A Python3 script to auto-control NVIDIA GPU fans during password cracking
Requires Python daemon module (apt install pythyon3-daemon)
usage: fancat.py [-h] [--debug] [-t [40-90]] [--daemon] [-m [30-100]]
Auto-Fan control for Hashcat with NVIDIA
optional arguments:
-h, --help show this help message and exit
--debug Enable debug messages
-t [40-90], --target-temp [40-90]
Target temperature (celcius) to maintain GPU. Defaults to 80.
--daemon Daemonize this process. Default is False
-m [30-100], --min-fan-speed [30-100]
Minimum fan speed allowed (30-100). Defaults to 40.
Running with default settings:
$ ./fancat.py --debug
Enabling fan control: True
