No. Usually AC motors do not give interference since you are not using
speed control chopper drives. DC motors with brush will give interferece
But even DC motors have brushless type now

Try Sim Lim Tower not SIm Lim Square, there are shops on 3rd and Basement
which sells these stuff
They cost only $ 5 ~ $10 ... Even that I consider expensive.
Dot pay $35 for a fan unless you want to chat up the sales girl in mini
skirt

The cost price of these type of fans (consumer product) is ~ $ 1 to $2
You see the mark up by the distribution chain. But that is how business is
run
