I didn't find anything as detailed about IDTAMB0480 though, all I could find was this: http://www.idt.com/products/files/6186383/AMB0480_product_brief.pdf Astonishingly, at least to me, the max temperature for these things seems to be 124C: see page 12 of the above link or section 3.3.1 at page 25 of http://download.intel.com/design/chipsets/designex/31306603.pdf Do I really understand this correctly? Or should it be divided by 2? I'll read Intel datasheets a bit more tonight, I'm sure they're ideal bed-side reading ;-) Regards, VZ
