Any Leak Stories?

post #1 of 5
Thread Starter 
Hi all.

Anyone here have any coolant leak stories they fancy sharing? Here's mine:

Few weeks ago, i decided to add my old Dtek Fuzion GPU (V1) to my CPU loop. The block had been gathering dust for over a year so i figured why not?

Installation went fine, leak testing was great. So i started using the system within a day.

about a week later when i awoke one morning, i started playing music and the audio was extremely quiet, even when the volume was on full.

I immediately suspected a power problem to the soundcard (Asus D2X) as it requires power directly from the PSU - perhaps the connector was loose or something. So i took the case side panel off to investigate...

Turns out the GPU block leaked, and left a nice big puddle all over the soundcard that was just about to migrate down to the PCI-E connector on the motherboard. I often leave the system on overnight so as i slept it must've developed the leak.

I was extremely lucky to have caught it when i did. Even moreso considering after clearing it all up, and fixing the leak, the soundcard worked (And still works) perfectly.

And all i use is distilled water with automotive antifreeze!

Nothing that interesting from me... My only leak was a trickle from my GPU block that I installed earlier this week. I screwed in the barbs so that there was just a bit of pressure on the o-rings, not enough to squeeze them tightly, as I didn't want to squash them. Well, during leak testing it started seeping water, so I tightened it up to the point of squashing the o-ring (at least what it looked like), and it hasn't leaked since. That was 3 days ago I guess, and I ran for 2 days with the side of the case open and paper towels under that connection to see any water spots. No spots, so now the case is closed up and back under running conditions.

I did as much as I could to prevent leaks by using 7/16" tubing on 1/2" barbs and using screw-drive hose clamps on all connections. I'm more concerned about my fittings leaking now than I am about the tubing

The tightness of fittings with rubber seals is always one i seem to get wrong.

I think thats why my GPU block leaked. It consists of several layers, the top being a pexiglass layer with a very thin rubber ring to seal it. I assume i must've overtightened it years back when i used it. Because thats' what leaked.




I've also noticed hairline cracks in the glass on the corners, so overtightening is probably the cause.

But so far, i've not experienced another leak. Fingers crossed it won't do so once the tower goes back into its final resting place within my glass desk (right now it's been on the floor during leaktests)

I recently switched from feser coolant to distilled water and biocide. I had to undo everything because i also got new tubing and i guess when i was pulling off some tubing i unscrewed the barb a little. Well i got water all down the back of the case and into the psu. I didnt know it was leaking until the machine totally shut off. Then i smelt a burnt smell. Then the stomach dropped to the floor. After i let it dry off for about an hour or two i hit the power button and nothing. I looked at the blue power led on the mobo and it was flickering. I let it dry over night and it came back on thank god. However, that burnt smell was my sound card being cooked. Apparently i had plugged in a 3.5mm jack that was sitting in a puddle. Didnt see the puddle til later. I ordered a new sound card for 26 shipped with optical output and called it a day. However, this was a learning experience, i learned that sound cards destroy on board sound any day of the week. Dolby head phone is awesome and so is 7.1 virtual surround

I stripped a loop down and dismantled and cleaned the block and left it to one side while waiting for a new case to be delivered. A couple of weeks later I reassembled the block and rebuilt the loop. I started filling it and was thinking that it seems to be needing a fair bit more water than last time when I noticed the water flooding out of the block... I'd forgotten to put the o ring back in

I stripped it and washed the mobo with isopropyl alcohol, left it for a week and it's been running fine ever since.
