I actually have a couple of those really small fridges that I could use. I have one in the house that I store seeds in. The problem is space. The little out building is pretty full. There is no shelf space and very little floor space. I'm just not sure where I could put it since it requires some room for the coils to shed their heat. I'll have to check into it more. > > I have the fans set to spin up faster at 35c and above. Without the > fans they sit around 45c on a typical day and use.

When I put the drives in the outbuilding, they won't be powered up or anything. They can handle more when powered off than they can when powered up and in use. While I still want to avoid heat, that real world info does help a lot. If I recall correctly, we have similar weather as well. I don't live close to the ocean but when the winds come from the south, the moisture gets here soon enough. I live about 250 miles from the gulf coast. For weather tho, it doesn't take long for heat or moisture to go that far. The biggest thing, the salt part is gone by the time it gets here. ;-) One thing about the enclosure I got, it has a fan on it. It moves a fair amount of air. Drives don't use much power so it doesn't take a whole lot of air flow to get the job done. Here is a link to one like I have. https://www.ebay.com/itm/132706512662 One reason I got it, someone else using Linux said it worked for them. Since I only use Linux, good deal. Thanks. Dale :-) :-)
