Oh My God. . .

You just don't know. I had an MSI 3870X2 and I put the EK waterblock on it before I tested it in my system. The card locked up like crazy and wouldn't go crossfirex. So I ordered an ASUS 3870X2 and tested it without the waterblock and it worked fine. so I removed it and installed the waterblock and bam, G-card went crazy again. I followed the instructions for installing the waterblock but now I have about $700.00 worth of paperweights. And you can't warranty the cards once you take the fans off.

I took them outside and smashed them with a hammer. (2 3870X2's smashed into little bits)they were useless. the waterblock shorted them out. I guess I will try to sell the waterblock but at this point I think It'll get the hammer too. has anyone else had this happen to them when installing a waterblock on a graphics card? I know it is not my system. I have a spare 3870-standard(not X2) and I put it in and the computer runs great. that card is not watercooled and I am afraid to try to water cool another gcard, this is getting really expensive. I am 32 years old and a lisenced aircraft mechanic, I can follow instructions. Sorry for my attitude, just very frustrated.
