It sounds like your PlayStation 3 is reaching the end of its life. I am fairly surprised you've lasted this long without the YOLD (Yellow Light of Death). My Fat PlayStation 3 lasted no where near 7 years before I had to start applying thermal compound to it. That being said, applying thermal compound to a PlayStation 3 isn't a long term fix. I had to use a heatgun on the CPU/GPU and reapply thermal compound at least once every two weeks and sometime within the same week and it eventually got to the point that even with the fix the fan would run at really high speeds and was very loud.
Also applying a new layer of thermal compound may not even work in this case as it is likely, given the age of the console that the CPU/GPU are too far gone by this point that the fix would simply do nothing.
7 years is a good run but it looks like your PlayStation 3 is on its last legs.
