IMac only seeing 1 FAN

[conceptsottawa]

I have a 27" 2010 IMAC running 10.11.2 . I can only get 1 fan showing not the HDD fan. Any ideas?

Here is a Pic of what I see. Anyone?

This iMac has only 1 fan, it's OK.

It has 3 Fans. Macbooks might have 1 fan. Imacs have 3. I have opened it to confirm. 3 Fans

IMACS have 3 fans, the program does not show this. So I am not sure what your getting at? Is the program only supposed to show 1 fan for IMACS?

There're more than 20 iMac models (iMac4,1, iMac6,1, .etc). Starting from model iMac13,1 every iMac has one single fan called Main. Before 13,1 there were 3 fans (called ODD, HDD, CPU)

Mine has 3 fans, so how does this help me? The program does not show me the 3 fans. Am I missing something?

Did you recently use Time Machine to restore this OS from one mac to another?

[conceptsottawa]

I think I did yes. I also tried to delete the program re-download and re-run

Can you run this bash commands?

Code: Select all

killall MacsFanControl
rm ~/Library/Preferences/com.crystalidea.macsfancontrol.plist
killall -u `id -u -n` cfprefsd

[conceptsottawa]

That did it. I now see all 3 fans. Thank You
