(2019) 16" is HOT & NOISY with an external monitor! :(

[kaans]

Yeah, 14W consistent, regular usage, it rarely jumps above

I also saw an 6W in the logs too, but that was before connecting the external monitor I assume

Theoretically, I don't think anything is standing in the way of a fix/improvement anyway, but for some reason, we still suffer :/

And the speed of the fans?

Just tested for you, had to install Macs Fan Control, otherwise HwInfo64 doesn't show the fan speeds

On idle left/right 1700/1800 rpm (This is right after MacOS was running, so the temps were 60C already when Windows was opened)

I also tested the fan speeds / temperature response with Batter Saver / High Performance, with Prime95, Unigine - the default fan profile is super sad, with battery saver, the CPU's were around 2.4 ghz, they obviously didn't heat much, the fans just stay at 1700/1800 for ~1min until CPU reached 90C+'s - the fans have a very relaxed / long term / delayed response (Edit: My interpretation, the device is calibrated to heat up)

Likely what you have there is underclocking of the GPU that the drivers support. I don't think macOS supports this.

By the way, I just switched to Windows/Bootcamp to release some updates

The GPU was using 14W, and the temps were 57-60C to start with, which is just incredible

When you just slide the power profile from the Taskbar to "Maximum Battery Life" - the experience was just incredible, the average temp was still 64C - but the maximum temperature was around 70C's

Also one easily noticeable thing, on MacOS - with an external monitor, I almost lose 1% every minute - on the bootcamp, I stayed for 2 hours - and used only 45% with the external screen on, so basically, with lighter tasks, no video playback etc. - so on terms that Apple can understand, I got 2.5X Better Battery Life on Windows

14W was still meh, but honestly, first time with this Macbook and an external monitor, I felt safe to just let it be, on Windows out of all places, it was very unexpected

This is a tangentially related question but I've currently got the 5500m 8gb w i9 and find 1) turning on HDR support in preferences when using my LG display is completely unusable, the colors of everything are so whacky and 2) 4k content on YouTube via Chrome always has a low framerate. I have turned of hardware acceleration on Chrome as I found that helped w lower fan noise, also have Turbo Boost off. Seems odd to me this setup still wouldn't have enough juice to render better visuals. Or are those compromises to get lower noise the cause?

HDR on LCD monitors is a joke, in general. Nothing to do with the MBP, I believe. I have an LG 27UK850-W and HDR looks horrible.

And room temperature.

 

[ateslik]

To be honest, I'm quite jealous of 5600M's if they don't heat and also perform that well, comparatively, our 5500M's are just a hinderance, the systems would perform better with just internal GPU's

Do the 5600M’s have the same problem? If they don’t that may change things for me.

2.5X Better Battery Life on Windows

Damn, shots fired! lol

 

[kaans]

I don't know.

If you check the thread, some also come claiming their 5500M's work with external monitors, so I'd wait someone with detailed analysis to post actual figures - the difference might be small, the 5600M gaming thread looked promising, but I didn't see anyone with 5600M idle tests yet, here

Room temperature is 25C, it's a direct comparison between MacOS and Windows anyway, Windows is slightly better managed - the issue is there, but it's more manageable - both GPU and CPU

Likely what you have there is underclocking of the GPU that the drivers support. I don't think macOS supports this.

If you check "sudo powermetrics" - the GPU is always underclocked on MacOS - 350mhz

After a better analysis now, with a more clear mind, I see that the problem on MacOS is the WindowServer CPU usage, it's using 20-30% - and the heat probably actually comes from the CPU - Windows was more lightweight, so I assume that's why things were cooler

I can't check the watt usage of the GPU on MacOS by the way, iStats seems scary to me, I avoid closed source heavy products as much as I can, and it's not reported on anywhere easy :/

Has anyone managed to get their hands on the new 5600M powered 16" MacBook pros?

Really curious to see if they fixed the issue with the overheating.

 

[OSXphoto]

Hey people I just hopped over from the Apple discussions forum to this thread. Did you get anything useful or is there a page # or pages of particular interest?
Thanks, Peter

 

[interbear]

Yesterday - with external monitor connected (USB-C) - temp up to 67%, fans running at 5,500rpm, noisy as ****.

Today - no monitor connected - temp up to 47%, fans running at 1,750rpm, quiet and delightful.

Same apps running (MS Teams, Office for Mac, Outlook, Chrome, Safari, Monday, Apple Music).

No response yet from Apple support engineer escalation but if they tell me that the heat and noise is "expected behaviour" when connecting an external monitor, I may explode with rage induced heat and noise myself 🤨

I returned my 5500M model and have been using the 2.4GHz/32GB/5600M/2TB model for a few days now. No issues so far using a 1440p 165Hz external monitor. anyone know of an alternative to iStats? I cant get power consumption metrics with the 5600M from iStats.

