Do you have any link saying this

It works on 2800 but not in 1800

1800 and 2801 does not have a temperature sensor.

2811 and bigger models do have.

This is the way it is.

I think you have misread the document. It does not says that the 1800 has a temperature meter, it simply says that the FAN is temperature-controlled:

Cisco 1800 series fixed-configuration routers have an internal multispeed fan that provides chassis cooling, controlled by an onboard temperature sensor. The internal fan operates at a continuously variable speed to minimize fan noise while providing sufficient chassis cooling.

So you can go around as much as you want, no thermometer, sorry.
