loud pump

buy prime i mean make sure its full of fluid so there is no air and also it has head pressure as in enough fluid pressure at inlet to give continuos flow.

tbh it sounds like its full from what you just said but there may well be pockets of air restricting flow else where.

cant hear a murmor from mine and its on my desk in a separate control unit to my pc

and its on the rubber or foam pad and locked in place by the rummber mounts that come with it.



even tho you dont see bubbles at the pump inlet or out let there may well not be full "prime" or flow thru the system if theres is an air lock somewhere else that you cant see.

worth doing the pick it up or move it all about bit to see if you get any air to bleed out. imo

and also because your header looks topped up doesnt mean to say theres no air else where untill you make sure any air has worked its way out as in the statement above

it still could be a damaged impellor in the pump mind you or a lose one. rattling around in there
 
your pump outlet is the one going vertically up right ???

reason im askin is cause if so i would connect that to the top inlet of the unit it goes to i geass thats your header tank up there ?

so that should fill from the top and drain from the bottom

looks like you are filling it from the bottom and draining from the top if you see what i mean ?




just looked at your edit also defo shouldnt be fluid from there seems weird that tbh

if you can try it swap the inlet and outlet sides at your res for the reason above

if that doesnt help and the pump is defo leaking send it back

yes, the outlet of the pump is the vertical. Yeh it goes to a 150 basic EK res. I'll see how the PSU is doing (going to leave it with radiator and towel overnight to see if it comes back to life) and then report back.

I mean, if people are saying that they "don't hear a murmur" from their units then mine is far from that so something is up. Will report back soon
 
try putting the outlet of the pump to the top conection on the res mate just in case


if not cant see anything wrong with the layout must be a dicky pump imo
 
You are going to hate this, but your res should be feeding the pump, not the other way around. Basically you can use your components in any order, providing that the res is connected directly to the pump INput. Literally just swap the in and out hoses over. You could also rotate the block 180 degrees, purely for aesthetics and a minimally shorter amount of hose in the loop.
 
ah yes you're right. Th res should be before the pump! Even so, would this mistake really cause the pump to be so loud.... i'll dismantle and flush the system with de-ionised water. Also, ill try just the pump by itself with some shorts of tubing and a bucket of the water to see if its still noisy with no components in a loop (thta should isolate whether the pump is at fault right?).

Then if the pump is ok i'll redo the loop but with the res before the pump.
 
I have the EK 4.0 pump, its my second one as the first one was faulty as it was making one hell of a noise. I got a replacement which is quieter but still what i'd call loud as its the loudest thing in my case, even with the EK mounting kit with foam dampening.

I really think the EK pumps are not as quiet as they claim to be, I'm swapping out to a Laing DDC-1+ Ultra Pump with a EK Res Top as im not happy with the noise.

This is just what i've experieced with EK pumps, but ive heard others have had noise problems aswell. Although, some people have said they are whisper quiet, but it could also depend how good your hearing is ;)
 
The Ek2.2 should be quite (even to me) if it's not - it's either damaged or the vibration hasn't been isolated.
The Ek4.0 is noisy imho, but if you live on a busy road and have 3 or more 1200+ rmp fans you shouldn't hear it.

My own testing of Pumps ranking in order of quiteness (with GPM on a multiblock 120.3 loop)
All pumps are fully issolated and no other fan noise is present.

Green zone for 'quite' watercooling
Orange zone will be masked by fan noise (3x GT's at low rmp + psu fan + case fan)

ive got the 2.2 and it doesnt make a noise at all so it seems weird cant be that much variation in them surely if so that doesnt show very good quality control ive tried it with the cover off my control housing also and cant hear it.

tbh i think his rad is high enough and will feed the pump fine and his res can be that way round if he swaps the inlets and outlets of the res over

it sound more and more like a dicky pump tho especially now other people saying they have had same issues and with the water leak bit aswell

its only a few minutes to swap it round so worth trying
 
yeh i swapped it all around and drained it and used just pure distilled water ( as i ran out of dye with the kit) and the pump was still being annoyingly loud. Tightened the screw that was leaking, it did twist maybe another 16th of a turn so there was play in it. still noisy though even if the leak had stopped (didnt run it for a long time so it may still leak a bit). Had the res in front of the pump this time- no difference. In the previous setup the rad was high enough and kind of acted as a res as you can top it up with coolant at the dummy holes.

Contacted OCUK and theyre happy to refund if i send it back- i'll go for a different cooling solution, has kind of put me off thew ater cooling though with this experience- don't know whether to try a different water system with different pump OR just get a NH-d14 and leave it at that? Got vengeance lp (low profile) ram so the unit would clear it...

I would definitely recommend a Liang DDC (most likely with a aftermarket top) if you get a different pump, just replaced my EK 4.0 pump with one today and the difference in sound is insane.
 
when i took the loop apart it sounded like the impeller was schlocking around a bit...may have been the issue...
