I just cleaned my pc for the first time in over a year and after plugging it in and turning it on the front 2 intake fans arent spinning only the back output fan is spinning faster than usual. It was fine before i cleaned it but idk what caused the problem and how to fix it. I used a can of compressed air to clean it and i didnt take any parts out. Need help quick pls
 
Solution
gently pull one of the fan wires and see if you can spot the where its connected to, as long as the power supply switch is off you don't have much to worry about safety wise, you can also gently take out the cables in the back as they are mostly extra cable and figure out the connection the fan has.


How are they plugged into the motherboard? Molex, 3pin/4pin? Were they even working to begin with?

follow the cables of the fans and see where they are connected, if its to the motherboard see if the connector came out, if it runs to the power supply or to a fan controller, check to see if the they are connected properly. If the two intake front fans have stopped working I am guessing that they are connected to the same power source and came loose.

I followed the cables and they lead to the back of the case near the power supply but im not sure where they’re connected because there are wires in the way
