Working on a little Ethereum mining today.
~/claymore10/ethdcrminer64 -epool us2.ethermine.org:4444 -ewal <wallet>.<worker> -epsw x -mode 1 -tt 68 -allpools 1
I had been a sudo error
Failed to set new fan speed, check if miner has root access!
Which leave leaves the fans running at auto, while they are quiet, I really need to keep the GPU temperature lower than 89C which was getting way to high. Ideally I want to see it at around 66C. So what I diced to do was remove the -tt 68 argument on the above command which eilminates the error messages. Then to my miner.sh script I added these commands manually set the fan speeds for my RX 570 GPUs.
$ sudo echo 1 > /sys/class/drm/card2/device/hwmon/hwmon2/pwm1_enable
However I got an error permissions denied.
-bash: /sys/class/drm/card2/device/hwmon/hwmon2/pwm1_enable: Permission denied
After a couple of adjustments the command looks like this, it would work with sudo when running the miner.sh script as well as set fans to manual and then assign a speed.
So I used the follow commands
sudo /bin/su -c "echo 1 > /sys/class/drm/card0/device/hwmon/hwmon1/pwm1_enable" sudo /bin/su -c "echo 178 > /sys/class/drm/card0/device/hwmon/hwmon1/pwm1"
This will set the fan to manual, then set then fan speed. The speed is 0-255. So I want my fans to run at 70%, then I used 178 as the value. Now my fan speeds are increased and temperature dropped over -10C just by getting more air flow.
