High GPU and CPU temps on the new 15 inch MBP

[Macaman]

What is the idle temperatures of the new 15 inch MBP and whats the temperature during load? In Luis Rossmans latest video, the new MBP CPU (2.7 Ghz) idle as high as 55-60 degrees and during benchmarks reached 100 C. The GPU also hit over 80 C during the Unigine benchmark he did.

These numbers seems a bit high, I got the impression from reviews and statements that the idle CPU temperature should hover around 20-25 C, while the GPU stays at around 70 C and CPU maxing out at 65-70 C with fans blowing att nearly full speed.

Luis notes:

Interesting points:
1) When doing an ffmpeg encode, CPU goes to 99c. No throttling that I saw in a cool room after 5 minutes, worked at 2.90 GHz, this was the 2.7 GHz model.
2) When running Unigine, it heated up more than ffmpeg, to the point of keys being considerably warm.
3) When using the Powerbit USB-C dongle, video worked! Video did not work on the 13" with this one, or wifi, but wifi/video works. HOWEVER, with the non-Apple USB-C dongle, I was limited to USB 2 speeds on my HDMI capture hardware.


The stated CPU idle is at 33:18, GPU benchmark is at 52:14 and the CPU benchmark is at 58:10.

Post your temperatures below

it will depend on the outside temps, the room you are in.

My 2016 was idling at 23 etc this morning when it was cold, now its 36.

I have a 2.7 2016 and 2.8 2015 side by side, both are 36 degrees right now idling next to each other

under load my 450 dGPU is around 70-72C

 

[Macaman]

Ye, your temps seems to fall within the normal range. I dont really understand how the MBP could idle as high as 55-60C. Even if the room is warm 60C idle temp is too much. Maybe a faulty unit?

 

[MH01]

interestingly just ran a quick handbrake conversion and the 2015 hit 98 under load while the 2016 only hit 55.... 55 degrees seems very low for a three minute handbrake run

 

[Macaman]

Did the 2016 MBP hit 55 degrees? You wrote 2015 two times

2016 hit 98?

 

[Macaman]

98 C is not good.... Even if the thermal CPU limit is set around 105 C, the surrounding hardware might take damage by prolonged exposure from that kind of heat. The CPU won't of course be working near 100% capacity at all times, but if you do some heavy CPU taxing tasks every day it all adds up over a longer period.

Seems like every Macbook Pro ever.

True, but these temperatures seems kinda weird since the new MBPs apparently should be running cooler than before. I have not yet recieved my new 15 inch MBP so I cant neither confirm or deny any of these benchmarks unfortunately.

I just tried the usual Big Buck Bunny as a .mov file and did a quick handbrake conversion to h264. It was very fast, however the temperature rose from 57 degrees idle to 86 degrees. Fans did not kick in or spin any faster. That is somehow scary.

Edit: 15' baseline 2016 model.

2016 hit 98?

Oops 2015

That was my typing mistake, 2015 hit 98 while 2016 hit 55

Oops 2015

Can you do some CPU intensive task that takes longer time to finish, just to see what temperature the CPU is hovering around? 55 C is nearly half the temperature in comparison to what Luis got in his benchmarks, doing an ffmpeg encoding.

I would be really happy if the CPU temp would stabilize around 60-70 C, that is an acceptable temperature zone for the other components.

Yeah agree. Let me run something else

I chose some heavier settings and encoding on handbrake took 10 minutes. It hit 93,2 degrees celsius max and was about 90 - 92.8 for the rest of the encoding. I don't think I like this. The fans were kicking in more noticeable this time, but they are still pretty damn silent to me.

I agree, 92 celsius is way higher than what the earlier reviews has stated. I did notice that some ppl has done a SMC and Nvram reset even though the laptop is new to resolve some problems with the fan curve. Could you perhaps try that?

 

[MH01]

Okay.

First of all istats install on the 2016 is choosing CPU promimity sensor , and on the 2015 CPU die, explains the issue I was having.

Having set both machines to CPU die

2015 2.8
idle: 34
Load : 95-98

2016 2.7
Idle : 38
Load : 92-94

What RPM did the fans spin at for the 2016 MBP during the test? Was the fans at max speed?

So the fans don't even change till it hit over 91 degrees.....and slowly build up over a few minutes to 5800....now 5900....... temp this time is 94 degrees

Ok, kinda disapointing. The laptop hits well over 90 degrees with the fans at almost full speed...

Alot of the reviews said that the new 15 MBP:s did run very cool with the very much improved cooling system, even though the laptop chassi is slimmer than before. I was actually suspicious of these reports. It seems that we now can confirm that the new 15 MBPs hits around the same CPU temperatures as the old 15 MBP and is not so much of an improvement.

SMCfancontrol is probably needed to make the fan curve more aggresive aswell.

Having played around with the 2015 and 2016 today, same same to be honest, the 2015 runs cooler ideling , the 2016 runs about 4-5 degrees cooler at load, Nothing special here. Only thing I have noticed is the 2016 takes more time to hit 5900rmp while the 2015 hits 6200rpm.

It feels warmer to the touch? Or how did you determine this.

You are BIG trouble maker

 

[MH01]

Yeah I initially thought that, but it's close, when it comes to temps the 2015 and 2016 are all but the same. No upgrade here

Notebookcheck reports in their review of the 15 MBP, that the 2.6 Ghz CPU stayed around 91 C during Cinebench. It then stands to reason that the 2.7 Ghz and especially the 2.9 GHz version likely run even hotter during more intensive tasks.
