  • Answer to: Clean Dust from Inside MacBook, fan?

    yup.. clean heatsink is the most important thing on your laptop. although i was dusting off internal parts of my mac, i never cleaned the ribs of heatsink. i was facing many problems like flickering of the screen, losing wifi connection, overheating... etc.... then i realized, i gotta check the heatsink, so i disassemble it, and there were big chunks of dust built up over the years now after cleaning, the mac works like new. unbelievable piece of hardware. here is the pic.
