< 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.

Há um gráfico interessante no link que mostra 10 anos a 108 ° C declinando para 1 ano a 148 ° C
Os fabricantes citam uma temperatura máxima, por exemplo, 105 ° C para a GeForce 8800
