Fans are controlled by CPU temperature, not activity levels. They'll start spinning once the heat reaches a certain point. If you can't adjust the fan settings in BIOS, consider using software tools: https://voltcave.com/fan-control-software/ If the fan activates later, it might cause problems. Unless you're unsure, it's best to leave it alone.
A few Dell models might lack the fan control feature in the BIOS. For one of my Dell systems, I need to use Alienware software to adjust it. I’m not sure if Fan Control was supported, but I recall seeing a warning about potential conflicts, so I stayed cautious.
To ensure optimal performance you need the fan running at full capacity nonstop.
Activate the BIOS fan control override. On your Dell, this configures all fans to full speed. If it doesn’t work, switch to SpeedFan. It’s the only available method since other fan control tools rarely support Dell hardware. Make sure to enable the Dell support option in SpeedFan settings, as it’s essential for proper functionality. Once set, adjust fans to maximum in SpeedFan. This approach is a bit old-school but remains your best choice.
Any update on this? I've been facing the same issue for quite a while and it's especially frustrating when the fans go crazy like a car engine in class and everybody starts looking at you. (For context, I'm on a Dell Inspiron 14 5410 2-in-1 with an Intel i5 1155G7 and the fans just start up on its own when the laptop boots up with no CPU usage.)
