I was changing my DVD writer today as the old one has been playing up recently.  When I pulled it out of the case, it had a pool of green liquid on top of it, the same colour as my water cooling coolant.  I pulled the WC tank out, which sits above the DVD and Ive noticed that the three spouts on the tank have all got cracks in them.



Its been sitting there without a problem for over a year.  Although the spouts are screw in, I havent over tightened them as they were pre installed when I bought the kit.  The kit is the Corsair Cool.

Has anyone else seen this happen?

In a pressurised system there is often strain on those sort of places when it gets regularly heated and then cooled off. Its caused by water expansion and contraction, usually it develops over a very long time though.

bit of epoxy in the crack will be fine.

if its a thermoplas, the get some polycement filler on it

good as new
