Until the AeroFlow's fans are sorted out you can count that out of the picture ,I've been waiting a good few weeks for there to be released but Coolermaster has had to take back all the stock and find out the issues with the fans before they go on sale , also there is supposed to be a larger fan version of the same design so I look forward to that coming out and performing better.
I'd also point out you can get damn good cooling if you spend $$$$, so you also need to ask yourself what you can afford to spend on a hs/f.
