The loud noise of laptop fans is a phenomenon often reported by laptop users. Whether a loud laptop fan is normal or a real problem cannot be determined simply by hearing the laptop fan. Next, IT Encyclopedia will explain to you the main reasons and solutions for the loud noise of laptop fans.
Under normal circumstances, the laptop fan will adjust its operating status according to the temperature of the CPU and GPU. If there is light resource usage, the notebook fan is in standby mode. Therefore, we cannot hear the sound of the laptop fan at this time. When running professional design software or large-scale 3D games, because the temperature of the CPU and GPU rises rapidly, the demand for heat dissipation increases, so the notebook fan runs and adjusts the speed to accelerate heat dissipation. At this time, the laptop fan sounds loud, which is normal.
After talking about normal phenomena, it is now time to talk about abnormal situations.
1. If the laptop fan continues to work when the CPU is not under high load operation, it means that there is a problem with the laptop fan's adjustment system and the fan is in an uncontrolled state. At this point, you can try to refresh the BIOS to restore control. If the problem persists, it can be determined that the laptop fan cable is loose, causing control failure.
2. The eccentricity of the laptop fan causes the laptop to The fan is loud. Due to improper use, the notebook collides or the notebook is placed at an angle that is too tilted, causing the notebook fan axis to shift and the bearing friction to produce noise. If the laptop fan still sounds loud after trying to place it horizontally, you need to contact after-sales service for replacement.
3. Dust accumulation causes the laptop fan to sound loudly. After a period of use, a lot of dust will be absorbed inside the notebook, especially on the fan blades of the notebook. At this time, it is necessary to disassemble the machine and clean the dust.
After some explanation, I believe you can already judge whether the loud sound of your laptop fan is normal or there is a real problem. If you are still not sure, you can contact the official customer service online, and they will give you the most detailed answers based on your feedback.
