A colleague asked me to check the fit of the EK-FC260GTX blocks to Zotac 260GTX cards as he's had three cards fail on him.

The only thing i can see that might be causing any kind of problem is about a 1mm gap between the block and all seven voltage regulators which seems a little excessive given that the supplied thermal pad as around .6mm thick which means that when the block is fastened down to the card there is no, or little contact.

Just wondering if anyone else noticed this and if it would be enough to make all three cards fail??
