I attached my Infinity to my AW9D-MAX using the Thermalright LGA775 RM:

and some ¾” long #6 socket-head cap screws.



I wasn’t concerned so much about overclocking as component fatigue. With the Infinity running almost twice the mass of the Intel reference design, I was concerned about the ability of the clips to maintain the necessary socket preload and about twisting of the motherboard around the socket.

I mounted the back plate to the motherboard after drilling out the 3mm tapped holes. I also filed off the small bosses around the holes. Small cresent-shaped plastic “washers” were made to insulate the ends of the back plate and to stand-off the plate so it doesn’t interference with the required motherboard deflection under the socket.



The heatsink clips sit on 0.1” “spacers” that I cut from 3/8”x 1" Nylon bushings. I original cut them using a X-acto Razor saw and miterbox, and then sanded them for hours, (or so it seemed.) Then it occurred to me to chuck them in my drill press and cut them out using the tip of an Xacto knife. I used one good one as a tool rest and cranked out the rest in no time. The 0.1” corresponds to the stand-off of the reference clips. Since I don’t know how to properly calculate or measure the required 18 –70 lbf preload needed to protect the solder joints in the processor socket, I’ll assume that Scythe factored that into the clip. If you're interested in increasing the pressure on the HSF/processor interface, you could use thinner spacers.



I wanted to mount my Infinity to exhaust out the top of my Antec 900. It just fits, but I’m crowding a couple capacitors, here:



and here:



The ¾” screws are a little long, but I drilled access holes in the motherboard tray so it wasn’t an issue. The next time I remount it I’ll probably trim them with a jewel's saw. (It make very clean cuts that won’t mangle the threads.) I think that using an allen wrench to reach under the heatsink and a nut driver from under the motherboard is actually easier than the standard clips, (at least on the MAX).



I did notice that I’ll need to be more careful with the alignment while I’m tightening the screws. (I had actually started to install push nuts to hold the screws in alignment, but removed them after reading the recommendation for rotating the HSF after it contacts the TIM. I’m reconsidering that option for the future.
