How to make fans stop working so much?

I am still working on this issue...

What was done so far:

- SMC reset

- System reinstall (high sierra)

- Hardware test at an authorized store (not apple) - even the girl from there could not believe that such machine has to use the fans at full throttle with youtube videos.

Maybe the mac cannot handle too many scripts running.After investigating a bit seems like the system will assign each available core to handle each chrome tab:

How can we avoid this? Or how can we configure/adjust chrome settings?

Am I the only one with this issue?

and normally when looking at the activity monitor, the process using more cpu is the kernel_task.

I am running out of options

35C when booting and fans working normally at 2156 rpm

Opened 5 youtube video tabs playing the videos, and went up to 70 C and fans are at 5804 rpm

Is it true that the system will assign each chrome tab to each cpu core available? does that maybe make it too hot?

with safari things are better...

As soon I start chrome it start to warm up very much, and btw, every chrome extension will count as a process for the CPU... also detected that onedrive for mac also makes it warm too much.

I have to find a solution to have chrome back; I am used to it, it is faster, I can translate any page with right click, login with my gmail account, sync all my stuff between different machines and all that chrome offers.

I open the 5 to make the fans work...

repeated these SNTS Boiler Room Berlin Live Set - YouTube

I use chrome because Ive always used and have all my setup there - I will try safari

Thanks a lot tjk

I will make the switch to safari these days.

Ive read somewhere that chrome tabs will use as many cores available as the cpu has. maybe it is true..

I think I solved the issue .. by downgrading to Sierra.

Everything went back to normal. I am now using chrome as daily browser
