have not had this one on a properly rigged CPU but I can pretty much imagine it would chill the shit out of even a presshott....
proper insulation and running with antifreeze... I'd think sub zero full load on your 1700+ should be attainable without a TEC...
if you install a thermostat, it can be a real handy little gadget... I ran my chillers at about 10% Duty Cycle, mainly to save on bills... and that 10% was enough to get me very comfortably below ambient..... I stand correctable, but to me it seemed like the stretch where the returns where max is from +20 all the way down to about 0º. Anything below 0 and the returns begins to negate agains the costs of running at those temps....
my Duron600 from way back could do what it did at -3ºC taking the temp up to +15 only cost me about 50Mhz but the saving in that obviously made it very much worth my while to not run full blast all the time...
so ya.. it can be very economical, and it can be very expensive, depends on the "volume knob"...
