Constant Fan noise from my ice cold MBP 15''

[Politis]

I think my fan is on ALL the time, even when there are no applications running and when my MacBook Pro 15'' is cool as a cucumber. There is a constant windy noise from the upper right hand corner.

I am aware of advice to reset the System Management Controller (SMC) (here, http://support.apple.com/kb/HT3964), but the recommendation is that an SMC reset should only be attempted after all other standard troubleshooting has been performed.
I also did a 'fan noise' search on MF, but the links were about overheating. I do not have this problem (touch wood!)

Is my fan stuck? What can I do about it? Thanks

An SMC reset will nor harm your Mac or your data and can be safely used.
Have you downloaded a fan speed monitoring program like iStat Pro to see the fan speed(s) of your Mac?
Know that 2000 RPM is the idle speed.

Thanks for that.
How do you download the speed monitor? Do I download it from, for instance http://www.islayer.com/apps/, or http://www.apple.com/downloads/dashboard/status/istatpro.html ..... or is it already available on my MBP?

I have downloaded it from iSlayer, it is a widget for your Dashboard. But you can also download it from Apple if you want.

OK thank, I just downloaded it from http://www.apple.com/downloads/dashboard/status/istatpro.html. It says my fan speeds are 2000 rpm, which you say is neutral.

The fans ARE always on in a macbook pro, else you'd only be using for 5 minutes at a time before it overheated and shut down, even on idle.
