batterycpumacbook protemperature
I just got a new MacBook Pro 2017 128GB no-touchbar, bought it in the refurb.
I'm doing a bit of Photoshop ( I know it's not the best MBP, but I really need it right now for work ) and I have Safari ( 6/7 tabs ) running with Spotify, and I feel like my MBP is too hot. Here are the temperatures according to iStats
I feel like it's really way too hot, but perhaps I'm mistaking. I heard the max temperature is 100°C, so I'm pretty far from that.
What do you think ?
Thanks !
What you are experiencing is quite normal for MBP. It may vary quite a lot with an ambient temperature above 28 degrees C. The only inconvenience with the high speed of the fan is the noise. Rather than that, you can keep it faster and the MBP will be cooler. Obviously also the fan life will be slightely reduced but they are so performing that most probably you will not see the end of the fan life. Another trick is to make sure the MBP is placed on a surface that can dissipate temperature. A wooden table or a glass table as well as your legs are not the best heat dissipators.
I understand your concerns (justified or not), you love your Mac and want to keep it alive as long as possible.
Here are some home remedy (Do it Yourself)-- (also available where you live).
If you want to keep your Mac cooler during HOT games, go to pharmacy and buy what they call a gel-pack (gel balení). Freeze it!
Then put it under your Mac with a towel in between (to prevent freezing).
That will provide additional cooling for few hours. Have second gel-pack if you want to continue gaming for 24 hours a day :)
As for your temperature reports, so far they look normal based on this example.
Throttling
This test wouldn't be complete if we didn't address the subject of throttling. Prime 95 and Furmark can extract the maximum performance out of the hardware. When both programs are run simultaneously, the core frequency drops (caused by Prime 95) to 1.2 Ghz. Running Prime 95 alone, we measured temperatures between 92 and 104 degrees Celsius (197.6 and 219.2 degrees Fahrenheit), and the word "Throttling" flashes repeatedly in HWiNFO. Furmark on its own cycles through all available Turbo Boost steps. After about one hour, the temperature settled at a fairly consistent 85 degrees Celsius (185 degrees Fahrenheit) with the fan system running. We never measured above 100 degrees Celsius (212 degrees Fahrenheit) with Furmark. This limitation might be due to the power adapter: in the above scenario, the system would require 86.6 watts - but the power adapter can only supply a maximum of 85 watts. Immediately after running our different tests, we subjected the system to 3DMark 06 and CineBench R11.5. The results were identical to after a cold boot.
The fastest way to quick check is to use the surface temperatures as shown here.

Totally normal if on the low side. If your CPU is less than 15% idle, I expect you to get to 85 C internal for CPU proximity and higher for all the on die thermocouples. Running just unde 100 C is how the silicon is designed to operate at max thermal generation and high sustained load.
Also, if you use the command line tool to check temperatures or thermal load once every 15 minutes instead of having graphs checking every second you may find your CPU runs much cooler. After all, having those graphs update live in real time prevents the CPU from sleeping.
Lots of people are surprised or at least concerned by temps:
From an engineering standpoint, the MacBook Pro and the iMac in the Mac Pro and iMac Pro all have the same power envelope design and push their CPU to 100 C when the work is available. Once the CPU is at Max normal operating load then the kernel task begins to idle potential work so as not to exceed the final design for the processor.
