look insulated... If the board isn't prepared for sub ambient temps I am afraid you'll find water in the CPU socket, or worse just a bunch of corrosion on the CPU pins resulting in a dead board. My last chill water setup had the later, unfortunately. I had insulation on the CPU block but no dielectric grease in the socket -- I learned the hard way. =\ After that setup I made a program to throttle the temp to 18C by controlling the COM port. Just a simple relay off the COM port to turn on 120vac to the compressor. My program would read the coretemp log and turn on or off the temp according to that. Fun stuff.


I'm excited about this rig so please don't think I'm trying to be pessimistic -- just excited to see it work well for you! Thanks for sharing the pictures, post more soon! =)
