![]() Reading hardware information from command line with built-in tools.The above article and the script it contains was designed for Mac OS X 10.4.3. This article, get sensor information, shows how to use ioreg to extract the fan speed information with: ioreg -c IOHWSensor | grep -B3 -A11 '"type" = "fanspeed"' SMC API in pure C: /beltex/libsmc iStats Ruby Gem for Mac stats: /Chris911/iStats smcFanControl tool to control fans in Objective-C (this. ![]() See Can I get the CPU temperature and fan speed from the command line in OS X? Pre-Mac OS X 10.5 Other tools and applications exist, including Temperature Monitor. This is a computationally expensive process, even when run for one second. ![]() Spindump requires administrator privileges and when run manually, spindump samples user and kernel stacks for every process in the system. This article, OS X: Current CPU temperature on command line, talks about the project and how to extract the fan speed: smc -k TC0D -r | sed 's/.*bytes \(.*\))/\1/' |sed 's/\(*\)/0x\1/g' | perl -ne 'chomp ($low,$high) = split(/ /) print (((hex($low)*256) hex($high))/4/64) print "C\n" ' smcFanControl is vulnerable to a stack-based buffer overflow, caused by improper bounds checking. The open source project Fan Control includes a command line tool that provides fan speed information. Follow the X-Force Vulnerability Report for CVE-2008-6252. For those wondering, the minimum default fan speed is 1,000 rpm for the 15-inch MacBook Pro, 1,500rpm for its 13. Notice the light on your mac charger change in colors.

What you need is a utility that is included in the smcFanControl tool. It appears no tool, installed by default on OS X, exposes this information through the terminal. smcFanControl manages your Mac’s fans responsibly to avoid damaging it. Since Mac OS X 10.5, you need to use a third party piece of software to access the fan speed information. Script changes SMC key BCLM (Battery control level maximum). See the smc manual page for more options. It uses smc-command binary from smcFanControl project for SMC keys access smcFanControl. You can use smc to get fan speed information via Terminal.app: smc -f You mention in your comments having smcFanControl installed this open source project includes the command line tool smc.
