46C isn't near the limit of overheating IMHO. I didn't say all notebooks comes without active cooling for the HDD, i just said that mine doesn't, and i haven't noticed any overheating problems at all, not ever near. Has anyone here suffered drive problems and failure, due to a drive overheating in an enclosure? The question is-is there really a point in spending more for a more expensive enclosure, none of which (for 2.5 drives) have fans? Would it really make a difference? (Though I guess if you got caught in the rain with it, and it got wet, the mesh might not be such a good idea-letting water in)! It appears that it is partly steel mesh, for heat dissipation. I think it costs still more-I believe I saw it for $29-35 or so. Yet, one can buy others for $10-15.)Īlso, the following unit from Enermax, advertises that it has a special design for cooling the drive (again no fan though): (It usually sells for around $22-$25, not the $39 listed. What do people think? Would a little air space between the drive and ends of the enclosure case give better ventilation, better prevention against overheating? It costs more than the cheapest ones, although I don't know if it's worth it. The drive in that one is screwed to a board inside, so it would not move around inside the slightly larger casing. But that design would give a little space between the drive and the enclosure case. Still bus-powered, and still no room for a fan. I did see one SATA 2.5" enclosure that is slightly larger than others I've seen. They are all small, fit tightly over the drive (no room for a fan!), are bus-powered, etc. I have not seen 2.5 enclosures with a fan. Of course that requires external AC power.
Then I saw another discussion here that touched on external drive enclosures, and warned of the problems of drive overheating in aluminum enclosures (which they are all made of), and recommended enclosures with a fan. My reply was that-after you know whether to buy IDE or SATA, go for the lowest price, as they are all about the same, they all should work if you have the right type for your drive, with any OS, all seem to be USB 2.0, etc. Someone recently started a thread asking about these, which to buy.
