Well if your in for maximum cooling with lowish noise, that is an excellent fan, one of the best dba/cfm ratios ou there.
but from my understanding of the megahalems is that they are designed for excellent cooling, with a low and quiet fan, around 60cfm, so that would make a nice fan around 15dba, and a crappy fan less than 25dba.
Or you could go with the best of both worlds and get a fan controller and then you could have the coolermaster fan at super quiet and low cfm's for average work, and turn it up for maximum cooling while doing cpu intensive tasks. Also consider the silverstone fm121 because it has good cooling and comes with a fan controller
Just a quick note if you get the coolermaster fan that you mentioned above, get it from newegg, its only 9 dollars there instead of 14 (unless of course there is something else you want for tiger or shipping is more expensive)
glad I could help
didn't even notice you are from CA my bad, well they do have a CA site www.newegg.ca but from what I can find through the Canada site you can't get that fan, ohh well.
