M3 chips support
Hopefully we see a beta soon because I'd certainly love to be able to monitor these temps and setup fan curves. even the basic "full blast" and half blast don't work
I will soon get my hands on M3 laptops, stay tuned. Just ordered M3/M3 Pro ...
on an m3 - putting them on full blast only seems to work when they're already running (not in the orange zero state)
It doesn't, at least not on my M3 Pro. I would also note that even if I set it as @samdenty describes (while the fans are on), once the temperature drops down low enough it will still return to 0 speed mode even if set to full blast, so I'm assuming that the method used to disable automatic no longer works either.
Here's a test build, works on both M3/M3 Pro (displays sensors and controls fan speed). Not tested on M3 max yet (tech info welcome). macsfancontrol.zip
Can confirm that I can now see all of my sensors, but neither setting Full blast, nor setting a custom sensor based fan curve engages the fans. This is the base 16 inch MacBook Pro. Waited a good 5 minutes. Do you need something for debugging?
See attached. I set the settings back to Automatic, shut down Macs Fan Control, opened it again, set it to Full blast, waited one minute, then exported tech info.
Nothing visible or audible. Fans still off. I repeated the reset, close the software and open it again on battery power. Tech info attached.
Same issue, 16" m3 mbp, the app and the test app do nothing.
Please first try setting full blast, wait 1 minute and post tech info as described here.
The way it works for my testing, on M3, fan control only controls the fan speed but NOT whether or not they should be on or not. Basically half and full blast work, but only if the fans would be on in automatic. if automatic/default curve has decided fans should not be on, then fan control does absolutely nothing.
So in short, it seems the software is controlling the fan speed but not the on/off state of the fans. I can reproduce this 100% of time. As long as the fans aren't 0rpm in automatic, the manual settings work. if the automatic is in 0rpm, manual does absolutely nothing.
Looks like we have an issue on 16" models. Looking forward to get one for testing. Thanks guys
The same case I am experiencing with the 16" M3 Max MacBook Pro with 40cores GPU. (App not controlling fan on/off, but it does control speed) I am also noticing on my Mac, only 8 performance cores is showing and the temperature for GPU Core Average is displaying 7C/45F and stay still.
Step I did before generating log for your reference.
- Open the apps
- Full Blast
- Wait for ~30seconds
- Open Handbrake to encode a video with CPU
- Wait until fan automatically kick in(Setting still in full blast)
- Manually adjust the fan to 3500RPM(left, then right), it does able to control
- Stop handbrake
- Fan stopped automatically(Setting still in full blast)
Can confirm PP finding as well, gpu temp stick at 7, several cpu cores missing.
MBP 16" M3 Max - app cannot control the fan when the fan is off. When the machine is under some heavy load (eg. docker build), app can set the fan speed ie. full blast, but when the load is gone the fan automatically stops and app cannot control the fan again.
Hello guys, I wish this could be solved soon. I own MacBook Pro 16 M3 Max 14C 30GPU and facing the same problem that can't control macs fan. I render videos in premiere pro quite often and my MacBook gets very hot every time. I don't trust to system controled fans. Over time it can cause battery degrading in my opinion. Good luck.
@picinko If you use beta, you can control the fans in heavier loads, you just can't really control them in light loads because it only controls fan speed not fan activation and apple seems to kick fans on (at all) near the 70C mark, sometimes 60, not sure what makes apple choose 60 or 70. but once they are on you can control them. i have a temperature curve and everything setup and it works, just not til 70C. Ideally I'd like them to kick in around 55-60 (at low rpm) but that'll come later.
but during your rendering, yeah you'll activate the fans (and THEN fan control will take over).
Just use beta from https://github.com/crystalidea/macs-fan-control/issues/721
Hi guys, how is the process of development of M3 chips supporting version going? I am new on MacOS and I am having trust issues towards the high internal temperatures that I can get the laptop to run in sometimes. The fans still don't seem to active on their own...
The last tip from @MysticalOS does not work for me unfortunately ...
Currently there's no way to force turn on the fan(s) on 16" M3 MacBook Pro when system thinks it's cool enough 😢
Oh No, oh no, that's not good news. Do you think that is possible to make request for Apple to make changes in MacOS ? I'ts by hardware or it's inside system's code ? I express myself in a very layman's way sorry for that.
What would you (@kleuter) say are the average temperatures MacBook Pro can run on long-term not to sustain long-term damage on internal components? Temperatures on CPU, GPU or on the Chasis, whichever is fine. I want to play some games on it since it packs quite the punch - i.e. awaiting the launch of Death Stranding. I tried World of Tanks but the laptop gets quite hot, yet the fans never turn on. I have been using mine for over a month and so far, I had never heard the fans to turn on...
I found that many users even on older macs are facing the similiar issue. https://discussions.apple.com/thread/255184490 Is there any chance @kleuter that you could send request to solve this direct to apple support ? As you are a developer of an app they could maybe fix this in next update or allow to developers overrun system settings. When I use TG Pro the message is popping out about hardware disable fan control . -https://www.tunabellysoftware.com/support/tgpro_tutorial/#fan_control_t2
There's no chance (I think) that Apple will ever change its mind about this decision, so there's no use of writing them, I'm afraid
Fortunately, it does work in sense of kicking in fans as i need them when I most need them. when it IS warm enough to turn on fans, it turns them on higher as I need.
At this point just need remaining temp sensors and such fixed.
