The more I think about it, most laptops nowadays have cooling systems installed this way. The pull air through the case, from the bottom, across the CPU heatsink, and out a port on the side.

It's intake and exhaust either way.

I would think it would just depend on how the airflow works through the rest of the case. If you have other case fan(s) that are directing hot air out of the case sufficiently, I wouldn't think anything of it.

After working on it this morning, I noticed the blue LEDs are no longer functioning (the red "write" LEDs are working). There's some oxidation on the PCB but none on the HDD, so it appears this unit was damaged when I bought it and I never noticed. |

It will work to cool it, but you would almost have to test to see which way is better.
One thing I can throw out there is that if you take apart the case portion of it, and you can see anything exposed that is having air driven over it to cool it, you can buy some very cheap and low profile copper heat sinks that stick on with thermal tape, the passive cooling combined with ANY airflow should be better than what you are getting at the moment. |

I ended up ordering a new one anyway, after finding the oxidation on the PCB. |

It's still going to drag air through to ventilate. If the fan is pulling (intake) it's going to exhaust through the side (or back... narrow end, whatever).
It changes the direction of airflow, but should still be flowing. I doubt it's so well engineered that it will make a difference.

I found these small fans to be so ineffective that it's only worth having them if you are in a really close space with no moving air at all. I've checked the temperature of a hard drive and found that removing the sides of the enclosure results in very similar temps.
The external casing is decoration that trap heat. If you don't need the decoration, then just remove the shell and don't worry about having the small fan at all. FYI i believe i have the exact HHD enclosure, blue LEDs and all. The fan went completely bad on mine. I disconnect the LEDs and remove the sides of the shell. Still have the frame, it's just open now, works fine with any fan. JMO

I really can't leave the case off, it's not just decoration, it also protects the drive. |

I think creating negative air pressure in the enclosure creates the best cooling.
I can't find the link now, but I found one that said that 1 fan exhausting created the best cooling. |

Right now, it's functional and I can feel a tiny bit of warm air coming out of the front grill, so I believe I'm getting at least some cooling. My new enclosure will be here on Monday. |

It's normal for smaller devices with only 1 fan to have only intake and then a grill for exhaust. Makes no sense the other way around.
