Temperature and Humidity

I only use Umai bags in my kitchen fridge and they work extremely well for Coppa and Bresaola.
My newly acquired wine fridge does not go down to the temperature of the kitchen fridge so my method will not change. I am thinking of fitting an adjustable inlet and an outlet with computer fan for some air exchange to circumvent mould build-up,
The wine fridge will be used for salami in natural casings though.
