PC overclockers/tinkerers...I have a question...
Last year I bought a Sabrent external HDD enclosure that includes a cooling fan. I thought it might help extend the life of the drive in the enclosure.

Today, I noticed that the fan was not spinning. After taking it apart, I noticed that the mounting bracket was poorly installed (and cheap plastic) so the fan was rubbing on the drive, stopping the fan.

Normally, a case fan of this sort (when installed in a PC or other similar device) would be mounted with the closed side (the housing with the label that doesn't spin) facing the computer case. The open (spinning) side would be facing in and normally would either have free space behind it or be covered with a screen to prevent something from interfering with the fan. Air is pulled into the open side and sent out of the case.

The problem with this thing is that there's precious little space between the open side of the fan and the HDD. On top of that, the mounting bracket actually has a built-in screen. After taking it completely apart, the fan actually fits better in the mounting bracket if I reverse it so the housing side of the fan is facing the HDD. Then the open side is protected by the built-in screen in the mounting bracket. It almost looks like that is the CORRECT orientation based on how everything fits together.

The issue is this:

With the closed side of the fan facing the HDD, I've reversed the airflow. I would now be pulling air IN to the enclosure rather than blowing it out. It does appear that the design of the enclosure would allow air pulled in to flow 2 or 3 inches and out the grill in the front of the enclosure.

So for those of you that have done a lot of work with PC cooling, should I reverse the fan?

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.

It's not actually a PC, it's a HDD enclosure.



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.

Not in this case, it's not. Take a look at that pic.

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.

There's literally no room for heatsinks. There's maybe 1/16 of an inch between the drive housing and the fan.

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.

The difference in drive temp between this enclosure and the aluminum Rosewill I used before is 25-30 degrees farenheit. When it comes to an always-on backup drive (it's actually backing up my NAS), the fan makes a HUGE difference.

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.

Certainly if outward flow is restricted, pulling air is not providing significant cooling because it's the movement of air over the surface that is providing heat transfer.

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.

I have a Synology NAS with 2x2TB WD Reds in RAID1. Stores all my comics/movies/music and streams to anything with a browser in or out of my local network. At home it's mounted in Windows via mapped network drive so I access it like any other DAS except it's through 1GbE and when I'm away I can just pull it up in a browser or on my phone. It can do a ton of other shit but I really only use it for file sharing and I also host a Mumble server on it for my friends.
