Hello folks, have been looking around for high static pressure, high performance 140mm fans and found this http://www.silverstonetek.com/product.php?scase=c_140&pid=366&area=en

The fan itself, is fantastic. But for reasons unknown to me they decided to give it 120mm mounts, can anyone give me some advise as to how I might mount these babies on to a dual 140mm fan radiator (from Koolance, and in push pull, if that helps)?

Cheers guys :)
