Hi Guys
Very new to mining and the other day I disconnected the power supply from one of my S9's and I noticed that one of the power pins on the hash board side is slightly singed and a brown color.
I blew it out with air and reconnected it and the machine appears to be hashing normally, only thing unusual about this particular machine is that both fans are always the same rpm.
Can you advise if this is a problem or dangerous or if it requires repair, I have attached a picture.

It probably wasn't making a good connection. Clean it real good and keep an eye on it. If you smell burning or the plastic gets hot you may need to get a different PSU if the connector is bad. As far as the Antminer goes you don't need all 6 pins connected for it to work. I only run 4 (2 positive and 2 negative).
