What is the normal temperature for Macbook Pro 13" early 2015?

Question

macbook

Bought my first Macbook Pro. Namely, the Macbook Pro 13 "early 2015 model.
And I did not expect it to get so hot.

For example, Skype, safari (12 tabs), opera (2 windows with 10 tabs each) are just open and the temperature of the processor is already 80C-90C with the fans on 3k rpm. Installed the Temperature Gauge Pro program. It turns on the fans automatically. But the laptop is still hot, the keyboard and case are 45 degrees.

Very strong heats the computer Opera, Skype, Photoshop..
I rendered a 3D image in Photoshop, so the processor warmed up to 105C with the fans on at 5k rpm.

How to understand the upper limit of normal temperature under the most stressful conditions and less stressful?

Answer 1

So how to determine the normal temperature of the processor? If we just turn on the laptop and do not open anything. What should be the idle temperature?
Macs fan control shows cpu peci (this setting heats up the most) when turned on at about 45 degrees. I open a safari, the temperature soars to 70. At the same time, the tabs are not open in the safari itself. Of the extensions, there is AdGuard. Then the cooler speed rises and the temperature drops. But I don't use Safari. I prefer chrome.
So in chrome, with 4 tabs open (not video), the temperature does not rise above 45. Fan speed 1200-1400. Enabled the mode in which they rise when they reach 55 degrees on the cpu peci.
When you open YouTube and 4-5 tabs with videos (1080p), the temperature rises to 60-70 degrees, the speed is 1700-2500.
And once the laptop for some reason hung when opening the video. I had to use the "hot" buttons to reboot. Why hung and did not understand. There were no error messages after switching on.
The whole thing happens when the laptop is on its knees. From the battery, the charge was about 25%.
I just replaced the thermal paste yesterday (for the first time since purchase). Maybe I applied it incorrectly ... although I did it the old fashioned way - a thin layer on the entire surface of the processor. Thermal grease arctic cool mx-4.
Thank you.

Answer 3

In general, I assume that the temperature is affected by the air being blown by the propellers. All the situations described above were done on the knees. It turns out that the poppy is not suitable for serious graphics tasks when working on your knees or you need to endure a hot case and keyboard.
Most importantly, I need to understand if a macbook is ruining a hot processor?
Do I need to adjust the propellers in such a way that when the temperature rises above 65, it turns on the speed by 60-70%?
