Dust!

[engine]

I had cause to open the lid on the PC and was shocked by the accumulated dust built up under the processor fan.

It was blocking the heatsink's slots and probably making the fan work harder.

Without doubt, it won't be helping the processor MTBF.

So, here's Friday's tip of the day, open the lid of the pc occasionally and clear out that dust!

[jecasc]

And I will show you something different from either
your shadow at morning striding behind you
or your shadow at evening rising to meet you;
I will show you fear in a handful of dust.

T.S. Eliot (1888–1965). The Waste Land.

At last I understand what he was writing about.
