Pump choice for short loop

Bart_Hunt · 13 Oct 2013 at 07:35

Hello guys

I have a problem with choosing the right pump for my loop.
I am building a new system which is going to have:
i5-4670k
Radeon R9 280x/290x

Its a mini itx case so radiator will be located outside, I wanted to use a 240 or 360, probably Black Ice Gtx or sr1, as I am planing some serious oc'ing.
And now comes the pump problem.
I would like a quiet one, so looked at EK DCP 2.2 pump, but is it strong enough for overclocked Haswell and overclocked high end GPU?
So I looked at Laing DDC 10W, but it looks like I would have to use kink coils on it. I have seen what a faulty one can do to your system, so I am not really interested in that.
Then comes DCP 4.0, but apparently there is a problem with noise.
I may have to buy a D5, which is strong and can be tuned down to make it run quiet, but my budget isn't big, anyway do I need a pump that strong in a mini itx system?
X20 750 isn't an option either as this case doesn't have any drive bays, besides I would like to have a choice of different res.
So I am back to square one.
I will have to make decision soon and would prefer to avoid making a bad purchase.

I appreciate any advice you can give me.

Cheers
BH

Thanks, that explained a lot

Other than pump, loop will have:
Xspc photon 170 tube res
xspc rs360 rad or Black ice360 gtx/sr1
3x Gentle typhoon 120mm 1850rpm
ek-vga supremacy nickel (for 280x) or 290x full cover waterblock
ek supremacy cpu block
10/16 hose

Thats pretty much it. I dont plan ram cooling, the case will have pretty good airflow (1x120mm AF fan front intake , 1x 120mm AF fan rear exhaust), at least for mini itx case.
Check the link in my sig, pics will tell you much more about the case than I can in words

I can only add there is loads and loads of vibration and sound proofing in that case (all walls have at least 5mm).
I'll make a diagram of watercooling I had in mind and post it there tomorrow.

Cheers

Andybird, considering your sig, I am not sure I should take seriously anything you say

I looked at DDC and I have to say it was one of options, but it looks like they have a built in plastic barbs. That's a big NO for me (I am going for monsoon compression fittings).

To be honest, my current project may require making a separate loop for GPU and CPU.
I will probably use DCP 2.2 x 2 + 2 x 240mm rad (1 for each pump), that should give me enough pressure, right?

Not if you are planing to have coolants of 2 different colors.
Its this kind of thing that works good and looks even better

This is a first custom case I am building, but not last - next year will be packed in my projects here on forums, so I need to accumulate knowledge until then.
