Intel never documented the on chip digital thermal sensor (DTS) to be used for reporting idle temperatures and they've never documented these sensors to be used for reporting absolute core temperatures.

Using the DTS to report idle temperatures has always resulted in readings that are too low at idle. This has only become more obvious with the E8x00 series that uses very little wattage at idle and creates very little heat.

The new E8x00 chips still have a huge amount of temperature headroom when CoreTemp reports that they are running at 60C. At this point you are still 45C away from the Intel documented maximum safe operating temperature so what's there to worry about. Even at 4500 MHz and beyond I've yet to see a screen shot where anyone is even close to the throttling point.

This thread proves that Wolfdale is working great so Intel is not going to change anything. CoreTemp reads directly from the cpu so no bios update is going to change anything either. Everyone better get used to absolute temperature readings that don't have as much meaning as they used to.

Use CoreTemp and set it so it displays how far you are away from TjMax. That's the only fully Intel documented temperature information from these chips that you need to be aware of.
