No CPU fan speed shown, only an orange icon??

Thanks Steven. I appreciate I'm running very old software (OS X 10.6) but this specific iMac can not be updated to 10.7, so I'm also stuck with the legacy versio of MFC. I'm thinking that the fact the rpm of the CPU fan reports, say, 800 then zero indicats the fan isn't defunct. And I trust MFC is r...

No CPU fan speed shown, only an orange icon??

MacsFanControl.log - which I enabled via Preferences->Diagnostics

No CPU fan speed shown, only an orange icon??

Exactly the same symptoms here. CPU fan speed not showing in the control panel, just an orange marker. The log file is reporting the CPU fan running at around 1550 (min/max are 800/3600 respectively). Temperature is reported 42c-50c and I'm hearing an annoyingly loud fan at all times other than when...
