EK Supreme + Eheim 1048 Pump = Problem?!

[strelly]

I been spending most of the day setting up my first watercooling build. It is a CPU only loop, with a modified polo heatercore, a eheim 1048 pump and a EK supreme waterblock; all with 1/2" tubing.

To cut a long story short, i spent about 2 hours trying rid the system of air untill the pump stopped making a din. No luck!

I have since played in the sink and have found that this waterblock alone is making the pump winge. The pump is fine on its own (good flow rate), but the flow rate drops heavily when attached to the block (and the pump makes a rattling noise).

I have tried everything i can think of, dissembling the block to check its clean, using the pump to push and pull water through it(not at the same time!!).

I know the EK supreme is a bit flow constraining, but surely this shouldnt happen?


Im out of ideas and this is really annoying me!

Any help would be greatly appreciated!

I had exactly the same problem!

The problem is that the supreme is basically too restrictive with the plate in place for lower powered pumps.

You can fix this like I did by taking the block apart removing the metal plate and cutting out the laser cut fins.

Put the modified plate back in again and....

The flow rate has now improved in my system dramatically! and as a flowrate is better so is the cooling performance.

The Eheim 1048 will 'rattle' with restrictive waterblocks. To cure this, you can take out the 'spindle' and use PTFE tape on it and put it back together.......no more rattles.
Drop me a note and i'll send a link on how to resolve this

Hey all, thanks for the replies,

I didnt indeed put PTFE tape on last night and it solved the problem!

Now everything is going well and my Q6600 is at ~23°!

Ill give a few days to settle then ill overclock the socks off it!

Thanks!
