The L9a definitely uses shouldered screws - I can't personally vouch for the L9i variant though.

It uses shouldered thumbscrews, too, similar to the ones of the L9a, but with a small plastic washer and a wider knurl part. That doesn't prevent them from being overtightened, though.

The length of the threaded portion would limit the tightening of the screw to a predetermined level (you cannot tighten past the end of the threads!). I would say the distance between the bottom surface of the board and the top of the CPU heatspreader would be the same (within tolerance) for all Intel boards.

That is correct, it is something between 8 and 10mm, IIRC. The mounting brackets of the NH-L9 coolers have shoulders as well, I'd say with those we are arriving at at least 5mm distance from the top of the board, which results in a bending angle of about 15° for the 75mm distance between mounting holes that sockets 15xx have.
I wouldn't call that healthy at all. Still, you immediately notice this during assembly.

Sorry to bring up an old topic but does anyone with an NH-L9i know what thread size and length for the screws that mount the fan?

I used M3x8 screws to mount the NH-L9i in the past, but I used rubber rings as a bit of padding, so M3x7 should be the minimum screw size you can safely use.

NECRO!

My Google-fu has failed me tonight. Does anyone know the the size of the IHS contact pad (between the brackets) on the NH-L9i?
