My intake is blowing cold air into my room with the storm blowing, it's 20 below outside and my heaters can't keep up. Looking into motorized dampeners to stop the wind. I thought about the spring loaded dampeners but I don't think it'll work as I have one on my outtake and it stop coming in but when the fans turn on it opens. In reverse it would just allow the air to enter in strong winds. Any advice would be appreciated.

turn it off for the nite?

If the fan's off, and the wind is pushing air in, then just figure out some way to plug it up. Shove a towel in the hole, screw some plywood over it whatever works. You need something to temporarily fix the problem today. Then you can add a motorized damper later.

Got it plugged up. Back in the 60's (lights off) again. So safe for the time being. But for long term is the motorized dampener the way to go? Any recommendation as far as brands? Look for something that seals up tight so no more air comes in?
