Pump suggestions and help

post #1 of 11
Thread Starter 
Hey guys, I am running a MCP655 with a EK top. Its pushing water through a 360 xflow rad->EK Supreme HF (plate 3) -> Bitspower NB/SB CHipset block -> EVGA GTX480 FTW HC -> EK spin res. As you can see I am running a lot of 45's and a 90 elbow. I know these create restriction but I am really big on clean looks. As you can see from the pic I am running two 45's on the 480 but do the bend from chipset block to the gpu block i am considering adding a 90 there and may exiting it as well just for good looks. Because of all this restriction I am wondering if adding another 655 with an EK dual top block would be worth it. Thanks for your input in advance.

EDIT: That hump from chipset to gpu is much more stressful than looks in the pic. Added another pic show more of the setup.

Yep, lots of restriction there. Might be better off with mcp35X with a good top instead of throwing more good money away on mcp655's. Maybe you can sell the 655 setup? The MCP655 isn't very good for high restriction loops.

I am considering that as well. I just want several suggestions and input before I make a decision.

I don't see your RES,but there is another option for you,get RP-452X2 and run 2X 655's,no need for tops;

My rig is practically one giant block and my 655 pushes water through it just fine. How many 90s do you have? Are x-flow rads terribly restrictive?

Depends on the budget and whether you want a single pump vs two pump in series. Personally for one single pump the Iwaki R30 is my choice for high restriction loop due to higher construction quality usually last 10-15 years. Here is the Iwaki review in case you interest in the performance.

If money is an issue another MCP655 or MCP35X pump would be a wiser choice, but I don't see how your pump is struggling with your current setup. MCP655 + aftermarket top should able to handle a few gpu block and radiators.

NO, x-flows are designed for less restriction.

That GPU block and Motherboard block are extremely restrictive, you are definitely outside the optimal bounds with the 655 pump.

I'd suggest an MCP35X, it would easily power your setup while being more compact, supporting threaded fittings out of the box and retaining that same noise profile of the 655 (maybe even quieter).

I heard they get quite hot though.
