   Heat is often about continuous utilisation, like CCTV. On my Pi4 I have   
   a heavy aluminium case that serves as a heat sink, it is fine without a fan.   
      
   On my Pi5, I use the official active cooler heat sink, which has a fan.   
   But a good fan, in that it only comes on during the hottest days of summer.   
      
   In a moment of stupidity I also bought a metal case for the Pi5 which   
   messes up my USB keyboard/mouse dongle (reflection?), I haven't checked   
   to see what it does to Bluetooth and WiFi.

   They do, but they normally last for years.
