To recall the set, choose it from the Fans menu in the sensor menu bar item. You can now edit the various fan speeds you’d like for this set.
Open the iStat Menus app and go to the sensors tab. If you’d like to create a set of fan speeds that can be recalled at any time, this can be done with fan set. With the fan control set to System Controlled from the Sensor menu, iStat Menus will not control fans at all - your Mac’s fans will act as if iStat Menus is not installed. #Fan control mac manual
Manual fan speed sliders in the Fan menu in the sensor menu bar item. There are four main modes of fan control in iStat Menus. iStat Menus can’t lower fans below the speed the System Management Controller (SMC) would normally use, but it can raise the fan speeds. I strive to keep chips (CPU, GPU, Airport Card, etc.Using Fans iStat Menus can help control the speed of fans in your Mac. my understanding is that hard disk temperatures should be kept below 113F/45C I'd much rather run the fan at a higher speed than suffer high temperatures (the ol' "rule of thumb" in electronics was - and I'm going way back here! - for every 10 degrees Celsius rise in temperature, you half the life of the semiconductor) light usage), I wouldn't want any fan to be running at any more than 1/2 of its maximum speed and, ideally, only at about 1/3 of it's maximum speed while doing basic browsing, email reading, etc. While I'm no expert on the subject and/or the components used in any of the Macs ('though I do have an electronics background), my decisions are based upon the following: Note that the steeper the slope of the graph's "control" line, the more rapidly fan speeds will be increased as temperatures rise (and vice versa). Raising the Lower Temp Threshold will control/raise the temperature at which Fan Control begins to increase the fan speeds (based upon the current temperature from the applicable sensor).ĭecreasing the Upper Temp Threshold will control/lower the temperature at which Fan Control increases the fan speeds to their maximum (based upon the current temperature from the applicable sensor). Though I do regularly run tasks that tax both these systems (i.e., keep both processors sitting at 50-70% usage for tens of minutes), I don't do anything that stresses the GPU on either of them.īTW, if you want to track temperatures, I've found Hardware Monitor to be an excellent application. #Fan control mac pro
The temps on my MacBook Pro normally sit with the CPU (diode) sensor at around 120F/48.9C, increase to around 140F/60C when moderately taxed and have seldom exceeded 170F/76.7C. With these settings, the HD in our iMac stays below 110F/43.3C (other temps were not an issue and stay similarly low). The current settings on my MacBook Pro 2.33 Core 2 Duo are: Settings will vary depending upon your environment and system usage patterns.
e.g., to generate a version for the Mac Pro that uses different sensors to control different fans (or groups of fans).

I've also tried to make it easy for anyone who might want to modify the source code and adapt it to other systems. (The GPU-based operation can be useful if you play games.) There are some other minor enhancements, noted in the Read Me file. The MacBook/MacBook Pro version allows use of the CPU and/or GPU temperatures to drive the fans. The iMac version uses separate sensors to drive the control of each of its three fans. These versions also have some extended control capabilities over the original FanControl. The result is that I've generated two new versions of Fan Control, one for the Intel-based iMacs and one for the MacBook/MacBook Pro. To that end, I decided to modify the open source (GPL) FanControl to work with our iMac.
#Fan control mac upgrade
We've used various applications to control the fan speeds on different systems but, with the upgrade to 10.5, our Intel-based iMac was left without a fan-control solution that worked adequately. We take great care to ensure that our systems run with reasonable temperatures as that helps extend their lifetimes.
