Allsky: cooling my Raspberry Pi

The Pi 4 can get very hot.

When it does, it throttles the cpu.

So I've been working on a solution.

Linux Mint: my cpu fan is roaring!

This is a very recent problem.

 I'm pretty convinced it was caused by a recent software update.

Lubuntu 14.04 upgrade

As Linux upgrades go, this one was pretty painless.

 

Since fully switching to Linux early in 2008 I've been through some good releases and some not so good.

Sometimes it is down to your hardware, and how good or bad support is for your particular wireless module or graphics card...
