Exhaust fan "Instant On" vs "Energy-saving" mode

The fan being on 24 hours a day is normal if you have the console in instant on mode.

Switch to energy saving mode if you want silence after shutting down

Hi, if you have instant on mode set in the power options the fan will indeed keep spinning, try changing to energy saving mode.

There are some drawbacks with energy saving mode though such as the Xbox will not auto update etc.

do you have your console on instant mode if so your Xbox one fan should turn off if you have your Xbox one is on energy saving mode it should turn off within 5 minutes

I've changed my console to energy saving mode, and I the fan now turns off. Thank you for helping!

Instant-On power mode

In Instant-On power mode, your Xbox One console is up to date and ready to use. In this mode:

•Your console automatically downloads updates.

•Your console starts up in two seconds.

•You can wake the console using a voice command. Just say “Xbox, on.”

Notes

•Your console may sound as if it’s on when downloading and installing updates.

•In Instant-On power mode, the console power supply unit (PSU) remains on and the solid white LED on the PSU is bright.
You may also hear the fan in the PSU.

•The console uses 15 watts of power when in Instant-On mode.

Energy-saving power mode

In energy-saving power mode, your console is shut down to save energy. In this mode:

•Updates are not downloaded and installed until your console is turned on.

•Your console takes 45 seconds to start up.

•You must press the Xbox button to start the console.

Notes

•In energy-saving mode, the PSU is in off/standby mode and the solid orange LED on the PSU is bright.

•The console uses 0.5 watts of power when in energy-saving mode.

My console also goes into "energy saver" vs. staying in the "instant-on" mode automatically. Bugs Suck.
