MacBook Pro heating up when browsing Safari

Without doing anything special my MBP (13-inch, 2017, Touch Bar) starts heating up a lot when using Safari.

There are basically no programs running in the background that could possibly be the cause of this.

The most intensive task that I use Safari for is usually playing audio in the background (mostly from YouTube) when I'm in a different task (within the same desktop) doing research.

The fans never start to run faster than usual even though the bottom of the notebook is noticeably warm and almost uncomfortable to have it rest on my lap.

I have already heard that the never MBP have this issue where the fans set in much too late but this seems a little ridiculous.

What can I do about this? I don't always want to stop listening to music via a tab in Safari having YouTube opened, just so my battery won't die and the device won't heat up.

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.2), 13-inch, 2017, Space Grey

There are two common causes for what you observe:

1) Anti-virus, "cleaning" and some online banking secutrity software

2) poorly written, incompatible, or out-of date browser extensions or plug-ins.

You can post a snapshot of your software configuration that may reveal to us the issue. Fortunately there is a safe and secure way to do that.

A respected and long-serving member of these communities has created a simple utility that will take that "snapshot" of your configuration without revealing any sensitive information about you and your computer. It is Etrecheck, and is available here:

Run it and, when its report displays, click Etrecheck's "Share Report" icon and then "Copy Report" from the resulting dropdown. Paste the entire report into a response to your own thread here. It will often allow us to quickly identify or eliminate software as the problem.

In this Apple article:

Mac notebooks: Operating temperature - Apple Support

Apple states that a very warm case bottom is normal, and I agree:

The bottom of your Mac notebook may become very warm during normal use. If your notebook is on your lap and gets uncomfortably warm, move it to a stable work surface that allows for good ventilation.

That article also has information about blocked air vents and other issues that can make yout notebook run hotter.
