We have a Lenovo X270 that is excessively heating up and often times the fan kicks in even when it's not at peak usage.

Open the case, use compressed air to clean out dust from the vents and the CPU fan.
Check heatsinks and thermal pads/paste are connected.
Reassemble and test again

I'd also check if the System is fully updated with System's low level code such as BIOS/Firmware.

Normally I would not dare to disagree with Masq, but in this case I do on the specific problem of clearing the air passages.

My experience with compressed air in laptops has been pretty much uniformly bad.  Blowing compressed air in through the tiny duct ports just compacts the mass of hair and dust worse than it is.  In these situations I open up the case, tease the mess out with dental picks, then remove the remaining dust with a small vacuum.  I/M/O vacuum works safer then pressure.

As for the fans ... laptop fans are just not built at the standards that they should be.  They are usually rifle bearing -- and when "ball bearing" is advertised, they have one or two balls.  Not good enough.  This means they wear prematurely since they are in a hot environment, the lubricant leaks out, then the lubricant attracts dust and dirt, and pretty soon the fan is shot.  Replace the fan while the case is open regardless of whether it appears to be working properly or not.

" I would not dare to disagree with Masq,"
LOL - this is hardly heresy :)

If the dust is that bad it's certainly easier to remove carefully by hand. My experience with compressed air without opening the case is similar to yours which is why I only recommend clearing it with the case open so you can directly see what's happening.
