I have been storing puer under similar conditions to what you have described for slightly more than ten years. In my puer storage area, I have experienced humidity spikes up to 80% at certain times of the year and my puer, both raw and ripe turned out none the worst. Meaning, no fungi infection and my puer tasted just fine as attested by my hardcore puer friends. I suggest you monitor the humidity in your attic for a longer period of time and observing your puer before moving ahead to install a dehumidifier.
