hello, I have bought a 2007 mac mini for very cheap from a yard sale and I have been running it 24/7 for the past few days. It does very little other than rarely seeding torrents and its CPU usage always stays very low. I have installed iStats and it reports the temperature between 60-70C at all times, which confuses me because it is mostly idle. The fan is around 2000RPM at most times. The fan works but makes a rattling noise like a cd drive spinning but I dont think that is a problem since it spins. I am okay with the mac dying after some time but I am not okay with fire happening from running at these temperatures 24/7. Is this a real concern? Am I bad to let it run 24/7 like this?
