I'd second that slim and Aarons, set it to 92 and give it some time the first adjustment you might want to wait a bit more time than 30 min as it takes time to warm the mass of the rack but after that first adjustment 30 min is fine. Are there snakes in it or is it empty?

If it is empty and you have time I like to find the unregulated max temp so I just plug it in the wall for an hour or so (don't leave stick around) and measure the temp. It will tell you how badly you need a fail safe. I have enclosures that max out at 100 and ones that max at 190º at 100 a failsafe is a question mark at 190 a necessity.

Room temps are part of the rack temp control, typically they are set to 80º to hold the ambient and cool end temp.
