If you are having problems shifting the air I'd suggest a bigger fan - 60mm is tiny, you'll get much better results with something like a 120mm or bigger (I use a 172x55mm on my radiator and it's great).

I understand thickness and Im looking around at that now, but a larger size is problematic for the setup. since I am attempting to keep it small and compact. a larger fan like 120mm is about 5" across. then you figure 5-6" pipe to get the air out, you are at a foot wide resevior section. I dont want it that big.

80mm is pushing the size to about 8".

I am looking at the thermaltake 60mm fan, its 25mm thick and says he has a max pressure of 5.3mm-H20. double ball bearing, 21cfm, and 28dB.

theres also some vantec fans that look similair, but dont give a specific pressure.

even so, a larger fan means larger piping, means more water ect ect, should it not be all to scale? where a larger fan NEEDS more pressure?
