It's tough to disconnect the fan. Just remove the 4-pin PWM connector—if it's a Molex or SATA type, take it out to check. If the noise bothers you, you might want to consider replacing it.
I was wondering why fans would hum at specific speeds. It seems like a faulty Arctic model. I suggest using a pipe—perhaps from a kitchen roll or similar—and try to locate the sound with it. That’s what was suggested when I attempted to diagnose the clicking noise from my PC. Turns out it was the external power bar.
It seems like you're concerned about potential issues with your system. Damage-wise, what could go wrong? Could the power supply unit fail? I'm not sure if the noise is coming from the fan or something else. I also saw somewhere that a similar sound might come from the MOBO, but removing the glass panel made it less noticeable when viewed from the back of the PC.
It doesn’t look like it. It seems something is affecting the fan blades. You mentioned unplugging the fan to rule out that, so maybe it’s a cable hitting them or a loose connection. If it’s the power supply unit, it might work temporarily but eventually fail, leaving your PC without power—no explosion, just a sudden shutdown.
It seems you're asking about whether the PSU fan is stronger than the case fan and what happens if the PSU fan hits something. The PSU fan might be more powerful, but its performance depends on design and load conditions. If it impacts a component, it could potentially cause damage, so always check compatibility and safety guidelines.
