I have a fan running 24/7 in my chamber. I am curing for the first time in my chamber some salami. My first question is will the fan running 24/7 cause case hardening if so how often should I switch the fan off 12 hours? 8 hours? every other day? if so I will buy a timer switch. my chamber runs about 52-56 F and Humidity is about 70-80 percent.
