9/13/2019 Smc Fan Control Settings For Mac Pro
The iMac version allows separate sensors to drive the control of each of its 3 fans and the extended MacBook/MacBook Pro version allows fan-control via the CPU and/or GPU temperatures (useful if you play games on your laptop). There are also some other minor enhancements (see the ReadMe files). What OSX is everyone using to with SMC Fancontrol Setting? Running well-written video software, a current-model MacBook Pro is using a.
Gaming on the rMBP under Windows 7 is a very good experience but I have noticed that unless I elevate the chassis there is a tendency for the automatically regulated fan speed to fail to engage a rising computational load fast enough to keep the CPU under thermal shutdown temperature (Tj max) and freeze the machine. This is somewhat inconvenient of course, as it means the CPU has reached a temperature that it should never reach, and also requires a reboot.
I know that the fans are capable of running higher than the highest they have been recorded to run which is in the neighborhood of 4900 RPM, they should be capable of going to 6000 RPM, which, even though it would be noisy would be keeping the CPU cooler, which is a good thing in my book. Here's a screen capture to illustrate. So I hope this makes it clear that Apple's fan speed scaling is a bit on the conservative side when the temperatures are high. From what I can tell, once you get the machine nice and toasty and the load 'stabilizes' it will generally be in a state of equilibrium where the CPU core temperatures hover in the high 80's and 90 degrees C, making occasional excursions above 100 degrees C.
So long as the 105 degree Tj Max point is not passed the computer keeps up with whatever game you're playing just fine. My understanding is that under OS X I can use the smcFanControl app to manually specify the fan RPMs, but I have not been able to find a similar way to control or fix the fan speed once I am booted into Windows. When I did this sort of experimenting on my Macbook Air there seemed to be a method which involved setting the desired setting in smcFanControl in OS X and then sometimes rebooting into windows would have the setting stick. This would basically get the job done if it works on the rMBP as well, but I'd prefer something friendlier.
Are there any fan control applications for Windows that will recognize and allow control of the Macbook Pro fans? So I went with the lubbo fancontrol and changed the config option as suggested above. I'm running windows 7 pro on my macbook pro retina late 2012, 2.6 i7. One thing you can do regardless of an extra fan controller is drop the CPU power. Go to Power Options Change plan settings (starting from Balanced) Change Advanced power settings.
Then in the Power Options popup window, I went to: Processor power management Maximum processor state, and set my On battery and Plugged in percentages to 90%. Got a bout a 20 deg C drop in temperature.
I posted about it here.
If your Macbook Pro fan is always on, loud, not working, or experiencing other problems like invariable fan speed, or excessive noise, then there may be several things you can try to fix this. Macbook Pro Fan Always On A Macbook Pro fan should always be on. However it should not be excessively noisy or running at a high speed all the time. If it is running at maximum RPM (usually about 6000 on a Macbook Pro), this indicates there is software running on your Mac that is stressing the CPU or GPU. Open Activity Monitor to see which apps are using the most CPU. You can also see which apps are using the most energy as well. Apps like Photoshop, Final Cut Pro, and VMware Fusion/Parallels tend to cause the fans to speed up, as the temperature of your CPU/GPU will increase when using those apps.
Disable Flash in your browser. Flash is now disabled by default in Firefox. In Chrome, you can use to disable instances of Flash (it still allows you to view Flash on a per-site basis as needed). It’s one of the biggest causes of CPU/GPU stress, and will no doubt increase your Macbook Pro fan speed because Flash is so intensive on hardware. Restart your Macbook Pro. If the fan is continually running at a high speed, try a Restart.
If a restart doesn’t work, try resetting the SMC and PRAM. The SMC reset especially may help. Find out how to. Fixing a Noisy Macbook Pro Fan If your Macbook Pro fan is loud most of the time, it may indicate its running faster than it should be, or there is something triggering it to do this. Make sure it is not clogged with dust.
Fans are noisy when they have to run faster, and it may be running faster because its clogged with dust. Dust will dramatically reduce the effectiveness of your Macbook Pro fan. It is quite easy to clean a Macbook Pro fan, you can even try to do it without opening your Macbook Pro by using a can of compressed air and pushing the air through the vents at the back of your Macbook Pro. If you are using external displays. Macbook and almost of Mac fans would be noisy if you’re connecting external displays, especially high resolution ones because your Graphic Card will be working with max performance which will make the fans noise.
Like, if your Macbook supports max 2 external displays with max resolution at 2k / each, then if you connect only 1 display – it would be fine, but if you connect 2 external display at 2k resolution - Your fans maybe noisy then. The solution here is connecting less external displays or lower resolution, or if you really need those high resolution external displays, upgrade your Macbook then. You may need to replace the fans. Old fans are typically louder than new ones. If your fans are always noisy, even when not running very fast, this would indicate that the fans have simply worn out. Controlling Macbook Pro Fan Speed By default, the firmware in a Macbook Pro controls the speed of the fans. Apple pre-determines when the fans should kick in at high speed if the CPU/GPU are hot.
Apple don’t provide any friendly interfaces to control the fan behavior manually, so you have to install third party utilities to do this. Install Smcfancontrol Smcfancontrol gives you the control to decide what speeds your fans should be running at. You can set favorite settings for the left/right fans in your Macbook Pro.
By default, on ordinary load, the fans in a Macbook Pro run at 2000 RPM. I’ve always run mine at 3000 RPM, to keep the CPU/GPU temperatures extra low. If you are running Flash, a game, or something else that’s CPU/GPU intensive (video encoding, compressing files, decompression, image manipulation, etc), then you can choose to select your Higher RPM favorite setting, e.g. Although this will make the fans louder, it will keep your Mac a lot cooler.
Install iStats The program, that you can run in the Terminal, gives a useful overview of the current CPU temperature, Battery Health, and Fan Speeds.
