You cannot manually control the fan speeds on any XOS switch, I guess if you get it hot enough you can make them go faster... 

Thanks Bill, in fact I'd like to set a lower speed, I guess fan speed is proportional to environmental temperature.

Hi Arman,
The fan speed on newer products is tied to environmental temperature and in some models, tied to processor temperature. Older products have a "binary" fan.
Which model(s) are you curious about and we can at least give you some insight as to whether or not the fan speed is relative to temperature.

Hi Arman,

If the fan is running at very high speed, there is a known issue related to this. I don't have the CR number available right now, but it should be fixed in the latest patch of EXOS 15.5.3.4, which is the recommended version for the X430.

What about the x440-24t:
- showing 0 rpm speed (all the time in "show fans detail" )
- but some devices we can see the fans working and anothers we can see fans not working

while x440-24p:
- showing 11000rpm (all the time too)

xos 15.7.1.4
