..The maker web site has some general ideas on how to set the application..

I've used free version & it works OK in my Mac OS X systems; aren't newest.


• Macs Fan Control - control fans on Apple computers, also Windows via BootCamp:

https://www.crystalidea.com/macs-fan-control


You can choose which sensor to rely on for the application to work, or choose

the Automatic mode. I set the sensor to one closer to a source of heat (CPU or

GPU, depending on what the Mac is used for) and then choose Auto.


• Macs Fan Control - Help & Support:

https://www.crystalidea.com/macs-fan-control/support


I can switch from one setting to the other; faster fans to cool quicker after heat

build-up, then later Automatic for general use. ~ You can choose. Learn how

the hardware works, where sensors are, and how the mac is affected by heat.


• Supported Temperature Sensors - Mac Fan Control:

https://www.crystalidea.com/macs-fan-control/temperature-sensors


To have the menu bar info appear is very helpful; easy access to toggle the app.

I seldom change the sensor locations for Mac Fan Control. But after some resets

these settings will go back to a default, and leave my custom settings behind.

The automatic default temps are usually best, unless you've gotten some additional software load

or insufficient hardware (RAM memory, HDD free space for temp swap Virtual memory, etc) and or

several other factors that you may or may not (yet) have found by experience.


The best cost effective third party fan control is the free version of Mac Fan Control. You could try

and enter command-line or other Terminal commands to try and figure the same control; and have

something that isn't quite as useful nor practical across the range of temperatures & sensors.


IF you have upgraded HDD (or SSD) HD the original sensor for fan not longer works, the reason

would be evident; there may be a circuit/special cable to help fan controls so the fans won't race.

See the OWC site for their cable set, if that's why you're looking for better fan controls.


Good luck on your search; actual practical use of the Mac Fan Control (change its settings, use info

from the software maker to determine what else you could do, etc) ~ or contact application's maker.


Because I've used the product and have owned/used dozens of different Apple/Mac computers,

and have no cares if you choose to use the product or not (and get nothing from trying to help

people here for free, as uncompensated volunteer without any subsidy) I wish you well. I'm done.

Hi K. Shaffer - Thanks for your reply, but no info on best operating iMac 2010 Fahrenheit temperatures.If possible, would rather set the fan RPM's once & not change again.Apple Support contact had no info either. I will check with the computer repair shop. My current RPM fan setting's are - ODD-constant value 3050 - HDD -constant value 4507 - CPU -constant value-2400

Hey cataholic,


I'm running mine (also on a mid-2010 iMac - 27") at:


ODD - 2200 constant

HDD - 2225 constant

CPU - 1900 constant


Temps are on:


Idle - 46°

Light load - 53-56°

Heavy load - 60-65°


(all C)


That way its staying reasonably quiet but also cool. I won't say it's optimal but it's not sounding like a jet turbine either, so I'm good with it.
