blown due to heatsink not mounted flush.

The board bends quite a lot when one puts a processor cooler (d805) on it.
So the center 2 of 4 FETs are not touching the heatsink (the one with the heatpipe coming from the south bridge chip.)
In fact they weren't even touching the sink before mounting the processor cooler, because when i removed the FETs heatsink there was no thermal paste on the 2 center fets and the paste on the bottom of the heatsink was untouched.

Now, this could explain why lots of people are having power issues with these boards. In my eyes this is a design error.

Does anybody know with which type of fet i can replace the 2 blown ones?

Then what's the purpose of having 8 phase power and why does asus say it's supported?

But that doesn't answer my question about the FET's replacements

How will i get them to replace it?
It is working, although only on 6 of 8 phases.
Which means power is fluctuating almost 0.2v going from light to full load.

I could offcourse try running it without heatsink, it'll probably not like that.
