A stripe of foam rubber or inner tube between wall and fan makes a huge differenceI have a 24" Wall mounted Tornado Fan in my grow space. Works great and have never had any issues. .
One thing to note though is be careful where you mount a wall mounted fan. The resonant sound carries through the studs into the house. Its mounted on a shared wall in my attached garage.
Even two sided tape helps
