Why not get randomness from sensors?

There are some untapped sources of entropy: the hardware sensors on most motherboards. The temperature, voltage, fan speed, etc. sensors could be manipulated by someone with physical access, but only to a limited precision. Doing some kind of differential sampling and not counting zero inputs as having any entropy should help.
Is there a reason the drivers for those devices don't contribute to the entropy pool?
