Intake cold air during winter problems?

Anyone use a cold air intake during winter and do you have issues with condensation?

I got a 12 inch intake fan and 12 inch exhaust fan, the fans are 1700 cfm. I plant to use the cold air to cool my second room this winter. I got 6 de 1k lights in there, room is 12x24.

Just wondering if I'm gonna have any unforeseen problems, I plan to insulate the duct work to help with condensation.

@Renfro any experience with something like this?

Did this in my veg room last year actually. I ended up just proping the window open just a bit. I used a AC infinity fan too just set the temp and it will turn on and off. Then I took the fan downstairs lol. As for condensation it will drip its cold air going into a hot room nothing too crazy.
 
I posted a similiar about bringing in sub 32 degree air directly to the hoods. Would condensation form and short bulbs eventually or rust the socket?

I do this with 2 600s but I dump the cold air in front of an oscillating fan to cool the ambient temp, rn the tents at 75 outside 44. it does condensate and I need a pail to catch the drops. this is all obviously away from electrical

I do use cold air intakes, and yes you do get condensation on the outside of the duct / blower. I always use galvanized snap seam duct and I make sure that the location won't drip on sensitive stuff. Insulating the duct is an option. I don't run the intake enough to warrant that as it doesn't drip on anything but floor and it's not a puddle or anything.
