MacPro 5,1 Mid 2012 has fans blowing full blast on startup. SMC reset does not fix the issue. Is there any way of fixing this without going to the Genius Bar?
I’d run TG Pro to see if I could isolate the problem: https://www.tunabellysoftware.com/tgpro/ UPDATE compare mine that’s been running all day with yours
Please note yours is showing a hard drive sensor failure. I’d pull one drive at a time and restart to find the offending one. Your CPU’s are also running much hotter than mine.
