Great idea for what?

It's basically the same idea that Intel had with the P4, implemented at board level instead of being built into the proc itself. It allows your machine to still run at a reduced level of performance instead of a blanket shutdown due to high heat. I'm sure you know of many situations where a reduced level of performance would be much preferable to a blanket hard shut down, which will also happen on nforce2 boards if the temp continues to rise above shutdown threshold.

they also have that option on the Epoxd 8Rda+, so i think it might be a feature on the Nforce2 chipset.

I don't know about that, but it seems to be a good possibility because I think that this feature is on all the nforce2 boards.
