Macbook Pro 16" gets hot with simple tasks

Dear Apple fanatics,

At the moment I work a lot at home and use my Macbook Pro 16 " mainly with Microsoft Teams. My question is whether you also suffer from a high CPU temperature and a lot of fan noise.

My MacBook gets at least 70 degrees Celsius. I must also mention that I use a second screen.

I am familiar with disabling hardware acceleration through Teams, but this makes video calling practically impossible due to the 3 FPS in a call.

Thanks in advance for your help.

MacBook Pro 16″, macOS 11.0

FWIW, this is from a Google meet this evening:

CPU temp of 78 °C, fan at 1842 rpm (idle is 1500-2000 rpm). Having said that, after about 30 minutes the fans had sped up to ~2600 rpm (still not audible) which brought the temp down to 71-73 °C.

This was just on the internal display, having a second display would also add to GPU load and I could see that adding enough heat to ramp up the fans.

But one other point – the 3.48 (GHz) to the right of the fan speed is the CPU clock, and >2.3 GHz means TurboBoost is active. That can ramp up temps and thus fans pretty quickly. Some have reported that disabling TurboBoost results in reduced temps and fan speeds without a meaningful performance hit. It can be disabled with a 3rd party utility called TurboBoost Switcher.
