External fans for Norcold fridge

My Norcold has 2 computer type fans. I removed them when I did this mod as they just were not doing the job. Maybe newer coaches have 3 because of this reason. Hadn't seen the 200mm computer fans however I think I still would have bought the automotive ones as they are probably going to be longer lived in this application as they are made to not be damaged by water. Not that the area gets wet but it would expose them to high humidity on damp days. With the volume of air these new fans move,I'm doubting direction of airflow will make any difference. We camp year round so at the moment the fans are not in use here in the cool Reno fall. Hadn't thought about the flue issue. In testing with the snap disk jumped it did not seem to be affecting the flame. My short "testing time" probably didn't prove whether the airflow is going to also cool the flue and affect the cooling. Next summer will tell the tale. If needed I'll reverse the fans.
