@allcoinminer, No haven't gone that far. While trying the different controller cables and power I did feel the heatsink and no matter what I tried the right hand blade did not get warm.

Right hand side with the ethernet port facing you.

Problem
Took delivery of 2 x S3 miners from batch 2. Out of the box one works fine the other only shows chain 1 as working.



Things I've tried

• Tried 5 different CX750 power supplies
• Updated to latest firmware (Bitmain support said do this)
• Removed and refitted cables from controller to blades
• Swapped the 2 cables from controller to blades round
• Used combinations of all 4 6 pin power sockets, 2 front, 2 rear and other combinations

Nothing I have tried has worked. Bitmain suggested the firmware update and I've had no other replies from them

Not sure how removing the heatsinks and replacing the paste is going to help?

Any help appreciated
