watercolling

I need some help. I made a waterblock for my 950 athlon out of alum. Well my problem is that i burnt my chip. What I found was that my block was letting moisture through it . Do you think it is because that my water sit above the bottom of my block .100 . or do you think alum. suck. Im stumped. thank any advise

P.S. sorry about the spealing.

how thick was the aluminum? maybe it was a bad welding job.

What do you mean your block was letting moisture thru it? Did you mean you have a leak in the seam? I don't understand what you mean.
