Potential fix for PS4 Pro Coil Whine problems

Hey guys I’ve recentely stumbled upon a youtube video in which the creator claims to have the solution for (some) PS4 Pro Coil Whine problems. The solution in the end of the video was that the solder points on the board of the PSU get dried out by the fan which causes problems for the coil. Now im not very comfortable with this kind of stuff so i wanted to ask you guys here if you think this might be a valid solution ( he suggests to resolder/ reflow the solder points to fix the whine).
If you wanna watch it yourself, here is the link to his video. h. ttps://youtu.be/UVBaajn8wwc
