Help with small leak

spook050 · 12 Mar 2016 at 12:52

I have had a nightmare 24 hours trying to get my pc up and running again after a pump replacement. Ill cut the story short and say I have had to fill and drain 3 times so far and I am loosing my mind and patience! haha

The latest is that I have now filled the loop with crystal clean distilled water and have been watching it for the last hour. Everything seemed to be going well until I seen a small drip forming on the CPU block. IT appears to be coming from the bottom of the EK "Sticker"(Atleast I thought it was just a sticker). I have used paper towels and confirmed that the top of the sticker is dry, so its not coming from the fitting above it.

Can anyone tell me what that sticker actually is? And any suggestions for quick and dirty fixes as I really do not want to take this thing apart again. Im thinking some sort of plumbers tape or super glue? It is a really small and slow drip.

Thanks for reading if you made it this far!

You guys are right, I left it for an hour and went back to it and it was clearly coming from the fitting and running down the right side of the block. There are a few small visible cracks around the fitting hole where I must have tightened it too tight trying to stop it leaking. Not sure if that's the cause or if it is the o ring you mentioned.

I'll maybe try taking it apart tonight and upload a few pics of the o ring if you'd think that's the best course of action!

Thanks for helping guys, I was getting frustrated with it earlier!

Thanks guys for giving me some options. I am going to drain the top half of the loop again here and take the pipe off so I can take a better look at the cracks. I will upload a pic if I can get a good one. There is a homebase near me that sells that sealant and is open for the next 3 hours so I will seriously consider that if it looks possible. If not the top that pastymuncher found seems like a steal at £7

Ok guys, I think we have found the culprit, it definitely looks like a crack could be causing it.

Below are some of the pics I took of the cracks. They are all pretty small and I can't feel them when running my nail over it apart from the one slightly bigger crack at exactly 3 occlock or 90 degrees. I can feel it with my nail and it seems to be the biggest one - its also at the correct side of the leak. What do you guys think? If I go for the top will I be able to replace it without fully draining the loop, at the minute the top half is either drained or shut-off, so I can work at the cpu pretty independently.

Again cheers for the help guys, this has been invaluable...

Ok quick update guys. I bit the bullet and decided to tried rubbing sealant over it. It's been running the past 60 minutes without a drip. Still might order that top, as I think ill be forever nervous about it if I don't .. I will see how this goes and have a think about it. If it runs for the next 4 hours I might leave it on over night.

I will do a little research to see if that supremacy top will fit my evo top as its dirt cheap. I think you are right, I could probably change it without draining the full loop, I can just get the cpu out of the loop.

Looks like the silicon is holding up. Its been running for the last 14 hours with no drips. I think I will power it up properly soon. I didn't put any silicon on the threads, just on the outside and a small amount on the small groove before the thread starts. I also used a little pfte tape on the thread.

Ordered the supremacy evo upgrade kit. Hate paying £10 delivery for a £7 item but its a lot cheaper than a new component if it leaks. Silicon fix should hold me over for a while until I get time to fit it.

Cheers again guys.
