get a motherboard with no fans honestly though it should be setup in the BIOS and you shouldn't need to change a thing in the OS (I never have).
 I've not the foggiest and I've never encountered such a description or issue before. You have to go a fair way wrong to fry a mobo via temperature. Get a decent case with fans and you should generally be ok. (assuming you're not overclocking).
I wouldn't attempt reversing fans either imho (cases etc are usually designed to suck and push air in a single direction).
 that's everyone's nightmare just double check the little indicator and you'll likely be fine.
