Amp fan cooling without dc current in the 110 line

So I just finished renovating an old TV console, modifying it by removing the TV and adding shelves to hold my gear within it. While it has vents on the sides, bottom and back, I’m sure my amp will get super hot inside. So I’d like to put a little fan in the cabinet to cool it off. But I’ve always heard those little computer fans put a lot of dirty DC current in the AC lines, resulting in noise in the amplifiers presentation.
So question is, how to avoid that.

Hu, I've always heard fans put DC current into the electrical system. Maybe that's bunk. Does anyone know for sure

I realize that an amp in a cabinet is not ideal. However having a kid click the power button on and off but repeatedly isn't great either. Really kids and HiFi don't mix. But I don't live in a perfect world so I work with what I've got. The ventilation in the cabinet isn't too bad, just need something to give it a little extra cool. So how do the batterys work, are they always charging and the fan runs off the batterys. Where can you get one.

Yea I could put an exhaust fan out the back panel at the top. There's holes in the bottom shelf underneath where the amp sits. It appears the amp vents on the bottom and the top. I'm hoping cooler air will draw in through the bottom up through the amp and I can exhaust it out the top back
