with Mac i5 2012 and Catalina 10.5.7 with neural mix the fan have max speed.....

mmmm I think thet the latest version 3.2 with old Mac and Catalina is no good the fan system is very high

and the stems sometimes glitch

yeah, mine is acting up as well…never thought it might be an overheat issue.
seems to be time to update hardware, then…apple refurb store, here I come!
