Well I measured the Width of the fans they seem to be 6.6cm or 66mm. This is from the front to the back of the fan. About 6mm of this is from the soft trim around the sides of the fan unit. But even with this taken off its still doesnt change the clearance enough. I may have to go back to a stock radiator to get this to work. Funny thing is If I did go back to a stock radiator the stock fans at that point would afford me enough clearance anyway, which makes having the FAL fans useless.
