A:Answer It is normal for the fan to spin at full-throttle and generates noise louder than normal while the computer is under heavy load, especially during the initial WINDOWS setup and WINDOWS Update installation. Also, the fan noise will be louder while antivirus software or malware are running continuously in the background. Please make sure the system was not compromise by viruses or malware. When system resource utilization is high, this will generate more heat than normal and tends to trigger the fan to spin at full-throttle and noise will be louder than normal. It does decreases or normalizes once utilization goes down. Also, set power options into power-saving mode.
