I have noticed that fan speed on my Mac is 499 rpm. Now this is a computer with installed OSX El Capitan, Xcode 8.2.1... I have noticed this when Xcode got crashed few weeks ago (the information was provided in Xcode crash log). Now, today, when it crashed again, I have noticed the same fan speed, which is 499...That is a bit odd I must say, because rpm are very low, and I got same number twice.
I wonder is this accurate info actually and what is the normal fan speed for MacPro3,1?
