GeForce 3 and overheat protection

[PanzaMan]

Hi, does anybody know if the GeForce 3 chip has any sort of overheat protection like the GeForce 1 chip used to have????

I'll explain, it looked like the GeForce 1 had a system to slow down itself in case of it was overheat.

Well It happen to me that with my ASUS v8200 GF3 T200 I get a performance decrease when I overclock the card.

Is really appreciate any help
Thank you.
