MacBook Pro SMC 1.3 improves fans under load

Owners of prior MacBook Pro systems were given an update late last week that should improve their tolerance for heat.

SMC Firmware Update 1.3 (833KB) gives 15- and 17-inch MacBook Pros from late 2007 and early 2008 improved fan behavior in high workload conditions.

Applying the firmware requires at least Mac OS X 10.4.11 for late 2007 MacBook Pros and 10.5.7 for the early 2008 models, which came preloaded with Mac OS X Leopard.
