Maybe......... I have seen people use a 150w HPS in a mini fridge on multiple occasions, however, most if not all were vented with a inline.
But who cares
Digikey has a ton of DC centrifugal blowers
If you are wanting to run 3-5 air space changes per minute in a 3.5cfm mini fridge, even a 150cfm is way overkill! and won't get much better even with a voltage dimmer [fan controller].
Do not trust the cfm rating on 12 volt fans. They ALL lie. The descriptions are so wrong the inaccuracies are measured in degrees of deception.
Count the amps -- ignore the cfm.
In my experience, they all SCREAM like jet engines, they really do. Most people on ICM are not going to be happy with that sort of product.
