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.
Remember the Pi uses the entire PCB copper ground plane as a heatsink too.
