MCP 35X vs. MCP655 with PWM? - Page 6

I know if I can push some more head in my system I'll have better temps, as my loop is REALLY restrictive.

Pretty sure that's most people's mentality. I don't know what your system is, but what is making your loop so restrictive?

I have 3 rads, 2 GPU blocks, CPU block, VRM block, Chipset block, many feet of copper, and some 90 degree fittings and 180 degree bends. The D5 performs just as well as my PMP-500. I prefer the PMP in the rig purely for expandability but the D5 is no slouch.

Mayhems Biocide extreme already has anti-corrosion additives, and anti scaling additives.

MCP655-PMW Flow rate is 396.3 and the head pressure is 12.13

So with the MCP655-PMW you get a lot more flow...

You answered your own question, the MCP35X provides more head pressure.

Maximum (i.e. unrestricted) flow rate is an absolutely meaningless metric for this hobby since all of our loops have restriction.

In an actual loop, an MCP35X at its maximum setting will net you higher flow rates.

The way I have my tubing setup. Nothing I can do to change it because I have an externally mounted RAD. My GPUs are in parallel as well. You should see how "ghetto" my current setup is rigged up, since I didn't have the time to bother waiting for new tubing, fittings and proper pump top as I needed this system to be UP asap after a pump failure almost took out my CPU only loop.
