I've finished my quad 226watts Qmax TEC chiller and im currently using it to cool my PC. The construction of the chiller didn't go as well as I had hoped so this one has plenty of compromises but it still works well enough. If I ever get my CNC milling machine going I'll make a new one with no compromises. This Chiller is controlled by a TEC booster that I made for the T-balancer and it works great. The booster enables me to keep the water at X temp irrelevant of hot side temp or load. This means when the PC is idling im saving power and in winter I should be also saving power over a normal TEC build which runs at 100% all the time.
