Required Materials
Before starting, gather these supplies:
– Compressed air can
– Soft microfiber cloths
– Small brush with soft bristles

Opening the Case
1. Identify case opening mechanism (usually thumbscrews or regular screws)
2. Remove side panel(s) carefully
3. Place screws in a safe container
4. Take a photo of the interior layout if you’re unsure about component placement
Cleaning Process
Start with the largest components and work your way down:

Spray from multiple angles to dislodge dust
Wipe blade surfaces carefully with a microfiber cloth
Pay special attention to the CPU cooling fan
Heat Sinks:
Spray between fins with compressed air
Use brush gently for stubborn dust
Ensure airflow paths are completely clear
