Both devices are laptops. The old one had regular cleanups with a compressed air can. The new one is… new. I never cleaned it, but I figure it doesn’t require any cleaning one month in (I don’t live in the desert nor in a mine).

The new one is a thick thinkpad with a fat heat sink and dual fans. Its cooling solution looks much more serious than the old one, which only had a tiny heat sink and a single fan. It was also thinner.
