First day with new M4 14", fan is loud

[kave]

After four years with a M1 Pro 16" MacBook Pro I thought I would downsize to a 14" M4 with 16GB Ram and 1TB SSD. I have just transferred all my data to a new 14" M4.
With four years of using the 16" I have never heard the fan, no matter, video export, Dropbox indexing etc.
Now with the 14" I am hearing the fan on and off all the time. I really hope this will end when all indexing is done otherwise I will return it.

I traded my 16"/M1 pro for this 14"/M4 pro and it is quiet, unless your running an LLM and editing videos.You're comparing the 14 inch chassis vs a 16 inch one. The fans on the 16 inch are bigger so they are able to spin slower while providing the same level of cooling (and also take longer to come on due to the chassis allowing for better passive cooling)
I just tried Endurance CPU and the fans never came on.
