[Bf-cycles] Pause

I usually blow out machines with a shop vac with the hose on the blow
side. I have even used lawn
and leaf blowers as well, just be careful with that method because of
just how much air it creates.

Quite often large amounts of dust can build up inside heat sinks and
fans causing thermal issues,
especially if there are pets in the house. This can be very bad if there
are any smokers in the house.
I hate it when people bring me machines that have been in a smoke
environment. The smoke glues
the dust to every thing inside the machine like a sticky paste. In such
cases the entire machine must
be disassembled and cleaned with alcohol and cotton swabs. For heat
syncs that can be removed, glass
cleaner and HOT water work very well, but make sure they are dry before
trying to reassemble.

Make sure all the fans inside the computer are clean and spin freely.
Including the one inside the power supply.
Some times the bearings will seize up, and the fans will no longer spin.
Over the years I have worked on a technique
for disassembling, cleaning, and greasing the bearing in fans. This is a
very delicate procedure, so replacing the fans
is usually recommended. However, if you are good with your hands, and
have plenty of tools for working on tiny
things, you can restore fans to working condition. Works great for
quieting noisy fans that tend to growl as well.
