If you’re experiencing issues with fans, Resetting your SMC may fix the problem. For more permanent settings, please use fan sets.

Please note that manual fan speed slider settings are not saved across reboots. If the manual fan speed sliders are edited, those speeds will be used. Manual fan speed sliders #įan speeds can be set directly via the sliders in the Fans menu in the sensor menu bar item. The Default Fan Set popup button chooses which fan set will be used normally (when none of the automatic fan set rules are met). Trigger higher fan speeds faster than the system would, when there is high GPU usage.Trigger higher fan speeds faster than the system would, when there is high CPU usage.Have a higher idling fan speed when plugged into mains power.This means it is possible to do many things, including: Using automatic fan set rules, you can increase the speed of fans when certain events are triggered. In the example above, iStat Menus will use “My Fan Set” when any sensor is above 80✬. Edit the rule to suit what you are after.Click the + to the right side of the window.To create rules for automatic fan set switching: To use automatic fan set switching, choose Automatic from the Fans menu in the sensor menu bar item. That will let you create a set for normal operation, and also create fan sets to be used under different circumstances. IStat Menus can switch to a different fan set, based on rules you provide. To recall the set, choose it from the Fans menu in the sensor menu bar item. You can now edit the various fan speeds you’d like for this set. Open the iStat Menus app and go to the sensors tab.If you’d like to create a set of fan speeds that can be recalled at any time, this can be done with fan set. With the fan control set to System Controlled from the Sensor menu, iStat Menus will not control fans at all - your Mac’s fans will act as if iStat Menus is not installed. In addition, I wrote a pretty little application to monitor the CPU temperature.

As a continuation of my Dell fan control problem on my Inspiron 5100 notebook, I completely rewrote the IOI8KFan.kext driver and renamed it to simply I8kfan.kext.
#Os x fan control update#
IStat Menus can not control the fans on Apple Silicon Macs. Update (June 15, 2007): I8kfanGUI v0.2 with dual fan support has been released. Manual fan speed sliders in the Fan menu in the sensor menu bar item.There are four main modes of fan control in iStat Menus. iStat Menus can’t lower fans below the speed the System Management Controller (SMC) would normally use, but it can raise the fan speeds. This most recent version adds support for every current MacBook, MacBook Pro, MacBook Air, and Mini.Using Fans iStat Menus can help control the speed of fans in your Mac. As with any settings-tinkering software, you'll want to use smcFanControl judiciously-but fortunately this application always keeps fans in automatic mode (so speed will increase along with CPU load) and never lets you set the fan speed below the Apple-recommended minimum. SmcFanControl lets you monitor the current temperature (in Celsius or Fahrenheit), assign different minimum speeds for each fan using sliders, and even apply different settings when your power source changes (for example, going back to default fan speed when using battery power). This free, GPL-licensed utility has a single purpose: letting you increase the minimum speed of built-in fans, so your Intel computer will run cooler. If you've got burnt thighs from an old MacBook Pro or you notice that your computer is always overheating and crashing from using CPU-intensive apps (like playing PC games in a virtual Windows environment), you might want to check out smcFanControl. SmcFanControl lets the user set the minimum speed of the build-in fans.
