One chain with higher temp on a Antminer s9

Hi everyone!
Just recently noticed that one of the chain in my Antminer S9, is showing higher temps than the others, also more HW problems, in fact I can’t select Overclocking profiles above 870w.

Is that hash board going to die? or I can do something to fix it?
Also is is possible to deactivate that chain from HiveOS in the farmdash board?
