setting up a loop for my gpu's. i have a swiftech dual 120mm rad, laying around and an extra res. all i need is a pump.

was thinking-
mcp350 or mcp655 which would be better? noise is of no issue to me. and any other brand suggestions are appreciated.

I have one 355 powering an entire loop with an ek v2 top.. very happy with it.

i have a mcp655 powering my cpu and nb on a pa 120.3 rad. but i'm just too lazy to tear it down and redo to get my gpu's in the loop, just less hassle to set up a second loop.

Go with the 350 and mod it into a 355 , quite easy! + alot cheaper then a 655..

350's are 3.1's. Post #10 in your link shows the new PCB in the top pic and the old modifiable PCB in the bottom pic. The extra contact pads on the newer PCB's may be for PWM though that hasn't been 100% confirmed yet. The PCB and wire connections are the same for both 3.1's and 3.25's, the only things that differ are about 11 resistors on the PCB for what I could tell ripping both pumps apart here (http://www.xtremesystems.org/forums/showthread.php?t=245795).
