That's good to know - if you've managed to get any daytime images with it, I'd love to see how it goes.

That's pretty hot. The fan can only circulate the air that it has, so although that's better than no fan, if I do it, I might try to put some filtered holes underneath with very fine mesh, just to give it a chance to get some cooler air.

I think the issue was with the older USB 2 model, not the newer USB 3 one, but I will stand corrected. I have both kinds of PI here. I suspect the older one would do just fine anyway, it's not that "busy".
