Fan Control Apps for MacPro 2.93 Mhz ....

Question

Ok, I figured out how to disable Fan Control.
Now I only have smcFanControl installed. I can hear the fans running all the time now. Before I installed FanControl and smcFanControl I could rarely ever hear the fans, even during the hot summer.
I have the slider controls set to the minimum, but the fans still run constantly, and my room is in the 50s F.
I really don't think the fans should be running all the time. The only way I can find to stop this, is to delete smcFanControl.
Is there any other FanControl apps that will allow you to adjust the fan speeds so the fans will not run all the time?

Answer 1

the fans are suppose to and need to run.... all the time.
but normal default is 499/599 rpm
boosting the minimum default is useful
you can have and should have profiles for low-medium-high if you push and use your system heavily
sounds like you have
too many cooks - spoils the soup
corrupt preference file
are not using the SmcFanControl for intended purpose and as designed
most people do create multiple sets and have "my default' (for want of a name) @ 800-900 which improves air flow and thermal temps while still being quiet.
older FBDIMMs are HOT and helps keep them in the 60's *C or if you have a hot GPU and need more air flow
maybe you have dust or other issues or the Mac  Pro is recycling its own hot exhaust
The thing to look at is WHAT is (hardware) Monitor showing for your TEMPS from the thermal sensors as to what is or is not normal
And reset the SMC / and delete the plist files used
Never use more than one background utilty for a job and keep all of such utilities to a MINIMUM for best fastest stable and for performance, they do add up, they do matter. "Less is more."
