Dell Latitude 3330 fan control issue


New Member
Dell Latitude 3330, the latest BIOS A05, Win7 64, HWiNFO64 4.50
When I set a certain target fan speed in HWiNFO, it keeps it only for a second and then the fan speed goes back to the default (firmware) speed. What can be done?
I'm afraid, there's nothing I can do - the firmware fights against HWiNFO and unfortunately it always wins.. You should contact DELL.
I doubt DELL will help :)
BTW, the fan controller in this laptop is EMC4021. But it seems you don't control hardware directly.

Unfortunatelly FN+SHIFT 1,5,3,2,4 FN+SHIFT R combo does not work on this laptop. Does anybody know any other ways to get into thermal control menu?
No, I can only do what the firmware allows. Fan control is completely in the hands of the firmware of the Embedded Controller.
