Mining in high humidity area?

[momchilandonov]

Hello.

Winter is here and the temperatures start to drop to 0 or lower degrees Celsium.
I plan on placing my machine on the balcony which is surrounded by PVC(not open balcony). As temperature lowers the humidity rises a lot. I wonder if there is a possibility of damaging my rig machine - especially the new R9 290 from humidity and losing warranty? The temperature difference would be like 80 degrees maybe? The balcony is small like 3-4 square meters and the rig will keep it a little warmer than outside. I just want the rig to be cooled better and to be silent. My gpu is working at 83-87 degrees C depending from the room temperature.
