How can I find readings (and adjust) the fan speed of my late 2012 27inch 
fusion drive iMac?  Is there data log of fan history?

Mac failed yesterday and today. Restarted OK after say 20 minutes after trying 
different power point, cable, etc.  Mac case was cool to touch but I don't 
recall any fan sound at all.
