How frequently should a system be opened and blown out to clean
accumulated dust, etc.? The system is used daily, being on about half
real time.
Depends on the environment, and how hot the system is running.
With two cats, and living near a high traffic street, I usually
clean the cpu heat sink every three months. I have an app that
monitors the cpu temp, and whenever it gets over 55C, it's time
to clean it. When it's clean it usually stays around 48C. That's
with boinc/setiathome running, so the cpu is always at 100% usage.
What is considered a good/bad temperature for a system will vary
a lot depending on what cpu is being used.
