Ek-dcp 4.0

post #1 of 12
Thread Starter 
Hey,

I purchased a EK Kit and the Pump that came with it: EK-DCP 4.0 i think is loud and website says "Extremely reliable and ultra-quiet" - Is mine broken?

Also i'm sure it's not powerful enough, when i touch the tube coming out of the pump you can feel the water gushing inside, but once it goes into the CPU and back out if i touch the tube or squeeze it a little only feels like 20% of the water is passing through

Set-up: Res > Pump > Rad > CPU > Res

Might just be me because i'm new to Water Cooling just paranoid that i have done it right.

depending on size of tubing you usualy cant feel it very much once it starts to go thru some of your blocks you can feel the water inside but not the flow. Like on my loop if i squeeze a piece of tubing i can feel the water pressure trying to push it back to full size.

It sounds like a bit of air inside the pump.
Have you let the system bleed the air out completely?

When you touch the tube near the pump, you're feeling the vibrations of the pump being transferred through the tube.

These pumps need to be mounted on some kind of mechanical isolator (like a bit of foam) in order to stop vibrations from making a bunch of noise. That's more likely than a broken pump. How is yours mounted?

Have you let it run, while shaking your case in all directions so that the air gets out of your system and your pump?

Nope, do i need to leave a port open on the res for it to come out?

No, no need to keep it open.
But you will want to run the pump on its own and tilt the case to different sides in order to take the air bubbles out of the pump.
That should remove that noise.

Noise in pumps is down to 2 causes, mechanical vibrations from the pump working, and air trapped in it.
You need to keep bleeding the air out. Top the res off, then make sure it's water tight, then tilt and shake (gently) the machine back and forth at various angles to encourage air to flow into the res and fill the loop entirely with water. Keep topping up the res and doing more tilting until it stops being noisy.

That pad below the pump, is it compressed?

By the way, a quick way to tell what's going on with the pump would be to remove it from its mounts and pick it up, it should quiet up a lot if the noise is due to vibrations.

Yeah it's compressed the big sponge that is supposed to go under it i didn't want to stick it to my case. In case i change the layout or something.

Any ways to avoid this?
