I have a Windows laptop for the first time in well over a decade for a project I am working on. Even though it is overpowered (i7, 64gb ram), and it is currently "idle", the cooling fans are working overtime because the damn OS is always busy doing some random shit when "idle". This is AFTER I ran a debloat script. It was near impossible to use before then.
EDIT: I found the cause of the fanning issue and different behavior between Win 11 and Linux (Pop!_OS). Even though the laptop comes with an Nvidia RTX 4000 series GPU, Windows 11 set the global default GPU to be the integrated graphics (Intel UHD). The same laptop under Pop!_OS automatically set the default GPU to Nvidia. As soon as I dug this up and switched the settings to Nvidia, the laptop stopped fanning full speed nonstop.
