Default Nvidia cards and thermal management?

Hi,

Do any Nvidia cards (especially the GeForce series) have on-die thermal
sensor diodes for core temperature measurement? I have had two cards fail
because of faulty fans. Seeing how the GPU cooler fans, by default, don't
incorporate any kind of RPM monitoring (and removing heatsink and/or fan in
most cases voids warranty), I was wondering if Nvidia has any provisions for
on-die thermal monitoring and management of the GPU? I don't think AGP port
incorporates separate pins to accomodate this feature in a way that Intel's
Slot1 does, so any such monitoring would be left to the graphics card
driver.

Any information would be greatly appreciated.

Regards,

Tonci

Is that it? I would hope that all current and future cards incorporate
this feature. It gives great piece of mind to know that if the fan fails,
the hardware will not fry itself.

So does the 5900. In fact temp monitorin goes on constantly and the fan speed
increases or decreases according to temp.

The 6800GT does.
