Has anyone done this before? I just got a fan and installed it into my LG still air incubator on day 14. I have an auto turner and don't normally have the cover off for more than 15 seconds at a time. I figured that people that need to manually turn the eggs several times a day have it open for much longer. It took my about 4 minutes to install the fan with the cover completely off. Temps have come right back to normal within 10 minutes. I have 18 developing eggs in there and have not had any problems thus far. I was reading about the improved hatch rates with a fan and decided to pick one up. Just looking for some feedback....
