Why is my Windows PC so loud

High CPU or GPU usage causes the fan to run at high speed. 2. Dust accumulation affects the airflow of heat dissipation, making the fan louder. 3. The background program uses the hard disk excessively and causes noise. Windows computers are usually caused by three reasons: First, running a high load program will cause the CPU or GPU temperature to rise, and the fan will accelerate and generate noise. You can view the resource usage through the task manager and turn off unnecessary applications; Second, long-term accumulation of dust on the fan and heat sink will hinder the air circulation, and regular cleaning or repair of compressed air can alleviate this problem; Finally, when you hear intermittent clicking or rotating sounds, it may be that the Windows index, update or antivirus software background operation occupies hard disk resources, and you can pause the index or adjust the scanning.
