Kkillian has released iCyclone, an open source donation-ware program that allows users to manually set the minimum speeds of built-in fans for Apple’s MacBook and MacBook Pro Intel-based laptops.
The program allows a custom spin rate to be set as well as an optimal rate to be found automatically while not spinning below the hardware’s recommended specifications in order to protect the hardware.
iCyclone’s source code is available for download while the program itself is a quick 544 kilobyte download from the uber-useful MacUpdate.com.
The program is available for free albeit the author asks for the occasional donation via Paypal.
iCyclone requires an Intel-based MacBook or MacBook Pro laptop and Mac OS X 10.4 or later to run.
