Stop using compressed air on dusty disc drives, I learned the hard way
Last month my PS4 Pro started sounding like a jet engine every time I booted up Red Dead 2, so I grabbed my air compressor and blasted the vents from the outside. Big mistake. The dust just packed deeper into the blower fan, and I think I actually jammed a clump against the bearing because a week later the fan started grinding. I pulled the whole console apart, 20 screws later, and found the real issue: those little foam dust filters on the intake are what catch everything, and mine were completely clogged. Once I removed them, washed them in warm soapy water, let them dry for 24 hours, and used a soft bristle brush on the heatsink fins instead of air, it ran quieter than when I bought it. So my tip is, never point any high pressure air into the disc drive slot either, because I did that once on an old Xbox 360 and it blew the laser ribbon cable right off its connector. Has anyone else ruined a fan by blowing air the wrong direction, and did you manage to revive it or just order a replacement off eBay for like $15?
