I got a Thermaltake Big Typhoon a few months ago on sale at my local electronics dealer. I have 2 cases which I am looking at; the aerocool aeroengine 2 and the aerocool extremengine 3T. Will the typhoon fit inside of either of those cases? Also, is it worth paying an extra 30$ for a 25cm side fan instead of 2 x 120? Will I notice the cooling difference? Thanks for your time.
