How to lower humidity in wineador

Hello everyone. I am new to the site, sorry if there is a specific area to introduce myself.

I have a Whynter 251s wineador. Capacity of about 400 cigars. Seasoned and was holding well. Stuck at 70% rh according to 3 calibrated hydrometers. 2 Govee lite Nmand one boveda butler.

I have 12 65% boveda packs inside and 2 fans running inside. One on bottom back wall pointing up, and one on top pointing toward glass. This has evened out the wineadore from top to bottom rh.

I have it set on highest temp of 66 and currently reading 63F ....

I ordered 2 of the 320 gram 65% packs and will try those in there as well. Any other suggestions? Thanks in advance!
