MacFan 0.5 has been released! Temperature monitoring is now available in MacFan and should be working on all systems. As usual, let me know if you encounter any problems using it and I will investigate ASAP.

Release notes are included below and summarized here.

Fans are now identified by name as well as number.

Basic version of temperature monitoring now implemented:

Run MacFan with the /temperature or /temperatures option to display current temperatures of all active sensors. You can also run MacFan with a number after the /temperature option. This causes the temperature display to run indefinitely and refresh every x seconds. For example, MacFan /temperatures 20 causes temperatures to be refreshed every 20 seconds. At the moment, temperatures take a long amount of time to read ( can be as much as 15 seconds on machines with many sensors ). I am focusing on speeding up this process for the next release.

Unfortunately, applications closed by MacFan are not reopened upon exit when running MacFan in temperature monitoring mode with a refresh interval specified. This is also on track to be fixed in the next release.

RELEASE NOTES


USE OF THIS PROGRAM IS AT YOUR OWN RISK. I AM NOT RESPONSIBLE FOR ANY DAMAGE CAUSED TO YOUR COMPUTER THROUGH THE USE OF THIS TOOL. AS STATED ABOVE, THIS PROGRAM IS DISTRIBUTED WITHOUT ANY WARRANTY.


Usage:


Start an administrator command prompt and navigate to the directory you extracted MacFan.exe to. Run MacFan like this:

MacFan.exe <Desired RPM for Fan 1> <Desired RPM for Fan 2 (if applicable)>

<Desired RPM for Fan 3 (if applicable)> <Desired RPM for Fan 4 (if applicable)>

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.

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. For example, to set both fans in a MacBook Pro to 3000 rpm you would type:

MacFan.exe 3000 3000

For MacPro users, control of the Power Supply Fan is currently not working. Make sure you always pass 0 as the fourth argument in order to not attempt to control the power supply fan. Passing anything except 0 as the speed for your 4th fan could result in damage to your computer. 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. Example of running MacFan on a MacPro:

MacFan.exe 1500 900 2000 0

MacFan does not override Apple's built in temperature controls but simply raises the minimum speeds your fans can spin at.

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.

In order to monitor temperatures, run MacFan with the /temperature or /temperatures option. You can optionally specify a number after the temperature option ( example: MacFan /temperature 20 ) in order to refresh the display of temperatures every x seconds ( in this case, 20 seconds ).

At the moment, temperatures take a long amount of time to read ( can be as much as 15 seconds on machines with many sensors ). I am focusing on speeding up this process for the next release.


Upcoming Features:


Working MacPro PSU fan control.

I am also working on allowing the user to create rules that will govern automatic temperature control.


Change Log:


MacFan 0.1:

Initial release. Supports all non-iMac Intel Macs for manual speed control of each individual fan through command prompt.

MacFan 0.2:

Supports every Intel Mac. MacFan reads fan information directly from the SMC for any computer not found in its internal database. Full functionality is provided and to guard against incorrect SMC minimum fan speed values as a result of using SMC Fan Control in Mac OS X and rebooting, not shutting down before booting Windows, a warning is displayed if the values seem too high for your computer.

MacFan will now automatically terminate BootCamp.exe, KbdMgr.exe, and everest.exe on startup and restart them upon exit.

MacFan 0.25:

Fixes minor bug that displayed a BootCamp.exe stopped working dialog on Vista when BootCamp 3.0 drivers were installed.

Shortens folder name to make it less of a hassle to run.

MacFan 0.3:

Fixes issue on MacBook Air and regular MacBook that could warn you that the SMC minimum values seem too high for your computer when they are default.

Fixes internal database issue preventing detection of MacPro.

Cleans up code for easier transition from ini file to registry in a future version.

Adds 64 bit version to fix issue with closing 64 bit processes (KbdMgr.exe and Bootcamp.exe) on 64 bit systems.

MacFan 0.4:

Fixes issue on some machines that could cause DEP to close Bootcamp.exe when attempting to terminate it. Unfortunately, this workaround results in a duplicate bootcamp icon in your system tray until you mouse over it. Once you do so, it disappears.

Fixes issue causing BootCamp.exe to not be properly reopened after MacFan closed it.

MacFan 0.45:

Fixes an issue where, if computer MacFan is being run on could not be found in database, minimum and maximum values would not be recorded to ini file and program would not be able to set fan speeds correctly.

MacFan will now work as intended on machines not found in its database.

MacFan 0.5:

Fans are now identified by name as well as number.

Run MacFan with the /temperature or /temperatures option to display current temperatures of all active sensors. You can also run MacFan with a number after the /temperature option.
