MBP14 Max owners - what are your typical idle and working temperatures / fan-speed?

[Fomalhaut]

For those of you who use some kind of temperature and fan-speed application (e.g. TG Pro or iStat Menus), I'm curious what your typical MBP14 M1-Max temperatures and fan speeds are.

Mine sits at around 48-50C most of the time (CPU average for all cores), and even after starting up or waking from sleep, seems to be at >46-48C almost immediately. GPU temp is very similar when connected to 2 monitors.

Under system control, the fans seem to go from 0 to about 2400-2500 as soon as CPU average temp gets >55C and are inaudible nearly all of the time. It got to about 75C maximum during heavy video decoding but even then I could only just hear the fans (probably in low-mid 3000s rpm).

With the fans turned up to maximum, and with light browsing use, the CPU average drops to about 42C, and I don't think I've ever seen it below 40C

Quite similar in my case - my ambient temperature is 22-25 deg C. The fans rarely spin up when the Mac is idle or doing light work.

The fans might run up to about 3,700rpm when the CPU cores are at 95 deg C or thereabouts under sustained multicore load, which is audible but much quieter than the 2019 i9 under similar load.

Very occasionally the fans spin up to 6,000 rpm which gets really loud, but that is because the fans don't spin up for some time when the CPU load is already at maximum load. I wish the fan controls can turn on the fans earlier. They ramp down quickly when the CPU temperature starts to decrease.

Thanks. You can set the fan profile to your own custom speeds with tools like TG Pro and iStat Menus.

My ambient temps (summer at the moment) are quite high because I have no air conditioning in my home office, just fans, and when it a bit cooler, my idle temperatures are closer to 43-45C.

I've only heard the fans once when I was using a very CPU intensive video player that was decoding highly compressed video. Even then, I think the machine was doing something else at the same time because I've never been able to reproduce the same fan speed. I agree that even at maximum, around 6000rpm, the fans are somewhat quieter and less irritating than the MBP16.

I did use the fan profile sometimes, but more often than not it just never crossed my mind - I would usually be pretty occupied with data wrangling when that happened. Thankfully those episodes were very occasional so I can live with them.

Does anyone know if Apple silently changed the fan profile of the 14" MBP?
When I got the laptop at launch back in Oct, the fan would keep at 0 RPM all the time, unless under a really heavy load, like rendering video or opening a heavy load project with tons of plugins in DAW.

Recently I notice the laptop fan has been spinning at 2300-2500 rpm when I open like 10 youtube tabs in Safari or download large files over the ethernet.

The ambient temp has been around 16-18C recently, actually colder than back in Oct and Nov, so this makes me worry about the noise I will be getting during summertime.

I wouldn't worry - my ambient (summer here) is about 26-28C and the active temps hover around 48-50C (CPU average) with fans at 0 rpm. I have about 40 browser tabs open, and do a fair bit of file copying, although not large files. I don't think Finder is terribly CPU hungry, but large copies will raise the CPU temperature a few degrees (3-5C maybe?). My fans don't come on until about 55C, at which point they seem to go straight to 2300-2500. Do you have an app to measure your temperatures?

iStat Menus! I’m an older dude and close programs I’m not using at that moment! Besides an old audio guy I use a patch panel replacement LoopBack! To spice up Zoom Calls I use th digital cart machine program Farrago[/url]!

Are we actively looking for problems?

Always! I should add that the yellow memory pressure appears to have no noticeable effect on performance, so I'm not exactly concerned - just curious!

So you bought a product for the purpose to nitpick?

That is confidential information that I do not feel comfortable giving to you about my ultimate 14" m1 max, 32-core gpu model with 64 GBs of RAM in Silver.

I should have included the “/s” flag for your benefit…

But of course, the sole purpose for my tech purchases, and the only pleasure I derive from them is to find issues and then complain about them on Internet fora…

oh…and…/s ?

ambient temps about 20C with my M1 Pro 14" MacBook Pro operational temps start at 29C settle around 40C - with an average workload peakout @ about 50C, have only EVER had the fans turn on once and they were barely audible

Thanks, so it looks like about 5-10C cooler than my M1 Max, assuming we have similar usage.

Moderate load such as video conferencing raises the temps to about 53-55C

Mine is the 32-core GPU 14" Max. Just doing some web browsing in Safari right now:



I often leave "Low power mode" turned on because it is still plenty fast...and then just uncheck it when I'm doing something that requires 100%. But I like the cool and quiet operation until that point.

My highest temps are similar to the other posts here; but only reached when I'm doing something very CPU+GPU intensive; and with "Low power mode" unchecked. I have to say I really like the range of control Apple gave us. You can run silent and cool or all out full wattage. Either way it's still not that loud.

That's quite cool compared to mine (24-core M1 Max). Is this in "low power mode"?

Yes. And about 19C ambient. I turned off "low power" just now. It doesn't seem to be creeping up much. Maybe 3 degrees. Main difference is I see more spikes up to like 8 to 12 watts. This is just web browsing in Safari with a couple other apps open and dropbox syncing some files in the background.

My temps are little higher. Then again, my thighs have enough hot lean meat to feed a dinner party!
