FreakinCold's Waterblock Leakage
 

If you order a waterblock from www.freakincold.com be sure to test it IMMEDIATELY.  He will not refund or repair should you wait more than 2 weeks to test your waterblock, and apparently he doesn't test them himself.

I bought 2 copper water blocks from him almost 4 months ago and let them sit on a shelf while I waited for other components (pump, etc.)  Not in a big rush to build this thing, everything had finally arrived and I put it all together saturday and IMMEDIATELY could see a small leak from one of the waterblocks.  I feel this would've and should've been caught by him if he had bothered to test them.

So now I have to risk trying to fix a $40 waterblock myself and if I screw it up, I'm SOL.

So I would recommend buying from someone who actually tests and guarantees their waterblocks.

I have setup 4 friends with this very same waterblock problem - no leaks so far...

I did have a small leak in one of my pumps though - he offered to replace it but I just caulked it a bit and it was fine.

As I say though you should ALWAYS test everything outside the case (in the sink) just in case. I like to let all my stuff run for a few hours in the sink to make sure it's not going to give my system a bath.
