I put my heatsink on my Abit IC7 Max3 last week & am a little concerned with temps. Anyway following the Thermalright web instructions it looks as if you put both plastic washers onto each individual standoff before you screw it into the x-plate underneath the motherboard. This is the way I did it.

I looked at a review tonight & it looked like a set of plastic washers were mounted on top of the x-plate below the motherboard ?

Anyone tell me how they have theirs?

I would change it if its wrong but don't want to just try it for the sake of it - cause it'll take too long to do
