i'n not sure it was the bios or other components..
and i don't know at which temp..
we all know that guy with fluorent (and liquid nitrogen)
and components on his mobo broke when he cooled the mobo.. (it could be the condensators or the bios or etc)
but i dont know the link and temps..
and these supercomps are build for these circumstances..
but no probs when u stay above the -50C..
well it could not be the bios
