I've found a shorter way to do this now. First, record your minimum speed value so you can go back to it. Then, just sent the minimum to the desired speed. No need to set the Forced mode, etc. For my model the original minimum is 1200 and the real max is 4650, so I can just do this: sudo ./smc -k F0Mn -w 48a8 It's now set to max speed. sudo ./smc -k F0Mn -w 12c0 It's now set back to normal auto mode with the original minimum. The danger here is that if you don't record / remember your original minimum speed, you might lose it. A reboot MIGHT fix, or a SMC reset perhaps, but.. just.. don't DO that.

wow. MacBook Pro 2011 late with oclp. maximum fan was actually 6200. now 7450 :D thanks

Is there a way to do this on an M2 Mac mini? My Mac mini gets to about 95˚ Celsius. The max speed is 4500rpm in Macs Fan Control. My old 2014 Mac mini could get up to 6500rpm with the command line SMCFanControl

Indeed you can! You prompted me to poke around and I now have my M2 running at 6500 rpm, 2000 over stock maximum. It appears that the trick in the comment of using F0Mn (setting the minimum no longer works, but setting the target does. I pulled the repo from my github (github.com/EverlastEngineering/smcMaxFan), built it in xcode and in the build folder I found the smc tool and ran: sudo ./smc -k "F0Tg" -w 0020cb45 That set my max speed to 6500rpm. You can use a calculator here for the math: gregstoll.com/~gregstoll/floattohex/ Be sure to check the box for `Swap to use big-endian`.

Interestingly, there is a key called F0Dc which hits 1.0 when my fan will no longer go any faster; that must be the PWM factor for the DC voltage going to the fan.

@@everlasting1 Do you happen to know what the theoretical maximum fan speed for the M2 Mac mini is? Just curious.

is there anyway to use that script on ubuntu linux?
@everlasting16 ай бұрын
Only if someone has (or you can) compiled the smc utility on linux.

Is it possible to do this in bootcamp too?

Hmmm, that's a great question. I don't know if you can access the SMC directly or not. If you can find something that allows you to access the SMC, I imagine the keys would be the same. Mac Fan Control has a Windows version, so it's possible to actually access it, so I'd say.. yes? :) If you manage to, let me know!
