yeah, mine does that too. Usually on days when its about -10 or colder. I will hear kind of a wind-howling noise as if it's coming from behind the console or its a bad-sounding fan. After the car is warm, the noise goes away.
As well, I get the speedo jumpin-around as well if its a bit colder. Doing about 50kph it'll just sail up to about 120 or something. looks really funny
But, like the howling noise, that goes away after the car warms up.
One of those things I'm just too lazy to fix, so I deal with it
