Friend of the blog Shane McFee, the man behind Kasrog, Recabinet and PluginUpdate has told us about a free app, smcFanControl, that can help your Mac run cooler. Shane says...
Anyone else who chooses to or has to run a Mac - you need smcFanControl (unless you're on a Mac Pro desktop or Hackintosh.) This free, open source app allows you to control your fan speed. This is critical, as due to intrinsic style-over-substance design practices at Apple (in addition to absurd thermal paste overspill in manufacturing), most Macs run their Intel CPUs at, above, or at least near their max heat tolerance limits. Download now and protect your investment!
smcFanControl lets the user set a minimum speed for built-in fans. It allows you to increase your minimum fan speed to make your Intel Mac run cooler. In order to not damage your machine, smcFanControl does not let you set a minimum speed to a value below Apple's defaults.
If you would like to get smcFanControl then you can download it from the usual sources or from the developer here. If you are running Mac OS 106 or higher then go for v2.5 which has added these features...
- New: Reduced energy usage on OS X 10.9 and OS X 10.10
- New: Support for Yosemite Dark Mode
- Fixed: Crash on OS X 10.9, when deleting Favorites
- Fixed: Various smaller fixes, improvements and code optimizations
Slower fan speeds also means quieter fans and running the fans slowly most of the time should mean they don't have to ever run fast and noisily to keep your Mac cool.
