As Gustin said... Usually when a fan begins making noise, it is time to
replace it. Opting for a a slight more expensive fan with better
bearings is often worth the expense. Any fan in the same form factor
would be sufficient. Just make sure you match the voltage/wattage of
the existing fan. Fans inside laptop cases are MUCH harder to get at
though, so I'd try the compressed air first.

Sounds like a fan with worn out bearings or the heatsink is clogged.
I would try blowing out the heat sink with compressed air.
The thinkfan package might give you better control (I have a t430).

Thanks again for the welcome and the attempts at fixing the external
hard drive problem at the meeting.
I'm having another issue since earlier this year.
At medium and low fan spin rates there is often a lot of whine and
apparent vibration. When the fans are spinning faster, I don't hear it
as much (the volume seems less and it does not always occur).
When I tap the laptop the vibration/whine seems to stop for a while
before recurring. To check if it was just other sounds covering the
fan noise at higher RPM, I played a video and paused it, while
watching the fan speeds (in Gkrellm) and listening. At higher speeds,
over 3000 RPM, I did not get the loud whine.
At medium speeds (in the 2000+ range) I often did, but not always.
Right now, at 1959 RPM on both, I hear some noise, but not the sound
of major vibration.
Laptop: Lenovo ThinkPad T420i 4 gb RAM
OS: Linux Mint 17 Quiana
Temperatures are in the low 40s right now, but sometimes approach
50 c.
Previously, I had Windows 7 something or other and Mint 14, the latter
was out of date.
Is this at all related to the BIOS or the OS, or is it a hardware
problem?
