We need to work the 2724 in a office room.

The 2724 has a fan which is very noisy.

Is there a possiblity to change the fan?

1. Change it to a silent fan (we have some)

2. Change it to a silent fan with temperature feeler (we have some)

3. Decouple the fan from the chassis with gumi flat washers

I we do so. Does we violate the guarantee with one of the changes (1, 2 or 3?
