FAQ:

Q: Can an external fan cool a PC?

A: Your desktop computer generates heat as it runs, which can reach dangerous, component-killing levels inside the enclosed tower. Internal fans help dissipate this heat, but sometimes it may not be enough. External cooling fans can help keep air moving through the system and keep the temperature at a safer level.

Q: Why is my laptop fan not running?

A: If your fans are running even after you’ve turned your computer off, the issue may be caused by a residual charge left on your motherboard. To troubleshoot this you will need to perform a cold boot. Turn off your computer completely, then unplug everything — including the power cord — from the tower.

Q: Do I need a new computer fan?

A: You can also use a vacuum to blow out particles, although the prior two suggestions are your safest route, as vacuums can produce static electricity and potentially (but rarely) fry one of your components. If that didn’t work and everything else with your computer appears to be working fine – you need a new fan.
