I have been using my new 2017 ntb MBP (2.3 GHz i5, 16Gb RAM, 256Gb SSD) for about a week now, and I have temperature problem.

Currently running apps are safari (with 15 tabs), Adobe pdf reader (3 pdf tabs), power point (with about 40 slides), mail, message, itunes and evernote.

I don't normally sweat a lot, but my palms get sweaty when using this new MBP.
I did not have this problem with my old 2015 12" MB.

I downloaded this CoconutBattery, and it says the battery temperature is 37.5 degrees celsius (99.5 fahrenheit).

The fan does not turn on either. I kinda hoped to hear how loud the fan would sound.

At what temp does fan turn on?
Is my 2017 ntb MBP normal?

If you get MacsFanControl from https://www.crystalidea.com/macs-fan-control you can see all the temperature sensors for your device. You can also manually control what sensor is used for the fans and at what temperature the fans kick in.

I've been using this app for several years now on various devices after finding it while trying to determine an issue where my fans were never coming on (CPU temp above 110C).

This is my current temperatures. Note that I'm not doing anything taxing (other than installing the Xcode update from the App Store) my fan is currently at around 1200 rpm.

A lot of the time, my fan is a 0 rpm even though the CPU temperature is around 60C

Here's my experience. High temperatures and crazy fans. Also crazy when apparently not high temperatures.

Chrome is an evil browser in my opinion, but that is a religious war that will rage for a long time. My experience is that the company that owns the platform will try to make their browser run in a way that gives the best numbers for the platform whereas other browsers will make their browsers run in a way that gives the best numbers for the browser. So for me, in macOS it is Safari and in Windows it is Edge.

I get the issues with Safari too.

One question about the fan speed.
How can your fan is at 0 rpm when it's min speed is 1200rpm?

I don't hear my fan running however, on macs fan control says my fan is running at around 1800 rpm. Looks like it can never go to 0 rpm? ie. Fans running constantly at low rpm.

If I set the fan to a manual configuration it is always running, but if I have it set to auto a lot of the time the fan isn't doing anything (according to the app anyway). There's also no noise or airflow coming from the vents.

The fans on the MBP 13" normally are not on. One person is having a lot of problems but most people are not. When not running under a high load my fans are at 0. I use Monity from the App Store which runs as part of the notification panel.
