The 100m fan fitted to the Shuriken has two sets of fixing holes - one for 100mm and one for 92mm - and the supplied fan clips actually use the 92mm holes. So replacing the stock unit with a 92mm fan is a straightforward operation with this cooler.
I put a 25x100mm fan on my Shurekin. In order to do so, I had to cut the posts. I just eyeballed it right now, and it is pretty clear to my eyes that, at least my Shurekin's clips are 100mm ones. I remember trying a 92mm fan on it and having problems... one of which was that it just didn't work well with the plenum.
I must say, that Shurekin disappointed in so many ways. The reviews looked so good, but I found reality not so good.
