What's the top temperature not to make the Chip 6600 burnt-out?

Probably want to keep it under 120 Celsius. I've run NV30 and NV35 GPUs to in the 120s C on multiple occasions during thermal experiments, with no noticable damage.

The NV3x series are rated for a 140C operating temperature. Even so, processor throttling in the drivers cut down GPU core clocks at 120C or so, so the GPU wasn't delivering full power at those temperatures. However, I noticed the 71.xx series drivers dropped the max temp from 140 to 120C on the control panel, so maybe the NV4x series have lower operating temperatures.

Yup, semi-conductor chips can handle temperatures up to 120-160C without being damaged permanently. It's pretty hard do damage nowadays' chips (CPUs or GPUs) even if it wasn't the case few years back, thanks to thermal throttling zones.
