For the past two weeks, my PC fan has been making a loud noise, which is unusual. I'm concerned that this could be a sign that my PC has been hacked. Could it be something else? What should I do?

It's likely just a buildup of dust or hair clogging the fan. Have you cleaned it recently? If not, grab some compressed air and give it a good clean.
Check how hot your hardware is; the fan might be running louder due to high temperatures. If you haven't checked your thermal paste for your CPU or GPU recently, it might be dried out and need replacing. Also, verify any background processes using a lot of resources—malware can cause issues too.
No, you probably haven't been hacked. Loud fans are usually just dust or a sign the fan is wearing out. Cleaning the fans should help, but if the noise continues, you might need to replace the fan.
Alright, thanks for the advice!
You seem to be overthinking it. Most of the time, noisy fans are just due to dust or a bad bearing, not hacking. Clean it, maybe check for updates, and monitor your system temps.
I cleaned the PC a couple of months ago.
