I have a Thinkpad T420 – now 2 years, 6 months old.  Started to notice the fan seemed a bit noisier than normal and the CPU was reporting a temperature of around 60deg C, even when the machine wasn’t doing very much.

As suspected, 30 months of usage without a clean is a little bit too long.  Cleaning a laptop fan can be fairly straightforward – this took just two screw removals.  Of course, always seek advice and YouTube videos if you need help to do yours! 😉

After the procedure, my laptop runs about 10-15deg C cooler and is much quieter.

Laptop keyboard removed – initial inspection

A closer look

And even closer to the cooling fan – covered in dust!

Apply some of this – compressed air

And there we are – a clean fan!
