I know the S17 Series have heatsink issue and was sharing my experience and personal opinion as honestly as I could.
And YES I did have additional heat sink issues down the road when using other firmware.
I was not attempting to overclock either, I was trying to underclock and improve efficiency and I may not have fully understood how to adjust Braiins after initial install to underclock.

I do look forward to trying Braiin on the S19 in the future I hope as I had been a slushpool miner for several years.
I may be wrong in assuming that it was Braiins, but it was odd after over a year of trouble free use before trying, and certainly did involve the poor quality S17's Bitmain produced.
