Well, I figured this has surely been discussed somewhere in depth, but my searchfu must be weak, because when I searched "355" here I didn't find too much.
I'm looking to build a second water-cooled computer, and I'm not sure which of these two pumps would be best suited. I currently run an MCP-655 in my main computer, and it seems to do well. It's currently running the following loop: MCP-655 -> Storm -> Low-Profile Maze4 -> PA120.3 -> Res. The pump is located above the radiator and below the res, for what it's worth. I'm running Masterkleer 7/16" tubing and everything has 1/2" barbs stock.
Before that it was running the same loop, but with two low-profile Maze4's. I still had the IHS on my Opty at the time, so I really can't say how much only running one card has helped the temps in the loop since I removed the IHS at the same time I got rid of SLI.
Now, if I hadn't come back here to read up a little more, I probably would've just snagged another 655, but the 355's smaller form factor and the "Water Cooling Round-Up" thread got my attention. In that thread, it mentions the 655 as having better free flow, but maybe being better for single block systems. It says the 355 has low free flow (which can be improved with aftermarket tops, but will that get it up to the 655's flow abilities?), but better pressure, along with a blurb about it being good for multi-block systems.
With my current system, do you think the MCP-355 would perform better than my current MCP-655? I doubt it would be worth upgrading over, but since I'm looking to build a second WC'd rig for the wife, I figured I could either buy her all new stuff and keep mine, or buy me new stuff and move over the other stuff I'm not using to hers.
When I build the second rig, I'll be using a PA120 (not sure if I'll use the 120.2 or 120.3 yet), a Swiftech Micro Res, my leftover low profile Maze4 for the GPU, and an Apogee GT. The fans on all my rads are 120mm Coolermaster Silent LED fans in a push-pull config.
Should I get another 655, or will the 355 do better in these two-block loops? Or is it really a toss up by a degree or two either way and you'd just go for whichever was cheapest at the time?
