Rampage III Gene fullcover waterblock?

[MrToad]

The only thing I can think of is that the block is shorting out or causing an open circuit on the board with pressure when you tighten up the block, It could be that is it miss shaped in some way. If you have fully insulated the block pressure can be the only issue I can see. I take it you've try using washers on the screws.

Yep, I'm using the supplied nylon washers on the screws...

Gonna change the thermal pads just in case they have absorbed some kind of metal residue (after all I was modding the case in the same room) and that's what's causing the issue...

Righty, second R3Gene down... I've tried every possible mount I could but in the end the board no longer boots... permanently...

Good thing I took insurance against accidental damage when I made the purchase so both the block and the board are going back, maybe I'll get third time lucky when I receive the replacement ones...

You did remove foil from thermal pad, right?