Do you use it with the lid open? If so what about the fans and what is the temperature?

I’ve been using it both closed/open. Usually open for audio production work for extra screen real estate and closed for general web browsing. It has been getting hotter where I’m located so I've been seeing:

(sudo powermetrics)

MBP Open
CPU Die: ~55-85C
GPU Die: ~55-78C
Fans: ~1800-3000 rpm.

MBP Clamshell (Closed)
CPU Die: ~50-75C
GPU Die: ~53-69C
Fans: ~1800-2500 rpm

This was just the min/max after watching terminal while working on light audio work in Ableton with a Twitch stream and a few other tabs open/running simultaneously. Using a 1440p 165Hz monitor and MBP’s display set to “Default for display”. Obviously nothing scientific, but it’s a general idea of what I’m experiencing. Might be worth mentioning that I’m using stock MacOS Catalina 10.15.5 fan/CPU management (not using apps like Macs Fan Control/Turbo Switcher).

When just web browsing with multiple tabs in open mode, I’m consistently seeing CPU/GPU temps of ~50-55C at 1800rpm. CPU temps are almost always higher than GPU temps. I don’t know if this but is relevant to my stats but I’m running all my peripherals, monitor, and power over a single cable from my HP Thunderbolt 3 G2 dock (It’s the only cable plugged into my MBP).

edit: Capitalization + more context.

I think your temps and fans are similar to mine mbp 5500m. I haven’t seen fans above 5000rpm with lid open with normal usage. I’ll check it out once I’m back from holidays.

 

[bill-p]

That looks like what I'm seeing with my 5500M computer. I also don't see the "max fans as soon as monitor is connected" issue that most are seeing despite the GPU jumping to 20W immediately.

Looks like they haven't fixed the issue with the 5600M after all. And all indications are pointing to it being a driver issue as well at this point.

Email iStats and ask. When I got my gen10 13" iStats couldn't get the power consumption details. I emailed them and they sent me a link to a version that could.

 

[OSXphoto]

I just posted this in another thread but have been active here too so sharing. Got from Max Tech... They can't yet measure the wattage of the Radeon High Side, iStats isn't reporting it. But he sent me his temps while browsing for an hour and plugged into an Apple 6K XDR (attached). At least compared to my i9 5500m, I'm usually around 60-63c when browsing, etc, lid open, external display. Maybe the 5600 design reduces heat after all?

Hi Cibby, I noticed your question a few pages back. I've been in contact with iStat Menus developers b/c I could not see any power stats on my 2020 13" 2.0GHz w/ 16GB RAM. Within 24 hours (on jun 25th) they sent me a beta which offered a massive # of readings. I suppose this might also work for the 16".

Edit: that's a coincidence, I hadn't noticed ateslik's message just yet, must have crossed, sorry.

My 16 inch pro gets super hot when connected to the external monitor but I don't ever hear fans. is it not getting hot enough? I checked the diagnostics on restart and shows no issues.

I’m in the same boat as you. The fans don’t kick on at all for me but it gets extremely hot to the touch just being connected to a monitor. My concern is the longevity of this machine being used every day for work and getting hot every time.

For me it’s 45 to 55 degrees C in clamshell mode. Goes above 55 if im doing anything besides web browsing. Wattage for the Radeon is around 5w in clamshell. Jumps to 20 watts the second I open the lid. Temps also jump as well.

There's a really weird fan profile, on sudo powermetics, I also see 1700rpm from time to time, even though the temps are exceeding 70C's

Currently it's:

CPU Thermal level: 66
GPU Thermal level: 16
IO Thermal level: 16
Fan: 2920.51 rpm
CPU die temperature: 68.27 C
GPU die temperature: 67.00 C

Even though GPU is heating things up, CPU is always like an amplifier - I'm in a weird place, I don't want to give root password to the Turbo Switcher app, but since it doesn't need csrutil disabled, the developer probably got kext signing from Apple and has been signing the kext (or maybe he does it in a different way? I don't know) - I have this open source project compiled: https://github.com/syscl/CPUTune - yet since my developer profile doesn't have kext signing, it doesn't even run on my own machine without csrutil's kext disabled, which pretty much disables the protection - so it's heat vs security, living with heat

Yeah it's ridiculous based on the amount of cash dropped on this. By the way, what app do you use to check the temp? My last pro was from 2013 and still works so never really delved into this kinda stuff.

I would appreciate if you could provide us the outcome regarding the power consumption with the new version of iStats when available. Tjx

I use Istats to keep track of the temps. I’m leaning towards keeping the machine. Just worried about the constant heat. Absolutely ridiculous that Apple isn’t acknowledging this.
