P9 No need to remove the HS/Fan,  I've used an air compressor for many years 
to do this job.

Tricks to note are.
1 Use a plastic 'stick' to stop fans rotating. Spinning them up beyond their 
normal speed often causes the bearing to start chattering  at next switch on 
(dry phosphor bronze bushes)
2 Heaviest dust is usually in the CPU Fan and Power Supply, do them first 
and predislodge with a long bristled brush. I use a basting brush from my 
local $2 shop.
3 Fan location: Power supply, CPU, Sometimes Graphics card, sometimes front 
& back of case and sometimes motherboard chipsets.
4 Do it outside, you don't know what the dust contains.
5 Watch for labels blowing off, check them in case they need to be re 
attached (model numbers etc)

The hardest ones to get clean are those close to kitchens or other 
envronments with  a lot of  fat or oils in the air, but the air pressure 
should be enough to clear them.

Printers can be cleared with air to, just watch for small flappy bits of 
plastic.

After blowing out wipe with soft rag to mop up surface dust.

Lube CD/DVD trays and printer sliding parts afterwards with Silicon spray to 
improve workability.
