I've been searching around for a possible solution to this problem, but didn't find anything major dusts trapped within the fan housing. The noise is especially pronounced when I plug in the AC, not so much when I'm using the battery. I downloaded fanspeed to monitor my pc's temperature, and found it to exceed 180 degrees F when running memory intensive programs, sometimes staying at around 200 degree F, in short I can feel alot of heat being emittied through the keypad. The noise is annoying and I believe the fan to be the main culprit, however I read somewhere that an AC malfunction is a possibility. The laptop is at factory settings, although I did uninstall lenovo power management to fix an exisiting problem before. Does anyone have inputs?

SOLUTION: Go to support/downloads and download and install the May 2011 Bios Update Utility 2.27 and the Power Manager 1.99g. Lenovo has finally fixed the temperature fan control bug.
