AMD Overdrive Thermal Margin Reliability

[Aneuthanasia]

Hi guys,
During stress tests I use HWMonitor and AMD Overdrive to monitor the temperature of my x6 1075t. I understand that the 1075t should be taken up to around 55-62 degrees Celsius as a maximum.
My concern is that when HWMonitor indicates a temperature of 50 degrees in any core, overdrive shows a thermal margin of 20 degrees. This suggests that overdrive thinks it's okay to ramp up the temperature to 70 degrees?
Anybody able to shed some light on this?
Cheers,
A.

HWMonitor has never been any good with AMD platform.
