MacBook Pro (16-inch, 2019) Support #96

@kleuter I did, with similar problems; I've also tried iStatus Menus. All 3 have similar issues; they can't read the actual status of the fans or can't control them. |
|
@aanttila strange they claim full support |
|
So it does work now, but only for a single custom setting without paying the license fee; I prefer smcFanControl for the simpler user interface and cost (free), which is why I submitted the bug for this project instead of ignoring it and using a different software product. |
|
Would love to see this happening :) The new Mac wants to be quiet more than be cool so I have to find a solution while waiting for a hero to make SMC compatible with the new Mac. But I'm happy to report the iStat Menu is working, it's a bit of a waste getting it just for the fan control but it works.

No one got it running yet? |
|
when running this forces manual mode on the fans allowing you to set custom speeds on the fans. for the mbpro it has 2 fans so: the 36b0 is is hex for 3500 dec left shifted by 2: probably need to dig into the code but I don't really know any objective-c. |
|
Any luck? @mikeziri |
|
@aanttila When are you open sourcing yours? |
|
unfortunately no. the smc keys must be new. |
|
Can confirm that latest version (v2.48) of TG Pro can control fans on MacBook Pro (16-inch, 2019) |
|
Hey folks, I tried using smcFanControl on my MBP 16 2019, and as I can see you are mentioning SMC keys have changed. I went ahead and installed Mac Fan Control and it did work for me. I am on the latest GA Mac OS version. Interesting thing is that the logs of the Mac Fan Control app dumps the values of the SMC Keys. Could you please take a look at my logs snippet.
|
|
@pokekrishna Huh that is very interesting. Thank you! |
|
yes, it might be affected by the recent macOS update. Both smc & iStat Menus stopped working, only Macs Fan Control works now. |
|
I tried macOS Fan control and hate to say that it is a little bit too complicated for me. Can anyone share their fan control settings with me maybe? All I want is to increase the minimum fan speed so that it is a little bit cooler by default. What confuses is which sensor to take for measurement. How to include CPU + GPU to the calculation and keep fan RPM in sync? |
|
I just installed smcFanControl via brew cask. When I open it showed me a warning message of "this software is not tested on your machine but if you follow our instructions it will work". Which is a fair warning. However, on the bar, it just shows "47C and 0000RPM". I understand that it's not tested on this laptop specifically. When I install htop, it says run with sudo to run all features. Is there anyone who have tried running smcFanControl with sudo? |
|
Has anyone figured out the smc key for the Macbook Pro 16 to increase max fan speed? |
|
Not sure if it's the maximum, but here it is something useful: |

Thanks Denys for getting back to me.
I used similar values that seem to work but will try yours as well:
smc -k "F0Md" -w 01
smc -k "F0Tg" -w 0060ea45
smc -k "F1Md" -w 01
smc -k "F1Tg" -w 0060ea45

Oh yes, don't use mine, they're not bit shifted (LOL) |
|
Ok your values set the fans 100 rpm faster. Thank you!!! :)
FYI: to reset back to system controlled speed I start macsfans control.
Any way to do this with smc -k?

How do you check your RPMs by the way? |
|
istat menus. It was worth the investment as it does all the stats I
need, fans, temperatures, network, and amazing at showing which process
is using the cpu, disk, or network. Macos activity monitor only shows
the total disk transferred bytes not the current top user.

Wow thank you for the full calculation script!!! :)

After checking, your values (|0060ea45| = 7500 rpms (float 32)) are
correct, but mines are overflowing (?) and thus causing the fans to
spin faster.
Useful bash functions:
|utils.sh|
SMC="/Applications/smcFanControl.app/Contents/Resources/smc"
function get_bytes(){
$SMC -r -k"$1" | grep -E -o'bytes [0-9a-f ]+' | cut -d' ' -f 2-| sed -E's/ //g'
}
function hex_to_f32(){
python3 -c"import struct; print(int(struct.unpack('f', bytes.fromhex('$1'))[0]))"
}
function f32_to_hex(){
python3 -c"import struct; print(struct.pack('f', $1).hex())"
}
|get.sh|
#!/bin/bash
set -e
. utils.sh
F0_TARGET_BYTES=$(get_bytes "F0Tg")
F0_MIN_BYTES=$(get_bytes "F0Mn")
F0_MAX_BYTES=$(get_bytes "F0Mx")
F1_TARGET_BYTES=$(get_bytes "F1Tg")
F1_MIN_BYTES=$(get_bytes "F1Mn")
F1_MAX_BYTES=$(get_bytes "F1Mx")
F0_TARGET=$(hex_to_f32 "$F0_TARGET_BYTES")
F0_MIN=$(hex_to_f32 "$F0_MIN_BYTES")
F0_MAX=$(hex_to_f32 "$F0_MAX_BYTES")
F1_TARGET=$(hex_to_f32 "$F1_TARGET_BYTES")
F1_MIN=$(hex_to_f32 "$F1_MIN_BYTES")
F1_MAX=$(hex_to_f32 "$F1_MAX_BYTES")
function print_fan(){
NUMBER="$1"
TARGET="$2"
F_MIN="$3"
F_MAX="$4"
echo "F$NUMBER: $2 ($F_MIN, $F_MAX)"
}
print_fan 0"$F0_TARGET" "$F0_MIN" "$F0_MAX"
print_fan 1"$F1_TARGET" "$F1_MIN" "$F1_MAX"

Tried building and running the latest (commit e1bd672). My fans immediately went to full blast and wasn't able to control it. Had to turn the machine off :D |
I just received my new 16-inch MacBook Pro (MacBookPro16,1) with an 8-core 2.4 GHz CPU, and of course, I wanted to customize the fan profiles using smcFanControl. Unfortunately, there seem to be enough software/hardware changes that fan speeds are reported incorrectly and cannot currently be modified.
