[QUOTE="hughvane, post: 1920845, member: 56231"] Back to this heating topic - after running a few YouTube videos on a warm evening, my 2018 Mac Mini was very hot, more than I can recall it ever being before. It was too hot to leave one's hand on the top surface for more than a few seconds. What bothered me was that I could not hear the internal fan, something that's been a regular feature. I started up the external USB fan to assist cooling, but it seemed to make little difference. I was interrupted for some hours, so I shut the Mini down, and returned to it this morning to run iStat. See attachment (those readings are ºC should anyone be wondering). That to me appears normal, but the temperatures last evening were way higher, but not measured (iStat trial period had expired, renewed this morning). How can I determine - other than noise - if the Mini's internal fan is operating; and might it help to elevate the front edge of the machine? At time of typing, the fan was not operating, the top surface of the Mini felt 'normal', ie. slightly warm. [B]Update[/B]: the second and third screenshots are the more telling, #2 taken mid-morning, warm in the room @ 26ºC; then #3 after gaming mid-afternoon, during which time the internal fan decided to join in, clearly audible. Note Exhaust reading in #2, nothing. Following vacuuming of the air intake gap, a YouTube video running, no sound of the internal fan. Resorted to using the external USB fan, with front edge of Mini elevated by ~5 mm. Top surface of Mini warm, but not alarmingly so. [/QUOTE]
