Since 2015 and in that time I have learnt an awful lot from this site
I think my digital temperature fan controller has failed and in the course of isolating it I think I may have got the + and - crossed on the Arctic fans.
They now don't work at all.
Are they sensitive to polarity ?
At worst I thought they'd just spin the other way.
Looks like two new fans needed as well.

My ex pc fans will not work with reversed polarity. On reconnecting with correct polarity all was well.

My experience is pc fans connected the wrong way round will die. Some may be protected by diodes but not all are
