Topic: Playstation 5 slim sitting flush with my table (horizontally)

Hi. For the past 18 months I have had my ps5 slim sitting as follows: https://ibb.co/fYYdk2Pw

I've noticed on various images online that the ps5 slim isn't meant to be sitting so flush with the table on the rightmost side. Am I doing something wrong? My Ps5 slim gets VERY hot, and, after turning it upside down, I've noticed it has yellowish discolouration on the bottom. I am very concerned that I've been overheating my PS5 slim this whole time. Can anyone guide me on what I might be doing wrong?
