Why does my car sound like a semi truck at slow speeds in the heat?

Anyone's cars ever sound really load at times when your driving at slow speeds? Mine gets very loud, almost like its sucking in a ton of wind when its hot out and I'm in stop and go traffic.

It's your mechanical fan...it's triggered when your temp gets to a certain level (don't know what exactly the temp is). Mine does the same thing....slowly dissipates the higher gear ya go....usuallly is totally gone by the bottom of third....correct?
