PS4 PRO CUH-7116B JET Engine 2020 (went warranty replacement)
Update: This 7100 was my second PRO (after jet 7000) and Jet Engine went that bad that it was unusable, despite my efforts for cooling, my 7100 PRO was replaced by 7216B model now as was under 2 year warranty. (EU)
Now everything is dead silent, but time will tell how this third PS4 model hangs here. (2020)
7216B went bad 2021 and
fixed with new Thermal paste & pads, now again silent.
Because terrible Sony airflow design, dust building at CPU heatsink, also low quality dry factory thermale paste needs replacing.
Also good to change thermal pads.
Update 2021: My new 7216B is by far my best model now, Thermal paste Arctic MX-4 and Thermal Pad are Thermal Grizzly minus pad 8, also totally cleaned, machine is now quieter than what is was at new. also new power supply is changed and some coil sound is gone, but some are left, Days Cone has loud coil noise, Destiny 2 is silent almost.
