Dell :: Penryn Minimum Core Temperature

It seems like the temperature readings from both cores of my P8400 on my Dell Latitude E6500 running Windows 7 RC have some sort of minimum built into them. The reported temperatures will never drop below 32 for Core 0, and 39 for Core 1. Even after I resume from suspend, when the CPU should be at room temperature, as soon as I boot up it's 39/32. Similarly, while temperatures above that on SpeedFan show normal fluctuations, like you expect from a CPU temperature reading, once it hits the floor, it just becomes a flat straight line.

I'm not sure if this is the sensors, the software, or what.
