#Smc fan control not working manual#
Supports all non-iMac Intel Macs for manual speed control of each individual fan through command prompt. I am also working on allowing the user to create rules that will govern automatic temperature control. I am focusing on speeding up this process for the next release. You can optionally specify a number after the temperature option ( example: MacFan /t 20 ) in order to refresh the display of temperatures every x seconds ( in this case, 20 seconds ).Īt the moment, temperatures take a long amount of time to read ( can be as much as 15 seconds on machines with many sensors ). In order to monitor temperatures, run MacFan with the /t or /temp or /temperature option.

If your machine gets hot enough that Apple's built in temperature controls want to raise your fan speeds, they should still raise them to the same speed they would be at otherwise. MacFan does not override Apple's built in temperature controls but simply raises the minimum speeds your fans can spin at.

Proper control of the power supply fan or removal of the 4th argument if it is not possible will be included in the next release. Passing anything except 0 as the speed for your 4th fan could result in damage to your computer. Make sure you always pass 0 as the fourth argument in order to not attempt to control the power supply fan.

For example, to set both fans in a MacBook Pro to 3000 rpm you would type:įor MacPro users, control of the Power Supply Fan is currently not working. Of course, if you already know the acceptable ranges for your fans you can go ahead and run the program right away with the speeds you desire. Run the program once with no arguments if you need to know how many fans are in your machine and the minimum and maximum speeds those fans can be set to.

Previously, the first value would not be displayed until after the last value was gathered, which could result in information as much as 15 seconds out of date on a MacPro. Temperature sensors are now refreshed as soon as the information is available. If they are invalid ( return a negative value, a 0 value or a value above 129 degrees celsius ), marks them as invalid in the registry and rereads keys from registry. Now double checks temperature sensors that are displayed when keys are being read from the registry.

Temperature monitor now also monitors current fan speeds.įixes issue where a message would not be display if refresh was delayed.įixes issue where the system could lock up for a few seconds after quitting temperature monitoring and resuming an application that accesses the SMC. Note: restarting does not reset your fans to default speeds.
#Smc fan control not working upgrade#
In order to upgrade from an earlier version of MacFan that uses an ini file, make sure your fans are spinning at default speeds by putting your computer to sleep or shutting it down before you run the new version of MacFan. All data stored there is now stored in the registry. MacFan 0.65 has been released! Release notes are included below and the changes are summarized here for your convenience:
