"That's not cooling!" you say, and you are right. But Kyle actually performed a pretty clever test to check whether the Soltek motherboard was using the internal diode for CPU temps:
"Soltek does include a hardware monitor software package. While this excited us in being able to use the on-die diode to read the core temp, we were disappointed to find out that the software did not use the on-die diode but rather a temperature sensor located in the bottom of the Socket A like we are used to seeing. This can be easily confirmed by using a canned air canister turned upside down and spraying the bottom of the Socket A with liquid Tetrafluoroethane that immediately freezes the bottom of the Socket A. You will immediately see the temperature drop in the Smartguardian software. If it did in fact use the on-die diode, you would not see an immediate response. We did verify this and Soltek confirmed our theories."

I hope to see tests like this for ALL motherboards (8K3A is the subject of some debate)
