My Xiggy fan has never done more than 1300rpm even though it stated on the box to be 2500rpm, now it's always kept thing's cool enough, temps are usually around 35 - 40 at idle and around 50 - 55 on load, now to me that's doing a pretty great job as my CPU is overclocked to 3.4Ghz @ 1.45v - 1.5v on a 125w chip 
anyway's just wanting something that can keep it even cooler as it's coming to summer and thing's are guna heat up
