What pump should I get for this loop?

post #1 of 17
Thread Starter 
So here is what I am going with on my first wc set up.

XSPC Dual DDC Dual 5.25" bay Reservoir
XSPC RS240 - CPU RAD
Primoflex Pro 3/8″ ID 5/8″ OD – Clear
Bitspower Premium G1/4" Black Sparkle High Flow 3/8" (5/8") Compression Fitting
EK-Supreme HF – Acetal
Phobya Xtreme 200mm - GPU RAD
Video card blocks - Undecided

I know little about pumps and how much force I need for a two loops. I was looking at Swiftech MCP 350 x 2 but they are quite pricey. I need pumps that fit the Dual DDC Dual 5.25" bay Reservoir due to the fact this build is going to be inside a 650D.

Any reccomendations are appreciated.

Well, you need a DDC pump, so the MCP350 and 355 are the obvious, if not only, choices. If you don't mind doing some re-wiring, there are some 350s available for $35 here.

Personally I would go 1 giant loop with a 355 or 655 you should get some nice temps. But if you want 2 separate loops your stills pending 70ish on a pump. Any reason you want to go 2 over 1?

To be honest this is my first time water cooling. Can I set it up with one loop? Dose it really matter?

One loop is fine - temperatures won't be much different. Using a dual loop setup would mostly just give some peace of mind.

For most PC uses one loop is actually better, as the full cooling ability is available to all components.

A single 355 or 35x (PWM version) will be fine for one loop. I would get the single version of that res, a 355 and put everything in one loop, it will be cheaper.

So would a setup like this work

Pump=RAD=CPU=GPU=RAD=Back to pump

Sorry my drawing never was my thing

One loop is easier to manage/maintain and performs very close to 2 loop setups. Also 2 less tubes in your case so it looks cleaner.

Pump=RAD=CPU=GPU=RAD=Back to pump is fine no issues there after an hr the temps are all equal in the loop anyway.

Im also new to watercooling so I might be wrong on this but if you have 2 radiators, wouldnt it be better to put one before the cpu like you have but put the 2nd one between the cpu and gpus? That way the water gets cooled again before it passes through the gpus. The way it looks on the drawing is that you are cooling it before you cool it. Again, im new so I may be wrong.

Makes the tubing kinda messy and lengthens the loop. And the water will still reach one temp no matter how you route the tubing. Just remember the only thing that matters is the res (if you have one or it's not part of the pump assembly) goes before pump.
