Whats up with fans starting to spin 100 % without a reason with these XMR miners for random cards with random interval? Same problem with Wolf0s miner. I'm using afterburner for fan control and none of the miner settings. When the fan speed goes crazy it overrides any afterburner control over them and I have to restart the rig to reset the fan speeds.
do DDU and use 16.11.4 driver. it will fix the accidental 100% fan issue. was having a lot of those last year on other driver versions.
Also you may try sgminer forks for better cryptonote results
