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
I highly doubt homeassistant will ever abuse the pi4 CPU enough to make active cooling necessary. As long as you have a heatsink of some form on the SoC you’ll likely be perfectly fine. Obviously monitor it for core temps once installed.
Remember the Pi uses the entire PCB copper ground plane in the board as a heatsink too.
