ridiculously high fan speed

[trev]

Hey all,

So this problem progressed a lot over the past 2 days. I have a Blackbook, it's about 3 years old now and the fan speed has increased to a very high level. There aren't any programs running in the background, this just simply happens when I leave the computer on. I'm assuming it's because there is dust buildup on the internal parts, but it's odd that it progressed from being fine to the stat that it is in today in the matter of days. Is there a way to clean the inside? Apple technician to have a look at it? Any suggestions at all would be greatly appreciated. Thanks.

Trevor

was is it on? sometimes when i leave mine on my bed or something that is covering the air vents the fans kick in, btu it shouldn't do it when on a wooden desk or something.

just my two cents, but i'd tried an apple store to take a look at it
