Help choosing the right pump

post #1 of 15
Thread Starter 
Hey guys. I'm wondering if I might be hitting the limits of my XSPC Rasa kit's bay res/pump. I currently have the XSPC Rasa CPU block, 2 EK HF Supreme GPU blocks in parallel with a swiftech universal gpu SLi Bridge, and a RX360 rad. Will be adding another RX240 rad and compression fitting in the near future. So I'm trying to find out if I really need another pump or not. I've been looking at the MCP655 and MCP355's and really its all a lot to take in for a WC newbie. Also I know bmaverick is selling some MCP350 equiv pumps and have been looking at them as well. Any help would be greatly appreciated.

Not sure, but the MCP35X pumps are pretty robust.

I was going to get 2 of bmavericks pumps and use a aftermarket top like this xspc one. Would that be enough for anything I through at it?

you probably get away with using the mcp35x pump

Any of those options will be fine flow rate wise. A single D5 (MCP655 / PMP-450) or DDC 3.1 (MCP350) will get you up to ~1GPM which is all you need. A DDC3.2 (MCP355 / PMP-400) or a MCP35x will boost you well over that and give you room to spare.

Be aware that whilst the pumps bmaveric is selling are a good option they are also quite loud. I found them to have a particularly high pitched sound which was quite irritating to me. If you don't care about noise then they are great, if you do then it is possible to do a PCB Mod for $10 plus ~2 hours of work with a soldering iron. This still makes them a good deal and I am very glad I went that route with my pump.

So you are saying just one MCP355 or MCP35X would be enough for my loop?

Yea, the 355 is the most youll need, I just said 35X cause the 350/355 is about the same pump, but i didnt mean the new 35X lol.

350 is the 10W version
355 is the 18W version
35x is the PWM version of the 355 with a better stock top

Actually the 350 and 355 are identical except for a solder bridge on the PCB. You can easily turn one into the other if you really want to.

Any of them will get you at least ~1GPM even with the stock tops, the 355 and 35x will get you more.
