I’m making a homeassistant sever with my raspberry pi and and i’m wondering since it’s going to be on 24/7 that the fans going to wear out much faster than intended. I can’t imagine that I would need a fan ontop of a heat sink and thermal paste it can’t get that hot? I should also note that i’m using an Argon V2 it’s one of those heat sink cases that are made for raspberry pis
Small fans will wear out quite fast, but Rpi should be fine without active cooling most of the time. I have one rpi4 in 3D printer enclosure (no fan, just cheap heatsinks) ambient temp goes up to 36 C and never had problems even with 24h long prints.
