I have two pelt enabled water blocks, a Swiftech MCW462-UHT, and an Maze4 + 1, both with 226 W peltiers (supposedly) .
The problem is that the Maze 4 is dismally performing when compared with the swifty.

I am only being able to get some 2 - 3 degrees below ambient temperature with the Maze 4, where as with the swifty can easily achieve +- 15 degrees below ambient.
One possibility is that the Maze 4 was shipped with a lower wattage peltier, SO how does one make sure that a 226W peltier is a 226W? need help on this one.
Asides from a possible underpowered peltier, privately I am beginning to think that the Maze 4 is not suitable for pelt cooling, due to the reduced water cooled area inside the water block.
Any other things I may have overlooked?
