When you are doing any heavy task on your computer, the load in the CPU used to increase. Then the fan spinning rate automatically raised in order to cool down the excessive heat produced. The fan, here, works as a ventilation system.
For your CPU health, the fan is the most important part. The fan is always running on your PC. But at a slow rate, we basically didn’t get even a trace of its spinning. But sometimes the fan started running at high speed. So let’s see the reasons and possible ways to fix it when laptop fan making noise
Firstly: CPU Temperature

The CPU percentage increases when you do heavy tasks like video editing, playing a game in HDR, etc. And thus your laptop getting hot. And it’s obvious to be.
The fan will start running at a high speed. The fan keeps on spinning at a high speed until the temperature gets to normal.
In this case, you will notice a difference in the fan speed, sometimes very high and sometimes moderate. If you found the CPU percentage is high in the task manager and if it is for running heavy software, then it’s normal.

Secondly: Obstacle in Cooling Fan Vents
Sometimes dust or other particles attached in the vent. And it acts as an obstacle in the path of intake airflow to the CPU. That creates a deficiency of air quantity. The fan, itself started running at high speed to deliver the quantity air to the CPU, thus cooling it down. So this is the most general issue for why the fan started running at high speed.
Solution: Try to clean the air vent with a soft tiny brush or a rag. Check whether there is anything that creates difficulties in the path of airflow.
