v0.73 is up now guys and it has fan control built in on a per card per coin basis. I am going to add more functionality around the fan control in the next version but for now I wanted to get this out for people like GaryH to at least have something they can use.
Gary for the record I don't know that I have any of my running COOLER than 65 C ...most are in the 70 - 80 range. 65 is crazy cool. You must live in a crypt! LOL
I run Nvidia's and from what I've read once they reach a certain temp they will throttle themselves back so I keep them fairly cool. The hottest card the MSI 1070 runs @ 53C whereas the Asus 1070 Strix's are @ 46C. Right now my rig is running in the basement, but once the winter temps hit it will be upstairs warming the living room/kitchen.
Since I don't believe I can upload pictures yet, I made a video using a Gopro but didn't realize the lighting was as bad as it was. It shows the 640x480 resolution and also the same sudo error. Should of edited more of the dead space out but wanted to get the video posted tonight.
