So, I have two hash boards hooked up. I figured out it doesn't work if you don't have one hash board in the middle. The problem I'm having now is, there is no fan control. Every number I put in the GUI doesn't do anything. I thought I would try and find a manual fan controller, but I've had no luck. Any ideas? I'm thinking the middle hash board that croaked was maybe a special hash board that was able to control the fan?
Thanks for the tip on DeoxIT!
The fan is probably powered by the middle hashboard. Unscrew it, take the hash boards out and reconnect the fan to the first hash board. Leave the middle hash board out if it's had it and that should solve your problem.
