If it has metal blades then it will reflect some of the radio signals, making the transceiver more directional. With how it’s set up in the post, it could potentially be a benefit to devices that face the front of the router and fan, but a disadvantage to devices behind the fan. Same logic with that Facebook trick of putting tin foil or cut up drink cans behind the antennae.
However, most newer and higher end routers use beam forming antenna arrays which are already directional and can automatically focus the signal toward your devices. Having reflectors around those can actually interfere with the antenna array and decrease speeds for all devices.

Next you’re going to tell me having the microwave on slows my WiFi down!
Facebook lmao. That trick was around decades before Facebook.
