I have an early 2011 Macbook Pro 15" 2.2 GHz Intel Core i7.
The fans are running extremely noisy, they sound like a motorbike.
I downloaded smcFanControl and I noticed that my left fan is running between 0 - 300 rpm, while the right fan is at 2500+ rpm.
So is the left fan pretty much dead and needs replacement?

Is your laptop hot at all?

Is this a mistake? If it isn't, something is terribly wrong with your fan.

Default base speed for MBP fans is 2000rpm.

Your left fan sounds like it needs replacement, making your right one work harder.
