1) to force 100% fanspeed, try this before running hashcat:
nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=100"
nvidia-settings -a "[gpu:1]/GPUFanControlState=1" -a "[fan:1]/GPUTargetFanSpeed=100"

2) for restoring "auto" fanspeed mode:
nvidia-settings -a "[gpu:0]/GPUFanControlState=0"
nvidia-settings -a "[gpu:1]/GPUFanControlState=0"


If it doesn't work you might need to adjust the coolbits flags in /etc/X11/xorg.conf or use this command to create a new one:

nvidia-xconfig -s -a --allow-empty-initial-configuration \
--cool-bits=12 --registry-dwords="PerfLevelSrc=0x2222" \
--no-sli --connected-monitor="DFP-0" -o /etc/X11/xorg.conf

sed -i '/Driver/a Option "Interactive" "False"' /etc/X11/xorg.conf


Overview coolbits: (please google a bit to find out more - you really want to be knowing what you are doing here, especially i wouldn't touch 8 and 16 on a rented system)

4 … (thermal monitor page will allow configuration of GPU fan speed) <--- this is what you actually need
+
8 … (allows setting per-clock domain and per-performance level offsets to apply to clock values) ***CAUTION***
+
16 … (the nvidia-settings command line interface allows setting GPU overvoltage) ***CAUTION***
=
28 … (potentially fried gpu)…



p.s. please kindly send me a private message, i'd be interested where you can rent a system with 2x1080 ...
