   That's reasonably accurate.   
      
   Now you know why I extracted the controller PCB and   
   just use one of those "loose" on the table. I have some   
   wooden blocks with rubber covering over them, as   
   a surface to lay the hard drive on.   
      
   The enclosure on that one, had no fan, and there wasn't   
   any convection cooling scheme either.   
      
   I like to see a fan on an enclosure. There should   
   also be an intake and exhaust vent, so the fan can   
   actually blow air through. I had one enclosure, I had   
   to drill holes in it, so the fan could actually work   
   to cool the thing. The fan was blowing into a closed box,   
   which does not encourage cooling particularly.   
      
   On one enclosure, the fan used a sleeve bearing. The unit   
   was received "with a pool of oil sitting in the bottom of the case".   
   The fan lasted a matter of seconds, as the sleeve was so loose,   
   the fan could not rotate without "rattling". In other words,   
   the fan was already dead. And I replaced it with one from   
   my stock of 40mm (ball bearing) fans.   
      
   The adapter should be 12V, because the 12V rail is   
   used directly by the drive. The 5V rail (generated   
   by the enclosure controller board), could still fail, and if   
   the voltage were to rise sufficiently above 5V, it could   
   fry the controller on the hard drive. At one time, the   
   wall adapter had a four pin connector, with GND GND +5 +12   
   on it, and that is how the hard drive was powered. But   
   they decided to simplify the wall adapter, make it   
   output only one rail, and generate the +5V locally   
   on the enclosure controller PCB.   
      
   Part of the problem with advertising listings now,   
   is the pictures are poor, and a lot of useful info   
   is non-existent.   
      
   The last decent enclosure ("had a fan"), it still had   
   one shortcoming. The drive was held against the   
   connector, by a "chunk of stuff" that sat between the   
   opposite end of the drive, and the housing. And   
   that did not fit snugly.   
      
   What you're looking for then, is "ingredients".   
   Having a fan is good. Having a fan with sufficient   
   clearance so the air can actually blow somewhere,   
   that's good. Having holes in the case so the air   
   can escape, that's good. Having a mechanism to   
   hold the drive securely, and shock mounted, that   
   would be very nice if they could manage it.   
      
   If all the enclosures had a youtube video with   
   the enclosure open, you could see more of the details   
   and so on. This presenter is known for doing things   
   while too full of caffeine. He doesn't know the first   
   thing about what people expect from a video like this.   
   The chip on this could be an ASM1051, but because   
   we don't even have the model number of the unit to work   
   with, no further research is possible. But at least   
   you can see this one has no cooling to speak of.
