I've seen 90º+ for the CPU A too, before it shut itself down.
What temps are people seeing on MacBooks for the 'Heatsink B', because mine is regularly seeing a ridiculous(at least it seems to be) 120º!
On a related note, how hot does your charger get? Mine seems way too hot at times.*
*On another related note: I would advise members note to fall asleep and roll over onto their charger. I did and woke with a burn on my back, the blister was about 3cm across and 8mm raised. Ouch!
