Many vent fans are made to basically lay on top of the ceiling drywall, using bend-out tabs in the metal box to clamp the box to the drywall. I wouldn't worry about the weight.

Is it ok to support a 10.1lb ceiling exhaust fan using a 2x4 on top of drywall rather than the provided metal brackets?
The metal bracket is to be used if fastening to a framing member (Joist or truss) is not possible.
The way your fan is mounted, ( assuming it indeed is attached to a truss) is preferred. You are fine.
