Hi
Thank you for reaching Microsoft Community. I'm sorry to hear about the issue you are having on your Surface Laptop Go fan.
The Surface may become very warm during normal use especially when the device is under heavy load and also while installing updates. Device may become warm also when charging. These circumstances will trigger the fan to run to maintain the device temperature within the limit. This behavior is normal. However, it complies with the user-accessible surface temperature limits defined by the International Standards for Safety (IEC 60950-1 and IEC 62368). If the device overheats, it will shut down and display a thermometer icon on startup (if not cooled). See: Product safety warnings and instructions (microsoft.com).
While the operation of the fan is normal and expected behavior, at no point it should be like there is something broken. Noises like grinding, whining, or ticking are abnormal. If you hear these types of sounds, please contact our live support for options and further assistance. You may contact them through the numbers listed in Global Customer Service phone numbers (microsoft.com). You may also reach them through this page: Contact Us - Microsoft Support and use the details or entries given here: I need to talk to tech support - Microsoft Community.
Hope this helps.
