Are you gonna use the cards spare screw holes for fixing that sink with the mosfet's onto the card using dremel 'n some nuts and bolts?
Yeah I know what You mean, it's easy to shorting out things.
But I don't want to seal it, not yet because I've still some modifications to do.

I'm going to add 2 more PNP power transistors to stabilise the output/core voltage a bit.
As it is, the circuit should permit 6 to 8 A but I need more.
The highest stable voltage I can give my GT is still only 1.47V.
Anything higher, my card becomes less stable.

1.6V core voltage and fully stable at 450 core is my main goal.
Then I can seal it.

As for how to mounting it I've no idea, the heatsink can get pretty hot and it needs a fan.
But probably in a box, with a fan blowing on the heatsink lying at the buttom of the case.

Before the mod my GT refused to work properly with 1.4V.

'01 at 400/1100@1.4V before the mod ;
