best way to find leaks?

post #1 of 12
Thread Starter 
What do you think the best way to find leaks in the radiator are?

I'm having trouble finding some and worry how deep they are.

I would lay the rad down on some paper towels, run water through it and see were the wet spot forms.

Are you absolutely positive that your rad is leaking?

I plug one end of the rad. Hook a hose to the other. Fill sink with water. Submerge radiator. Blow in hose. Watch for bubbles. Rinse/repeat.

I am certain because I've been finding drops of water on my GPU

What a terrible way to find out huh.

Flashlight, you should see watermarks coming from the fitting or block. Paper towel too, should be right below the leak.

I suggest you jumper your psu without turning your pc on and do a leak test.

+1

Also are you sure its not the CPU block? Like maybe the fittings/tubing? I'd wrap some paper towels around them for a day or two and make sure its not a slow leak.

Is it at all possible that a fan retention screw has pierced a tube in the radiator? If it is not a fitting or where one of the end tanks join the core all you have left are the tubes, now how can a tube get pierced,from a screw that was too long.

Are you using any swivel type fittings? these are very prone to leaking if pressure is pushing on them in any direction.In two of my loops the only place a leak can happen inside the case is the cpu block or the hoses to it,everything else is outside the case.I realise many people do not like their cooling gear to be external, I am more for function than looks.

This is one of the few things where UV coolant actually helps.
With a UV light you can see the places where it has leaked
