And the next error was the psu swapped it with a different one and all working fine

Thanks for the help

The new fans I bought was a 7200 rpm the ones in it was 6500 rpm so the draw on a 7200 will be slightly more then the 6500 so it was knocking fans out I have a t17+ that’s in bits so used the fans from that and it worked up to the next error which I’ve not had time to looks at

So after many hours yesterday we realised it’s the fan we was using it was too powerful causing a imbalance once we put fans on from a different rig it booted up but then when it was all back together it had another error

Already tested the cables so next step is the psu will update when I’ve tested

Thanks

Hi i have a S17e
it has been working fine for a few months then one day it said Fan lost ( fan 4 ) so i changed the fan, miner still wouldnt boot up kept saying fan 4 lost so i tried a diffrent fan still the same switched fan 3 and 4 and it still showed fan 4 lost so then got a new control board flashed it with the correct firmware and it still says fan 4 took a fan from another machine and to see if it was the fan i was using but it still said fan four
any help or guidance would be great thank you in advanced
