im on the frozencpu and lookin at the specs the CFM for the fans you posted IS HIGHER BUT at a price of 20-25? thats ridiculous and you need 4 fans of that which is going to be expensive
can you gimme link to that yate loon fan , i cant find it.
note: when comparing fans, look at the CFM and the dbs (noise rating) then price, depends if u have money or not, but 20-25 dollars for one fan is quite pathetic
also do you care for noise levels? if not there are much more options for you
