Small issue I noticed today.
Upgraded to Nvidia drivers 512.15 today to test out the new T-rex miner 0.25.13. Everything is running fine, but the GUI under "information" no longer shows the fan %. It just shows a static 0%. I am assuming this is a driver issue, as an older card I have on Gminer is also no longer reporting fan %.
Are T-Rex and Gminer also showing the fan speed as 0% in the mining console window?
In Awesome Miner, please select the miner and go to the System tab. Do you see all the GPU details listed here?
Please also let me know which nVidia GPU you are running and I can try to reproduce the issue.
