Update August 30, 2021 = The fans spin when it is required to keep the system temperature balanced. Guide to Dell Command Power Manager[IMAGE]
The daughters new Inspiron 3505 has no Thermal Management option in Power Manager?  The problem is the fan control and I believe Thermal Management is where the fan controls are set. What it does now is it leaves the fan off until it reaches a critical temperature, then the fans spins full speed until it cools and then they turn off again until it is critically hot again. This is my first Dell laptop but my previous laptops all had the option to set the fan to 'Always On' to better regulate the temperature. In Windows Control Panel, Power Options is set to 'Balanced (recommended)'. If you click on the battery icon next to the clock the slide is set to position 2 'Better Battery'. I moved the slider to best performance and restarted. The Thermal Management tab is still missing.Am I missing something?  Any advice, Thanks.[IMAGE]
