There are plenty of questions about what a safe gpu temperature is, but these seem focused on what temperatures a gpu will survive at in the short term, regardless of whether it may shorten the cards life.

I recently ordered a video card that I need to be able to run under constant strain at work, but its longevity is very important. I would not have intentionally overclocked it, but to my surprise, it was the "overclocked" edition (Sapphire Radeon HD 5770) that arrived in the mail (doh!).

What temperature should I try to keep a GPU to, if I not only want it to survive today, but want it to live a long healthy life?

P.S. We will probably be buying other cards, and any other longevity suggestions are welcome, but my actual question is specifically about temperature.

<105°C

Junction temperature TJ usually is limited to +150°C for silicon ICs. Devices may operate momentarily at slightly higher temperatures, but device life expectancy decreases exponentially for extended hightemperature operation. Usually, the lower the junction operating temperature, the greater the anticipated life of the IC.

There's a nice chart at http://www.interfacebus.com/Integrated-Circuit_Derating_Guide.html which shows 10 years at 108°C declining to 1 year at 148°C

The manufacturers quote a maximum temperature, for example 105°C for the GeForce 8800
