Review on 80Mm Moisture-Proof Fan 2-Pack 12V DC 8025 High Airflow Cooling Fan 2 Wire 3Pin 3500RPM by Nelson Calafell

I bought these fans because they were advertised as waterproof. I bought them to circulate the air in a room with 80% humidity. I bought 2 packs (4 fans total) and after a month only 2 fans are still working. The problem seems to be cheap wiring. The first fan to stop working seems to have a wiring problem in the fan motor housing. The second fan has problems with the power connection. I have not touched or moved these fans since installing them. Why do wires fail? I guess it's only a matter of time before the last two fail me. Don't spend money like me
