i think you should stick and A meter in line to find out how may amps your TEC is drawing as we dont know right . now .. i assume your first post meant that you were using a 320watt tec @ 12 volts not that the TEC was drawing 320 watts.. ..
lets look at the facts you've given us .. cpu temp of 59 ..so the cold side is @ 59 while the hot sides water is at 33 ..
That just doesn't seem right.
The only way this is possible is
A your TEC isn't powerful enough ... which it should be
B that the C/W of your water block is very high producing a VERY high hot side temp but low ish water temp. This is possible as the maze isn't the greatest water block . this is easy to test by putting a temp monitor on you water block i dout it'll be in the 80 - 90c range..
Which leaves C .. your not applying enough pressure on the TEC to transfer all the heat into the waterblock and water .. this is relatively simple to test . by testing the the wattage used at full load then removing it from you pc and testing the relatively unloaded wattage used . if they are both close to gether you need more pressure .. obviously another test is to see if the amps used decreases as you apply more pressure to the TEC.
I do find your water temps to be a bit strange i TEC cooled my old 70watt p4 with 2 120 radiators and there is no way with my tec drawing 400watts that my water temps were 33c they got well over 60 .. however your water temps might be right given the probably pressure related issue
the only amp meter i got is 10a, so that wont help, the tec is on 12v 22a.
as for the tec pressure, i have only the pressure f the mounting bracket which is pretty tight, but my tec is 50x50, and so is my cold plate, i have no other coldplates
