Did you make sure all the ribbon cables are connected tightly?
Yeah ribbon cables are good.
I'm thinking I might try reversing the thing tonight, i.e. power the system board from the other blade, and shift the fan to the other side and see what happens.
Can't think of anything else. I guess maybe try and flash the firmware?, factory reset didn't do anything though...
Just an update, it's started hashing now but it's fan is still on max, 4200 constant and a constant 35 Celsius, ha.
Would be nice to get the fan to shutup a bit.
Has anyone else had a fan that's constantly maxed out? (non overclocked)
