Macbook (alum) fan noise

I upgraded my hard drive yesterday and now i notice that the system fan runs continuously from the moment i wake from sleep. I checked the speed with iStat Pro and it's only running at about 2000rpm.

I searched the forum and went through the steps of resetting the PRAM and SMC. I even reinstalled OS X, but none of that seemed to help. I searched the Activity Monitor for stray processes, but there are none. Any other ideas?

Macbook (late 2008) 2.0Ghz, Mac OS X (10.6.2), Seagate Momentus 500GB 5400rpm hard drive

That's normal. It's the default speed designed to run at.

Install smcFanControl and you can manually adjust your fan speeds. (not below the default level though)
