Fits fine, you can even use the clips. it will overlap, so you have to do some cleaver placement, but it does work. if you dont want to do that though, just guy an oly 80 mm fan, screw two corners of it to your fan, and in the spaces that you didnt screw, you can use the clips to hold it on there. the clips slide between the spacer and your fan. so its pretty secure. might have to bend your clips a little for more retention.
i did this on my sk7, and again on my sk6+. works fine.
