The fan is there to cool things down when the Mac runs a little warm. The fan isn’t easy to control, either, unless you have an app that monitors and controls the Mac’s fans. The app that does is free.
Kill Flash, Or Melt
There are a number of reasons why you’d want Macs Fan Control on your Mac. Again, most Macs just work, and when the fan comes on it’s a sign the Mac is trying to do the right thing.
When Safari or Firefox run the Flash plugin, the fans can startup and run awhile because Flash uses plenty of CPU and battery power.
However, there are other reasons to control the fan beyond Apple’s automatic on and off routine. Some Macs have replacement hard disk drives and Apple’s heat sensors don’t play nice-nice, hence the fan goes on forever.
Some MacBook Pro models had fans that wouldn’t stop running, either through a faulty sensor or a fan problem.
Macs Fan Control gives you monitoring and control over all the Mac’s fans. There’s even a Windows version to run when Windows is running on your Mac.
The app isn’t difficult to use but doesn’t look like most Mac apps. It displays the Mac’s fans, minimum RPM, current RPM settings, and maximum RPM. It also displays a list of the Mac’s temperature sensors.
If you think your Mac has a heat problem, Macs Fan Control is a good way to find out where.
You can even control each fan by using Automatic settings (the Mac controls the fan), or set a Constant RPM value, or a Sensor-based value with a temperature range setting.
Mac Fans Control is that useful utility you hope you never need to use, but you’re glad it’s free, and you’ll welcome the extra control options.
