1) Get some strong fans (e.g. ULTRA KAZE DFS123812H-3000 is strong)
2) Consider watercooling (expensive though).
3) cudaHashcat offers -w 1, -w 3 etc. options but i guess this won't help much.
4) Reduce clock speed. Have a look at these:
nvidia-smi -i 0 -ac 3505,1655
nvidia-settings -a GPUPowerMizerMode=1 -a GPUFanControlState=1 -a GPUTargetFanSpeed=100
nvidia-settings -a [gpu:0]/GPUPowerMizerMode=1 -a [gpu:0]/GPUFanControlState=1 -a [gpu:0]/GPUTargetFanSpeed=100 -a [gpu:0]/GPUGraphicsClockOffset[3]=-1000
n
For me, the most effective things were ULTRA KAZE and GPUGraphicsClockOffset ... Adjusting clockspeeds allows you to adjust power drain while hashcat is running, e.g. polling your solar panels controller and adjusting GPU power usage to the available power. works excellent.
