Hi Paul,
we replaced all fans of our frigoboat fridges with: epm-pabst fans 4412FGL: DC Fan, 12V, 120x120x25mm, 55.3CFM, 1.3W, 26dBA, Wire Leads and added screens epm-pabst LZ60 to prevent the dust get into the fan itself, because that is what killed our pantry fridge fan. We bought em here: https://www.alliedelec.com/product/ebm-papst/4412fgl/70105044/?keyword=70105044 https://www.alliedelec.com/product/ebm-papst/lz60/70105471/?keyword=70105471 be careful which way you mount the screen to the fan so the blades don't scrape (ask me why I know...). These fans are so much quieter and provide at least the same amount of airflow. We choose to blow air outwards of the cabinets in the hopes that there is less dust coming from the bilge area. If you would choose to blow air towards the condenser it would be easier to clean the dust off the screens with a vacuum occasionally. If I would have to redo the fridges I would go for it. I agree with Bill K. that the direction doesn't really matter much from an air temperature perspective. The dirt on the condenser fins is the bigger issue. kind regards -- Michael & Robyn SY RIPPLE SM2K # 417
