This will depend on the total heat dump by your watercooling loop into this 'cold' chamber or slush box setup.
Depending on heat watt dump total...this might not put a dent in what you want to cool. I could see this only working for a CPU-only loop.
Well thats all I am planning to cool. If I cooled the GPU also then I would need 6 TEC's instead.
Of course the radiator won't dissipate all the heat from the cpu into the chill box so technically the TEC
s will be even easier to cool because of this.
The only problem I see is the water freezing when the PC is in idle. Of course I will use mineral oil instead of water giving me a freezing point -30 C.
Also I didn't put in the diagram but I will also have a small aquarium pump I have just for the liquid to move around and not get hot spots.
Of course I am using a good 240 mm radiator so the liquid will be in the chiller longer.
Its a wattage game and there is more cooling power here than the cpu even puts out at load so of course this setup will drop cpu temps greatly.
Also my cpu creates 125 watts of heat and my liquid cooling loop keeps my cpu at usually 10 degrees Celsius above ambient. So my loop does transfer most of the heat and of course with the liquid in the loop going to be cooled then I expect below ambient.
I am keeping my graphics cards with air cooling so they can blow their hot air all through the case which will get rid of any condensation if there is any.
