Thoughts and Experience with EK Supremacy CPU waterblock

post #1 of 6
Thread Starter 
Hi guys! I want to share my experience with an EK waterblock that i bought 3 months back when i was building my water cooling loop.

So i bought an EK supremacy plexi waterblock and while i was building my loop i decided to change the jet plate on the block.
After taking the block apart, i had a little trouble with putting it back together because the O-ring would slip out constantly.
But after struggling a bit i managed to put it back together and finish my loop with a feeling of "its gonna leak" at the back of my mind.

While doing my leak testing, true enough it leaked.
It was leaking slowly in between the gaps of the plexi and the hold down plate and the nickel plate.
I did not take pictures then, so i just grab some pics of the net.

So i took apart the CPU block from the loop and tried to figure out what is causing the leak.
I took apart the block and put it back countless times yet is was still leaking even though the O-ring were in place properly.

After seating down trying to fix the stupid leak for 2-3 hours to no avail , thoughts of "i shouldnt have changed to jet plates!", "EK is crap!" is all i had in my mind.
Staring at the block helplessly for a long while i realize it had all to do with EK's design of the block and why i was having trouble with the O-rings in the first place.
I Knew it had to be over tightening which was causing the leak, with this in mind i tried loosening the screws and setting up the loop again.
But it still leaked! and i didnt even use any strength tightening it!

So this time i hook up the only pump and reservoir to the block and ran it. While it was running and leaking slowly, i slowly loosen the 4 screws a quarter turns at a time. Each time i did that the leak got slower and slower and finally it stopped leaking. God you guys should have seen my face... i felt like i just solve an equation for time travel...

Why i suddenly knew it was over tightening was because after staring at the block for a long time i realize that EK's design for the O-ring placement was pretty stupid. I may not be a water cooling expert but i do know and O-ring works.
Ok so the problem here is that any normal water cooling seal consist of 2 contact points with an O-ring in between to prevent water from leaking, a normal tighten with your hands would be enough to form a seal.

BUT for some odd reason EK decides to put a 3 point contact for their waterblock.

For those who are not familiar with the EK supremacy waterblock.
here is a pic.




The O-ring here needs to contact all 3 parts, the plexi, the hold down plate and the nickel plate properly to form a perfect seal.
What happen in my case was that the plexi was tighten up against the nickelplate making the O-ring useless.
i had to loosen the screws so much that there was a small movement with the hold down plate.

I tried to search in google if anyone had a similar problem but nothing came up.
To those that who have an EK Supremacy CPU waterblock, i hope this helps you if you are trying to open yours up to.
Feel free to share your experiences here too, Cheers!

I have taken my Supremacy apart several times to clean and inspect including the first time to install the 1155 jet plate.

I have never had any trouble getting it back together and never had any leaking. I always tighten everything up so it is snug, but not forced, with an Allen key because that was what it was like when I bought it.

I had a feeling that it was only my block which had trouble since i didnt find anyone else with a leaking EK supremacy.
Maybe i was just unlucky but i managed to fix it so everything is good now.

You fit the o-ring in the octagon groove on the base right?

Yep. the thing is the groove is form by placing the hold down plate onto the plexi. without the hold down plate, there is no groove to speak off and there is nothing to hold the O-ring together.

Ok here is a drawing i made to make it easier to understand why i think the design of the block is flawed.

On the left is a normal O-ring contact and the right is the contact for the EK Supremacy.



Having another part to rely on for a seal is just asking for trouble, it just increases the chance for failure.
