I took some of your suggestions into consideration last night and I think I'm making progress. I tightened the bolts on my maze 2 and much to my surprise found that they had a lot more love to give, i.e. they tightened up quite a bit more and I thought I already had them pretty tight. I then put a neoprene shim around the outside edges of the cold plate and also around the socket itself. I also replaced my generic heatsink paste with some artic silver between the cpu and cold plate. I haven't replaced the paste between the peltiers yet, but it is on my to do list.

Results after doing these simple tweaks were 13 degrees CPU temp and 35 degrees system temp. So the system temp stayed pretty much the same while the cpu temp dropped a good 10 degrees C. I did notice that the cpu temp would hit a low of about 8 degrees C and then slowly climb up to 13 degrees where it would stabalize which suggests to me either the pump is adding to the heat after its been on a while or the radiator is being overloaded. I'll have to put my thinking cap on for this one. But either way, this weekend, I plan to rework my plumbing. When I first layed out the water flow it seemed logical to me to have the pump feeding directly into the water block, but the more I've played around with it the more it seems like a bad idea to me.

Anyway, I did check the voltage coming out of the power supplies with a voltmeter. It fluctuates between 20.45 and 20.55 volts. Without the peltiers connected the voltage is about 23.85, so is a 3-4 V drop a bad thing?

I will give the simple frost test a try tonight and check my peltier configuration. I am really going to give myself a good kicking if I got it wrong b/c I tried to be extremely careful about orienting them the right way.

Thanks for the help!
