Which switch would be best in an enclosed small box?

I have an application where I will be putting a switch in a small enclosed box.
Will the new WS-8-250-DC
be OK, or should I be concerned with the fan and heat and go with the mini?
It's a plastic shelled box that will be mounted inside a barn.
@Chris - curious on your thoughts on this.

Maybe Dave could chime in since he had a big part in the design. AFAIK the MINI has additional robustness built into it to tolerate the heat. I know they used through-hole polyfuses so that they air cool better. I asked but never got an answer if they did the same on any of the others.

I'd go with the 6-mini pal. I've got a couple spots with the small enclosure Chris sells and my switch's board temps never exceed 80C, even when it's 108ยบ outside in direct sunlight. My 12DC I just installed today drawing just over 30W (figuring 88% efficiency) is in a larger battery enclosure with multiple vents and is sitting at 51C board temp, PSU temps are 33C, PSU Controller is 57C and fan is at 6750RPM.

12 port mini & 6 port mini will work in same environment, both use the through-hole fuses.
