Very restrictive loop vs mcp 355 - can it make it?

[c22]

Hello,

I'm rebuilding my loop in lian li v351 - as you know very little case, but still I got some liquidcooling stuff in it.

New loop will be VERY restrictive I guess and I don't know if my pump can handle it..

Here it is:

XSPC bay reservoir -> pump -> ek supreme hf -> mips r3gene mosfet -> mips r3gene nb -> mips r3gene sb -> TC pa 120.3 -> TC pa 120.3 -> XSPC reservoir and so on.

I I will be using at least four 45 degrees fittings to place 2 compression 10/16 enzotech fittings at nb & sb block (those are quite small and without 45 degree fitting they won't fit).

Should I think about new pump? I'm using my mcp 355 with ek x-top v2, so it's a little better than stock pump, but I don't think it makes any difference...

Supreme HF are actually very high flow, as are thermochill's. MIPS will be your restriction, but a DDC with it's great head pressure will have no problems. You'll be more than fine.

OK, if you say so. What if I wanted to add EK FC-GTX560 block in the middle of the loop? Would my mcp355 still be sufficent?

[zeropluszero]

maybe if you were going to add 4 video cards. and a swiftech XT CPU block...

you'll be FINE.

Yep. You might even get away with a MCP350 in that loop. I'm on a FuZion + 2 rads and a Koolance full-cover getting over 1GPM with a little itty-bitty EK-DCP 2.2 pump- MCP350 was too fast and noisy.

I had a single MCP355 churning through an XT, 4 rads and two FC GPU blocks (295 hydrocoppers which were super restrictive) and flow wasn't great, but it was not so low as to affect my temps as to affect my overclock. Only problem I had was pushing out air bubbles from all the rads.

a Fuzion is very low restriction though.

this sounds more like a high restriction loop.

this sounds more like a high restriction loop.

It was. I also had a number of 90 degree BP barbs, as well as 2 pairs of Koolance VL4 QDCs and a dead pump for the 1 MCP355 to pump through. It was an insanely low-flow loop and actually surprised me by how resilient it was to that. The GPU temps were higher quite significantly (around 5 degrees idle, 8 or so load) than before the second pump died, but the CPU (XT) only showed a 1-2 degree increase in idle and no increase in load temps, oddly enough. Very low flow resilient.

Overall the loop went:

MCP355 w/ XSPC Res --> dead MCP355 w/ XSPC V3 --> Rad 1 --> Rad 2 --> 90 degree --> VL4 QDC Pair 1 --> FC GPU 1 --> 90 degree --> 90 degree --> FC GPU 2 --> VL4 QDC Par 2 --> XT --> 90 degree --> Rad 3 --> 90 degree --> Rad 4

OK, so I can see there's nothing to worry about any my mcp will handle this without any problem :) Thank you guys. I will be posting soon (2 weeks) my worklog here, hope it will be good.

a Fuzion is very low restriction though.Of course it is, but I had an MP-05 SP LE in there before that was higher restriction than a Storm paired with a HW Labs GTS360 rad, EK FC8800 and Swiftech MCW60. Still TONS of flow with an MCP350. ;)
