Hello there,
Here are some solutions for the fan noise:
① Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of the Main page, we will check if you need to update the BIOS.
② If updating the BIOS cannot solve the problem, please adjust the fan speed, some item model have the fan control function in the BIOS, such as SER5560,SER5500,SER5600, SER 5700,SER5800.
③ Please adjust the VRAM in the BIOS, sometimes changing the VRAM can also help.
④Overheating. If your PC is overheating, please check if the fan spins. You can also turn off the turbo boost. Adjust power settings: Adjust the power settings on your PC to optimize performance and reduce heat generation. Lowering the maximum processor state or using power-saving modes can help.
Go to control panel —power option—change to High performance— change plan setting—advanced setting —processor power management— change both 100% to 99% , click save.
⑤Remove the fan, clean it and apply a very small amount of nonconducting lubricant to the shaft and reassemble the unit.
It is suggested that you can contact our after-sales mailbox: support-pc@bee-link.com
