I need some knowledgeable advice.
I have an external dual-drive enclosure (2 x 8TB drives running RAID 1) and the fan has died. The manufacturer sent me a replacement, which didn't work, and a second one, which didn't work. They refunded me and that's that (they didn't like my suggestion of me sending it back and getting a new one), but I got to keep the case (they have relisted the exact same case, but at an almost 50% increase in price, weird).
I've been looking for replacement fans, but in the meantime, I'd like to run the enclosure without its cover on (which is aluminium, no perforations). The two drives are very close together (stacked one on top of the other), so I'd like to max potential convection cooling by running it on its side (so the drives are vertical).
Any drawbacks to this I should be aware of? I'm even thinking of not getting a replacement fan (it's only 55mm in diameter, pretty small) and leaving the drives exposed permanently. Bad/good idea? I'm in a typical office environment, but with no AC (it can get a little warm in here in the summer, but not too bad).
Thanks very much for any insights.
