10am in the morning. A PC was returned from construction site due to virus problem. The CPU interior was filled with layers of dust. Even the processor heat sink is somewhat clogged.
Here how we clean it :
- Prepare a small brush and a vacuum cleaner
- Turn off the PC.
- Open the casing to expose your PC's gut, start the vacuum cleaner
- Use the brush softly brushing off dust on the motherboard, CPU fan and others with the vacuum nozzle pointed at the brush to suck up dust
- Do this until you clean the whole interior. Do not wet the brush.
- Clean the clogged heat sink by removing the fan from the top of the heat sink (CPU fan are normally attached to the heat sink by hooks or clicks. Use the brush to brush between the pillars of the heat sink.
(Refer picture below)
Additional notes :
- always use small brush as it can go in small gaps
- if you don't have a vacuum cleaner, do the cleaning outside your home/office as you will poison everyone else with dust otherwise.
- never turn on the PC during cleaning
