Default 12V fan - electrical noise

Is a small 12V axial fan with a brushless motor likely to be a source of radio noise?

I am wondering because I would like to attempt a power ventilation experiment.

Default Brushless fans

are typically not electrically noisy. Where I work, we use them on some helicopters with extended instrument panels to help circulate air through the enclosure. We haven't had any problem with them interfering with the radios.

I installed a small "cyclone" avionics cooling fan this summer and no problem except for the little bit of noise it makes while running and you can hear a little whine in the audio on shut down. Worth is to keep the electrons cool
