External HDD Enclosures...HOT!!!
Jul 14, 2012

Hello everyone,

Recently I purchased a "Mediasonic HD6-su3s2 Aluminum 3.5" USB3.0 & eSATA External Enclosure" for around $40.00 US at NewEgg ( http://www.newegg.com/Product/Product.aspx?Item=N82E16817576015 ), and found that while connecting it to legacy or just older computer running USB 2.0, the transfer rates were very very slow. Much slower than if I were to use Ethernet 10Base.

Anyway, I did a few tweaks, and also tried running a HDD "removed" from the aluminum enclosure, and realized what I thought might happen, the drive got BLAZING HOT! I mean 118 F hot.

From what I have read up on, Standard SATA I/II/III Seagate, Western Digital, Maxtor, Samsung, and Hitachi HDDs should not reach 50c, and if they do, it can greatly reduce the life of the HDD. Anyway I tried using this enclosure with several of my "known Good" hard drives I have, and all drives connected within the enclosure whether: USB 2/3 or eSATA got blazing HOT over 118F after 35-40 min.

Now I realize that all enclosures can be designed and constructed differently, but does a HDD enclosure absolutely need a vent or fan inside it? Has anyone used this model here at the forum...( http://www.newegg.com/Product/Product.aspx?Item=N82E16817576015 )...? Could the problem be a cheap chip set used on the circuit board?

I realized later the drive was probable really laboring when I was running an image on that system running USB 2.0, and was probably at around 50C, but did not have a way to monitor it in DOS.

I came across another HDD enclosure, and seemed more practical, but expensive...


It does have a "warning monitor" built-in (red LED light), alerting the user that the 50 degree Celsius mark has been reached. Also, it has a 80mm fan for cooling.

It would seem to me that the enclosure with the fan would be a good replacement, but is it worth it for $69.00US? Any feedback on this would be really appreciated.

Thank you all,
