Lenovo X270 excessive heating and fan activity

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

Thanks MASQ, will try.

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

☠ MASQ ☠

" 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.
