The norm for cooling a computer is blowing air into the machine, so this also blows dust into it, which can coat the electronic components and cause them to run hotter, so run a vaccum round the inside once in a while. The RiscPC has this horrible design where the air is first blown through the hot power supply before it reaches the motherboard, ive wondered if this does more harm than good, modern computers also appear to do this.

When you switch the machine off this turns the fan off and even though the electronics are now off they still have heat in them, which can cause them to suddenly overheat even though they have no power in them, then finally cooling to ambient. The solution can be to simply never turn your computer off, once again this is a bigger worry with modern power hungry computers.
