Those two tickets are related to Overdrive profiles and the --gpu-temp-retain switch, as oclHashcat attempts to restore the default profile upon exit. #439 is specifically related to Overdrive6 cards, and you have an Overdrive5 card.
How exactly are you attempting to set the fan speed? Are you using the --gpu-temp-retain switch?

It takes some time to work because you are essentially relying on your GPU BIOS to control the fan, which is programmed for gaming workloads, not compute workloads.
