asus silent square

anybody know about it?
if you've got info on it post here

im interested in buying one because my current cpu fan is 40db+ and i dun like it.. keeps things hot... so im going to get an asus silent square to cool it down.. anything i should watchout for? im not completely sure if it'll fit.. im gonna measure my case width from cpu to clear side panel.. ive also heard its very heavy.. does anybody have/use one of these on their mobo? does it need extra support? did it completely remove a hung of your mobo from the weight strain?

i wanna know these things cuz a hot computer is much better than a broken one..
