By setting the minimum speed to 800rpm, the lowest ever achieved rpm that I got is around 960rpm.Īfter rebooting, the minimum fan speed got reset (by the system supposedly) to the original 1200rpm. It seems that the fan and its control logic can’t go well below that. Lowering the minimum speed below 1000rpm does not yield the desired results. Yet, there is still considerable airflow and everything looks and feels great. This results in almost complete silence in my environment. Applications/smcFanControl.app/Contents/Resources/smc -f Reading out the smc info now looks like this: Press the power button, and as soon as you power up the laptop, hold down Command-Option-P. If you need further explanation, the GitHub repo provides a detailed readme.Īfter that, use Macs Fan Control to reduce the speed manually to 1000rpm. To reset your NVRAM, you use exactly the same procedure you once used to reset PRAM. This writes the for 1000 (0fa0) to the smc key F0Mn (minimum speed of fan 0). Applications/smcFanControl.app/Contents/Resources/smc -k F0Mn -w 0fa0 You can and will destroy stuff and I won’t take any responsibility, but here is what worked for me (assuming that you copied smcFanControl to Applications directory): Manipulating the fans could cause overheating and permanent damage. Which could irreversibly damage your computer.
This tool will allow you to write values to the SMC The factory reset won't delete any of your files on Google Drive or external storage device. Before you reset, make sure to back up your files on Google Drive or an external hard drive. From here on you must read the following first: Warning A factory reset erases all the information on your Chromebook's hard drive, including all the files in the Downloads folder. Its called smc and is also available separately on GitHub. What you need is a utility that is included in the smcFanControl tool. Luckily I found a way around that and reduced the minimum to 1000rpm, which is considerable less noisy! It makes all the difference to me. I downloaded Macs Fan Control, but you can’t reduce rpm below the minimum 1200 (but you can go up to 2700). So the default 1200rpm can be seen as a static value: it doesn’t go above or below that no matter what you do to the system. It seems that on my low spec iMac, the regular (Apple auto-controlled) rpms never get regulated above those 1200rpm, even when running Unreal 3D benchmarks. But then, you hear the fan “idling” at 1200rpm resulting in quite a strong airflow and distracting noise no matter what your system load is. I simply want to remove it, but each time I delete the app and. It seems to think the base speed for my 2012 2.6 mini is 2300rpm (which was a setting I used once) and does not give me options to move the slider or input a value below 2300 even thought the default speed is 1800. Unbearable in a quiet environment.Īfter installing the SSD, the speed and noise improvement are tremendous. My SMC Fan Control app seems to be corrupt. However, apart from the HD being way to slow, it is also very noisy: there is a hiss type of sound and rumble from the rotational mass.

Not an easy decision since you need to cut the Mac open. I finally replaced my hard drive in my 2015 iMac 5k with a Samsung 860 SSD. I saw something online that suggested that there may still be some power that is not fully discharged in the regular reset procedure.NOTE: This guide apparently only works up to Catalina and does not work on Big Sur. The only other suggestion I would give you is to do the SMC reset procedure, but leave the battery out for a long while (1-2 hours), then hold the power button in for 5 seconds again, then replace the battery and start up. I can't say that this proves that the SMC was reset, but it's interesting. I did that too and I still get a shutdown cause of "0".

If you've got burnt thighs from an old MacBook Pro or you notice that your computer is always overheating and crashing from. I usually do a PRAM reset immediately when powering up after resetting the SMC. smcFanControl lets the user set the minimum speed of the build-in fans. After using the SMC reset procedure, it ends with "0". It ends with "5" after a normal startup and also after resetting the PRAM.
I you look at the kernel.log in Console after starting up, about 30-40 lines after startup begins there is a line that says:Īpr 26 10:18:13 localhost kernel: Previous Shutdown Cause: 5 I poked around a bit and did find something interesting.
I didn't find anything with a definite way to tell. I was curious about a way to confirm whether the SMC is actually reset.

If your firmware version is lower than the one listed in this table, you should upgrade by following the link provided. Note: In some cases System Profiler may report later versions of firmware than those listed below if this is the case, your computer does not require any additional firmware updates. According to this document: EFI and SMC firmware updates for Intel-based Macs, SMC version 1.32f8 (SMC 1.2) is correct for the late 2008 aluminum Unibody MacBook. Your processor speeds are different, but I don't know if that should make any difference. It's the 2GHz Processor, SMC version 1.32f8. I have this model from September or October 2008.
