NvAPI_GPU_GetThermalSettings() -1 NVAPI_ERROR

[cudahashcat]

Hi,

Please could you help me with the following.

My setup:

Card: NVIDIA GTX 970M
Drivers (latest): 368.81
OS: Windows 10 64bit
Hashcat: cudaHashcat-2.01

Attempting to crack Cisco passwords using the following command:

cudaHashcat64.exe -m 2400 hashes.txt

CudaHaschat runs shortly, recovers one hash before repeatedly displaying the following error:

NvAPI_GPU_GetThermalSettings() -1 NVAPI_ERROR

After doing this a few times, the machine crashes and shutsdown.

Any suggestion is appreciated.
