ocl v1.36 / WARN: ADL_Overdrive6_FanSpeed_Get(): -5

Hello,

Fresh install of Windwos 8.1, Catalyst 14.9, on Radeon R9 290

Running oclhashcat 1.36, benchmark mode :

and

Seems like it can't get the temperature and the fan speed
However a tool like GPU-Z can see the fan speed, but not the temperature (0.0°C).

Can I conclude that the temp sensor of my card is dead ?
What about the fan speed sensor, it seems to work, is it an oclhashcat issue ?

Thank you.
