If you really cared you could get fanless PCs. A few of the Surface Pro models have been fanless. I had a gorgeous fanless Xiaomi Mi book that had virtually no branding. Basically any fanless PC post SSD introduction are just as silent. From what I've heard some of Apple's newer MBPs with fans can get noisy under load too, particularly the 14".
I wouldn't call my ThinkPad P14s AMD gen whatever loud either. The fan will spin up when multiple cores are under heavy load but compared to the 2018 MBP it replaced it's essentially silent.
You can make a pretty silent desktop (more space for heat pipes and large cooling blocks). But I had a Lenovo laptop that was recommended during a Linux excursion and it was loud as well, getting the M1 Air after that was bliss.
