Yes I know another post but I got to get this right.

I have the RBI 32qt 4 tub rack. Herpstat II thermostat set on 95.5 degrees. Fan circulating air on rack. Tubs 2 and 3 are divided into halves 1 baby on each side.

Current conditions are as follows:
Tub 1. Amb Temp 73.0 Hot 89.2 Humid 58%
Tub 2. Amb Temp 74.8 Hot 84.9 Humid 82%
Tub 2. Amb Temp 73.0 Hot 83.8 Humid 60%
Tub 3. Amb Temp 75.4 Hot 86.9 Humid 54%
Tub 3. Amb Temp 72.9 Hot 89.2 Humid 47%
Tub 4. Amb Temp 72.9 Hot 89.4 Humid 61%

Thermostat probe directly on flexwatt. Unprinted paper as substrate. Small water bowls on cool side. I have tried every scenario with the holes in the tubs but all seem to keep the humidity high. The Temp in the room is 74-79. Humidity is around 43%. Accurite thermometers in every tub. Heat gun hasnt arrived yet in the mail.

Is having a fan circulate on them all the time bad for them?
Do I need to get new tubs and drill less holes?
At my wits end here I dont know where to go from here. Sorry for the repost but I had to try and get some more suggestions.
