Fan runs loudly without stopping and drains battery rapidly.
I am using a Macbook pro (Core i5) with Sonoma 14.4.1. Recently, my fan has started running loudly. I thought it was OneDrive but when I look at CPU usage, nothing significant is taking place (sometimes OneDrive and Kernel but not often). As I type this, my fan is making a noise but my computer is 79% idling. Even when I close my computer and it goes to sleep, the fan continues sometimes. It uses up my battery within two hours if it is running and the only way I can make it stop is by turning the computer off. I have run diagnostics and nothing comes up and I've done a reset of the SMC and this did not help. Nothing seems to be working. The only time it does not run liudly is if I am not connected to the internet. Please can someone assist. I can't keep up with this short battery life.
