Change out MCP355 for MCP350? Or keep XSPC X2O 750?

post #1 of 8
Thread Starter 
Recently bought an MCP355 + XSPC Dual Bay Reservoir for single DDC pumps, and I realized that an MCP355 is way too strong for a low restriction CPU only loop, which would cause it to run extremely hot (made a thread concerning this not too long ago). Was considering putting heatsinks/ramsinks/fans on the MCP355, but I'm just afraid that the GPM on my loop would be so high that it may burn out the MCP355 after a while. Therefore, I'm curious as to whether I should re-sell/trade my MCP355 and get an MCP350?

I'm currently running an XSPC X2O 750 pump/res combo, and I'd like something a little more powerful for future options. So would an MCP350 be plenty for a CPU block + gpu block + 2 radiators? I'm sure it would be, but I'd like to hear peoples opinions. Or should I just keep my XSPC X20 750 in my loop?

I have 2 rads and a cpu block right now on an X20 750 and I am adding a gpu block and probably a 140mm or 120mm rad. I was going to get the MCP355 or 655 but you bring up an interesting point. I was previously recommended an mcp 655 and I cant see it being too powerful to pump through 2 rads, a cpu block, and a gpu block. Maybe that would work for you having less head pressure than the 355?

I'd say go with the 655. It has less head, but has a faster flow which would be optimal for your system.

Wasn't asking about a 655. As stated in the OP, I have a dual bay res/top for DDC pumps, can't use a D5/655 with that.

You could always sell your bay res and get a Swiftech MCRES. Now to answer your question, the 350 will have more head pressure than the X20 750 so it should push the water through your loop better than the 750 for your setup. But like we said, I think a 655 is your best bet. Hopefully someone will show up with more information.

Bump, I am curious to see what others have to say about this.

The MCP350 will run cooler, uses less energy, and fits in a smaller package. The flow of the 350 with head pressure is better than the 655 within his DDC Bay RES . Look at Martin's pump reviews.

It's easy, get a single or a pair of 350's. Look for a pump maverick.
