If the 1090T's anything like the 1055T that I own, here's what you're wanting to hear.
I've known about this 'problem' since I first bought my 1055T; the temperatures were inaccurate in the OS, but read properly in the BIOS. I've since overcome the issue by reading what I believe is either the correct temperature, or the motherboard socket temperature, which from what I have read is only a minuscule 2-3c off the core temperatures at most times.
After watching the temperatures for a while, I've decided it's just like most of the other 1055T's out there, and reports temperatures ~10c lower than what it actually is.
Anyway, about the cooling issue, my 125W 1055T idled at 35-40c on the stock cooler, and loaded at around 50c. With my Corsair H70, even pumping 1.475v through it only makes it idle at 30c and load at 45-47c, which is very acceptable.
EDIT: accidentally clicked post, so as I was saying..
I don't see why you people are saying 'avoid 62c' at all costs. It is not the shut off point, because the silicon and other materials can withstand temperatures in excess of 62c. This temperature is more of a temperature at which you should avoid holding it at or exceeding for long periods of time. What I'm trying to say is, if you tick over to 63c, your Phenom won't cause Chernobyl II
