Usually it is caused by dust accumulation on the fan after being used for a period of time. You can try to use a brush or discarded toothbrush to clean the dust on the fan blades; or it may be due to the processor's heat dissipation silicone grease being dry and cracked, resulting in poor heat dissipation. Therefore, the fan needs to run at high speed for a long time. The following is a detailed introduction:
1. To clean the processor fan, you can find a brush or discarded toothbrush to clean the dust on the fan blades, or you can use cotton swabs Wait for cleaning. After the cleaning is completed, the heat dissipation performance of the processor can be effectively improved;
2. It may be that your notebook fan is damaged, so you can only replace the fan;
3. Re- Apply thermal grease. After using the notebook for a certain period of time, you need to replace the processor's thermal grease. Thermal grease will become dry and cracked due to prolonged use, which will reduce the heat conduction performance. Re-apply the thermal grease so that the processor and the radiator are tightly integrated to fully take away the heat from the processor; it should be noted that the thermal grease needs to be applied evenly to avoid uneven application and the generation of bubbles;
4. The vents of notebooks are generally relatively small, and it is difficult for a normal heat dissipation base to blow outside room-temperature air into the notebook and take away the hot air. You can try using an exhaust radiator,
