If it sticks in the open position, there will be insufficient pressure in the system, and the coolant will not get hot enough, reducing the heater’s output. Usually, if the CPU fan is broken, it will stop running. That software can control BOTH types of hardware RGB systems, depending on which type of header is included on the Gigabyte mobo. When the radiator stops working correctly, too much pressure is put on the thermostat, often causing it to stop working. When it does happen, you're left with a miserably underpowered heat or AC system. If your fan is still not working after you have tried all the above-mentioned suggestions, then a failing fan clutch could be the issue if you have a car equipped with a mechanical clutch. Thermostat motor is blocked OPEN (engine never gets hot enough to start the fan) The failure relay. Your engine cooling fan will not work if you have a blown fuse.

Incorrect Positioning: You should place your laptop on a firm level. Since power to the cooling fan is sometimes routed through the cooling fan resistor, when it fails or has any problems , it can cause issues with the regular operation of the fans, which can lead to overheating.
