Open up the case and clean it out and make sure that the fan is sitting right in the case.

Trying what vk3fcll said might work, and if not;

How old is the system? Perhaps time to replace it with a different fan? They tend to die after some time (although mine has been going for a few years by now).

I'd go for this Slip Stream fan that runs at max 1900RPM, and then slow it down to 1200 so you get maximum performance at a good sound level. And ofcourse then you have another 700RPM headroom if you need it.
