1 pump...or 2?

post #1 of 12
Thread Starter 


That big black box is this. Which is what the rads will be housed in. This is a test bench build

Thoughts?

My main question is, do you think two MCP655 pumps would be necessary for this, or can I get away with one? Alternatively, would I see much better temps if I had two pumps connected in serial like that?

Items in loop:

CPU - XSPC Raystorm
4x GPUs - In serial just connected the "old fashion way" I prefer the look compared to things like this. If things like that are much better for loop flow rate I can be sold on them.
3x 3x120mm EX360 rads
FrozenQ 400mL Double Helix Res

Eventually a pair of ram blocks and a motherboard block will be added... just not right away.

For fittings I'll be going with bitspower. 8 90 degree angled compression fittings and 4 regular compression fittings.

Do the 355 or 35x really run hotter? I have read that they do and die faster..... Surprising that they are better since it is a smaller pump...

The mcp355 performs better because of the head pressure. The mcp655 comes close to the mcp355 cause of the gph.
I have two mcp35x they do run hot just need some air flow to them. They are still chuggin along witph no problems. The mcp355 does not get that hot compared to the 35x
