I am completing setup of my first peltier based water cooling system and some of my initial results are not what I expected and I was hoping some of you all-powerful water cooling/peltier Jedi could set me back on the path to the light side of the force.

I've done most of the condensation prevention around the socket and I am using two 120 W peltiers @ 20 V each with an Athlon XP 1600 (1.4Ghz). My CPU temps generally stabalize at about 23 deg C. My system temp is at 32 deg C. I am not overclocking at all yet so all cpu voltages are at default. The board I am using is a Soyo Dragon Plus which should be using the thermistor built into the Athlon XP CPU and not an external thermistor so it seems like the temps should be fairly accurate.

Anyway, I was under the impression that my temps should be much, much lower that 23 degrees. Do you think it could be my water loop setup? I have the line going from the pump to the water block and then from the water block to the radiator and then back to the pump. I noticed that the Eheim 1250 I am using gets fairly warm after its been on a while so could this be keeping my water block too hot? Should I have the water coming from the radiator going straight into the water block or does the heat from the pump have a neglible effect on the heat of the water loop the way I have it? Do you think it could be a question of insulating the cold plate better? There are parts of the cold plate still exposed, but I didn't think that would matter too much (certainly not 23 degrees worth), but I could be wrong. I also have two 7200 rpm 120 mm fans blowing through the radiator (one for intake, one for exhaust), so I don't think it is lack of air movement through the radiator. Anyway, I've listed system components below for thoroghness.

Thanks for any feedback,
Immudium

My Water cooling gear is as follows:
Maze 2-2
2 120W Peltiers (ordered directly from TE Dist) @ 24V each
Super Cube radiator + two 7200 rpm fans at intake and exhaust
Eheim 1250 pump
1/2" fittings
2 X 230W power supplies in series for peltiers

Computer components:
Athlon XP 1600 (1.4GHz) @ 1.75V
Soyo Dragon+ MB
512 MB Crucial DDR
430 W Antec PS
32 MB Creative Labs GeForce vid card
