If the ambient temperature is high, the fans turn on sooner and run faster. Find out more about the operating temperature of Apple notebook computers.

Is there fan noise on my new iMac?
I’m experiencing some fan noise on my new 2019 iMac, and wanted to see if anyone else who’s purchased one of the new machines is having a similar issue. I have a CTO model, with 3.7 Intel Core i5, 8 gb ram, Radeon Pro 580x 8 gb, and a 500 gb SSD.
What’s the difference between 2017 and 2019 iMacs?
I remember one of the early Apple Insider video reviews (bas and i9 were both in it) saying the fans were slightly louder (and deeper sounding?) on the 2019s at 1200 RPM vs the 2017s. At higher loads the 2019s stayed quieter (more like 1800 RPM) where the 2017 i7 quickly went to max. I have the maxed out i9 and have ZERO fan noise.
What’s the fan speed on a MacBook Air?
In fact, when I check in Mac Fan Control the fan speed is hovering between 1195-1205 rpm, the lowest speed, and all the temps seem normal: 28 degrees ambient and between 35-40 for CPU and GPU. I want to know if anyone else who purchased a similar machine is also noticing this.
