well, PC reliability has always trump performance for me. but yesterday, i came across a brand new unit of Coolermaster Aquagate at a retail outlet i hangout. i couldn't resist and got it for $65 with everything in a big box. a bargain i think. with a couple peltiers and a waterblock sitting somewhere, i got an idea and want to run through folks with more experience working on water cooling. here's my idea: Boosting Water Cooling I intend to connect the Aquagate in a standard manner, but will hook up a second waterblock along the pipe with water flowing into the primary CPU water block. The flat surface of the secondary water block will contact with the cold side of the 18A (max) peltier device, and the hot side is connected to a redundant CPU heat sink on air, probably sticking outside the case. Peltier is probably going to be supported by a reasonable secondary PSU (single rail) to avoid bringing the whole +12v rail on the main PSU down. Are there any flaws that i haven't think of or you think is a problem? thanks.
