Why does the fan speed stay at 26% when my GPU reaches 101°C?

At the default 26% fan speed, some intensive OpenCL applications can make my Radeon HD6970 reach 100°C or more. I'm running Debian GNU/Linux with fglrx 11.12 drivers, and if I don't set the fan speed manually[1], the GPU would probably burn up. Is there a way to enable some kind of automatic fan speed control? What is the safe temperature for the Radeon HD6970?

1. Something like: aticonfig --pplib-cmd "set fanspeed 0 50"
