The faulty PS4 Pro had a clogged heatsink, so even though it has a Nidec fan, it was very noisy. I replaced the fan anyways with a newer one, since the old one vibrates when you spin it manually.
I also applied Artic MX4 thermal paste and pads to the PS4 Pro's heatsinks. The fixed PS4 Pro is now completely silent even when playing a full hunt in Monster Hunter World. Very worth it!
All clips were cut from much larger sessions, I selected the noisiest parts of the videos. The faulty PS4 Pro had a peak 76DB of noise coming from it, with an average of 74DB. Crazy stuff, it was unbearable to play with it.
Recorded using a Blue Snowball microphone. Even though the camera moves in the after clip, the microphone was in the exact same spot.
The faulty PS4 is a CUH-7115, while the non-faulty is a CUH-7015.
