Just got my first watercooling loop set up. The EK H30 HFX 240 kit.

It has the EK 4.0 pump....I thought watercooling was supposed to be quiet...the pump makes a load of noise?! All air bled out and everything. Are you supposed to decrease the voltage or something? Temps are worse than a push-pull H80 i had too.
 
Another person with this.
Is it a vibrating sound or knocking?

If vibrating, just hook it up to a decent fan controller. My FC6 says that going full whack its pumping at 2krpm, but turn it down to 1.2k and its silent and still pumping well.
 
My 2.2 pump the baby version of yours makes a hell of a noise aswel. Infact since watercooling my gpu thats the loudest thing in my system now. Surrounding the pump in thick sponge helps dampen out the sound though.

Ill get a vid/pic up soon. Mid exams at uni at the moment. The pump is by far the loudest thing in my loop now...everything else virtually silent.

I just thought watercooling was supposed to be silent. The H80 i had was faulty and i sent it back but when it was working properly (upon occasion) it was silent pretty much. Just a bit of a let down to spend over £200 and have a noisier pc.

Uses the ASUS fan xpert sotware on my pc to drag the pump speed down to 50%...still audible but not as much as before. Its not case vibration or whatever..the noise is the pump itself
 
It's the vibration that's causing it, you can take these pumps down to 5v & still have decent flow (I have ek supreme hf full nickel, ek gtx 480 & a thermochill 360)
 
to take it down to 5v (also is that quiet at that point?) would i use control via a motherboard fan header OR power the pump from a molex with a fan controler / voltage reducer. I tried a voltage reducer fan cable that came with my noctua nf-f12s and the flow wasnt great...cpu heated to 60 degrees at idle so it obviosulty dropped it too much.
 
weird that people are getting this my ek dcp2 is quite as hell here mounted in my control unit on the standard rubber mounts and pad

 
that kit comes with an isolation kit, use it and enjoy the quietness.

oh and if your temps are poor either the block needs reseating or there is air in there somewhere.

i have used the foam and rubber mounts etc...still noisy. Ill post a vid up late tonight (revising for exams at university campus at the moment). even if i were to hold the pump with my hands up in the air then its still noisy. will get some info up on the forum later

air or residue in it then, I am leaning towards air purely because of the poor performance. What sort of noise is it?

ill have to do a vid as i cant explain...there is no air flowing in the tubes...fully bled out so i dont see how thered be any in the pump (which is the lowest point of the loop). Residue? well the kit is brand new- i dont know how gunk would have gotten in there :s

Oh you'd be surprised!
 
if you are using the res look for bits/discolouration, EK reckon all their kit is pre flushed and good to go out of the box, but I dont take anyones word for it. I still reckon air, but could be a dicky pump I suppose.
 
if you mount the pump on the deadning rubber and the two strips provided its not that clear in my pic as long as the pump body is not rubbing anything in the case it should be near silent

either it is cavitating as in not got full prime even if its at the bottom of the loop mine is near the top and as long as u prime it correctly it shouldnt suck air or cavitate.

or there is gunk as suggested can you easily check for residu or blockage ?

a good move about to be 10000% sure there are no air blocks etc

but it shoukld be near silent

could be a broken or loose impellor but doubt it
 
may have just spilt coolant on my psu while doing a top up to be sure of no air....so going to leave it to dry to see if its functional. It turned off but i dont know if thatll be a safety switch off or its just bust. ...ah crud. video may have to wait
 
also what exactly do you mean by "prime" :s the inlet and outlet of the pump has a bubble-less stream so i dont think there will be air in there?

best i can do seeing as PSU got splashed with me being an idiot. So no video of noise. I know the res-to-CPU block tube is long but I just put it together to see if it'd all work. Will redo it "nicely" after i've solved the pump problem. With reference to the pump. one of the 4 screws on the body had some remnat coolant and a small bit in bottom of pc case...it wasnt coming from the tube fittings but from the screw on the body of the pump. I tightened it a bit but cannot test until PSU is dry. Even then, the PSU may be a write offa dn i'll have to order a new one. Maybe this screw was the source of the pump noise?

this is a pic of the pump indicating where leak was from. Anti-vibration plates removed. Temps were i5 2500k 22 degrees idle...load untested
