Antminer s5 board problems after reaching 80C

[Miramanee]

So my antminer s5's briefly reach 80-81 degrees C when I had left them for a while without enough airflow, but they were both set to shut off at 80.  Now on one of them, only one board will hash properly and the other has 4 o's and a lot of x's and dashes. It's drawing about 345 W from the wall and I know the power supply isn't an issue.

The other one has the same PSU connected but won't draw more than ~35W and won't mine.

Do you think this is because they reached high temperatures?  If so how would I go about getting them repaired? Other suggestions?

Thanks!!

Hitting 80C is not a good thing.    Could it be?   Possibly it's hard to say without more info.

What is the PSU you are using?  Have you tried a different one to see if it makes any difference? (They should not be hitting 80c either).

My standard S5 suggestion is :

First I would look at this and check connections - https://bitmain.zendesk.com/hc/en-us/articles/204875015-How-to-diagnose-S5-hashing-PCB

If that does not work then look at software - https://bitmain.zendesk.com/hc/en-us/articles/203559969-My-S5-hashes-at-about-600GH-S

But with the extreme heat check for damage before trying anything.
