Rusty fan screws

[Nautilus31]

Hello everyone.

I noticed two rusty fan screws at the left side of the lower front fan (behind the front fascia). I mainly use (used it thrice on this system) an air compressor to clean my computer. Could this be related to humidity Any ideas would be very much appreciated. Thank you.

Additional information: my computer is water cooled. No signs of any leakage.

Most likely humidity, yes.
You live near the ocean?

Thank you very much for your answer. Yes, I live near the sea. I thought it was from the air compressor because it doesn't have a water trap but it seems that mostly comes from humidity. Oddly enough, the computer case screws are intact.

For now...
My pleasure.

Do you really think I need to a attach a water trap to my air compressor, or should I continue using it without one? I'm afraid without a water trap, the compressor can convey moisture after a period of use.

You probably won't need it since compressing air actually heats it a little which should take care of any moisture.
