New Ek dcp 4.0 pump very noisy

theoni · Nov 19, 2013

Hi all,

This is my first time I'm using water cooling.
I'm building a new system with this:
- asus maximus v formula
- i7 3770k (not overclocked yet

)
- 2 x gigabyte gtx 760 4g (not water cooled)
- seasonic x-1250 gold
- ocz vertex 3.20 140g (OS)
- ocz revodrive 3 120g (foto editing)
- 2 x WD black 1T (data)
- ek-kit h3o 360 hfx
- additinal 360 xt rad (maybe a bad decision)
- 3 corsair SP120 HighPerf for lower rad (push)
- 3 corsair SP120 HighPert for upper rad (push)
- 3 corsair SP120 Quiet for upper rad (pull)
- additional 11 case fans
- corsair obsidian 900d

Th loop: pump - res bottom - mb - res upper - cpu - reservoir - pump

The pump is mounted at the buttom of the case using ek pump mounting plate.
The plate is on a spunge for the vibration.

Even when I keep the pump with my hand up the air there is a loud buzzing from the pump.

Is my loop ok?
I do not think there are bubbles. I've shaked everything.

Measured the decibels with an iphone app shows around 60db.

Any ideeas what it is wrong?

Thanks,
Theo

The pump must always go after the res.
It sounds like you are starving the pump. If that is the case your pump will be dead very soon.

Thanks for the quick reply.

So it should be like this?

pump -> mb -> upper rad -> cpu -> reservoir -> lower rad -> pump

Soulcatcher668 · Nov 19, 2013

The only thing that matters is the Res is before and above the pump.

You water temps will only differ 1-2 degrees anywhere in your loop so the rest of the loop is what ever looks good.

Other thing is that these pumps have sometimes weird noise issues. It's like it can be almost silent for 2-3 weeks and then from time to time you hear buzzing. Or new pump is making that noise and after couple of days all is fine. I had about the same with 3 EK pumps.
Btw. nice looking rig you have there :thup:

theoni · Nov 19, 2013

I was not clear in the first post, sorry about that.

My reservoir is before the pump:

PUMP -> lower radiator -> mainboard > upper radiator -> cpu -> RES-> PUMP

almost like here: http://www.overclockers.com/forums/showthread.php?t=724576 but without the gpu cooling.

I've noticed some condensation in the reservoir. Can this cause any problems?

Should I drain and fill the loop again? would it help the noise?

theoni · Nov 19, 2013

Thanks for the reply Woomak.

I hope it will stop buzzing because is driving me crasy

It's running for 4 days now.

I was thinking of buying on of this: http://www.frozencpu.com/products/1...R-SPD10_12V_Pump_or_Fan_Speed_Controller.html

The strange thing is that the pump resonates somehow with the case.
If I lift it up a little bit with my hand it stops resonating but it is still noisy.

Of course, the noise was worse when the pump was mounted with bolts on the bottom of the case.

Could I put it in some gel case without overheating it?

Any other ideas of what could be wrong or how can I reduce the noise?

Soulcatcher668 · Nov 19, 2013

The res is full?

You will have some condensation in the res if there is space in it.

I am not familiar with that pump, so I do not know how loud it is supposed to be.

Edit*

You are getting 60 dB? EK's site states a maximum of 25 dB for that pump. I would check your vibration isolation again and then call EK support it if it still that loud.

I'm building a new system with this:

I had a 2.2 pump. Got myself a Laing DDC-1T instead, much happier. In your case I would have gone with Laing D5. I changed cos the EK 2.2 was ridiculously noisy.

I do not agree what so ever.

The pump will always generate heat, it may be small but it done.

The Res should at all times contain water, therefore all logics would suggest that the res should go before the pump.

At the end of the day, the order does not matter more than 1-3degrees, but i see no reason why the pump must go after the rad.

I have 2 systems with watercooling, both run Res - pump - Rad - block - res.

If a pump made vacume, then i would agree it would be the logical way to go, but since all the pump does is move liquid, then I simply cannot agree.

Grr..... typo. I meant res. Good catch Pierre.

theoni · Nov 19, 2013

Yes, I know it should be 25db.

When the pump was mounted on the bottom of the case with bolts I had around 90db. Without bolts it's around 50db.

The res is not full at the moment. The water is just above the EK vortex thing.
I'll fill it again with distilled water and see what happens.

Another thing is that when I've put the liquid in the loop I was with a friend of mine and none of us noticed any annoying noise. Who knows, maybe we were just enthusiastic about the water cooling stuff

@woomak: forgot to say thanks for the appreciation

added specs:
4 x 8G = 32G Kingstone HyperX Beast 2400MHz DDR3 PC3-19200 Non-ECC CL11 DIMM XMP
Dell U3011 (manly for lightroom/photoshop)

Still have a lot of issues, fan pwm connection to the MB (angry about fake 4-pins on the MB), lighting (waiting for fronzencpu delivery ~2 weeks

), pissed I cannot see deep color for 10-bit output, I guess I need quadro after all

I promise I will put a final picture when it's ready

Ahh ok, sorry if i came off as a disagreeing jerk

You should click on "user cp" in the top bar, and then on the left side menu, you will find "edit signature". Add your system specs like others do, much easier for future :thup:

will do

thanks Pierre3400

The same happened with mine: after 1 week running 24/7, the pump started making noise, but it stopped after a few hours and never came back.

theoni · Nov 19, 2013

Ok. I've made up my mind.... if it does not stop making noise by the end of the week I'll order a new one.

Any recommendation of a silent pump good/compatible with my loop?

how about this: http://www.frozencpu.com/products/1..._Perfectly_Tapped.html?id=ZkHM4XdR&mv_pc=2257

In your case since you are moving sothe water in such a big loop, the Laing D5 would be a great choice.

http://www.frozencpu.com/cat/l3/g30...PC_Water_Cooling_Pumps-D5_Variants-Page1.html

Which ever one suits you, get one with a top that will suit you and the loop layout.

I run the D5 in my loop, but i have the Pump/res solution from EK, think its called EK D5-Xres or something.

Thanks Pierre3400 for the answer.

I'm a little bit confuzed. :shock:

Should I get this: http://www.frozencpu.com/products/1...d.html?tl=g30c107s1802&id=ZkHM4XdR&mv_pc=3955

or

http://www.frozencpu.com/products/1...d.html?tl=g30c107s1802&id=ZkHM4XdR&mv_pc=3966
and
http://www.frozencpu.com/products/1...d.html?tl=g30c107s1802&id=ZkHM4XdR&mv_pc=3966 (do I need this? )
and
http://www.frozencpu.com/products/9...n_Molex_Connector.html?id=ZkHM4XdR&mv_pc=5573
and
O-ring (what is this? )

Another thing is that the fist one is PWM. Would it work conected to a PWM socket but not CPU one?
Right now if I connect 1 pwm fan to this socket it works fine, I can control it and the MB sees it but if I connect 3 daisy chained fans using akasa 3-way splitter it does not work.

sorry for so many questions

Link 1 - Its a fancy dressed up version! Unless you want to pay for it, no reason to get it.

Link 2&3 same pumpe.

Link 4, not a single reason, unless you want control over your pump.

I run my D5 at setting between 3 and 4, works fine, and silent.

Since im sure you already have fittings, why not get one of these?

They give you a few more options on inlet and outlet.
