The best way to solve your problem is to characterize the system. Find out where the heat is and so on.

What's are the water temps in the hot side (pre-MCW452 and post-MCW452)? What are the water temps in the cold side (pre-MCW452 and post-MCW-452)? What are the voltages actually being fed into the TECs (look for voltage sag)?

Once you do that, you can see whether the hot side is being kept cold enough and whether the problem is just too much heat or whether it is insufficient voltage or if it is insufficient flow, etc...
