MCP 655 vs. 355

post #1 of 3
Thread Starter 
I'm looking to get a new WC'ing loop when I upgrade my machine in its entirety. I'm going to be using a single GPU block, a GTX 480 rad, and a CPU block (along with a res obviously). My question is, which pump would suit my needs more? I've heard of 355s having better head pressure which is better for certain applications, and they can also attach directly to a res without tubing (can't the 655 do that as well?). But as for the most reliable flow, which is the better move?

Thanks guys!

655 is a great buy. its relatively quieter than the 355. and the difference is not noticeable as far as performance goes in such a non restrictive loop.

655 has a higher flow where the 355 has a better head pressure. My loop is far more restrictive and the 655 is still pumping strong. Also the 655 is water Cooled as well so no need to worry about them.
