Wierd SMC-ish change in my MacBook.

Since 8 October, has there been any SMC updates? Because my MBP's fan is now constantly running louder than my harddrive, speedstep is off and the MBP is constantly at 2.0GHz even if its only at 2.5% of usage, and idle temp dropped from around 50-60 degrees to 30-40 degrees...

MacBook Pro, Mac OS X (10.4.8)
