Fan speed ramps up when system goes into standby/screenblank (Desktop)

My arch linux installation is about a month old(I'm new, still configuring my setup).
Since the beginning, whenever the screen blanked due to inactivity, the CPU fans would ramp up and stay that way. Not max speed but a constant high speed. It will stay this way for hours until I move my mouse/press a key on my keyboard to resume activity. When I do this, there is instant ramp down of the fan speed.
I don't remember configuring/trying to configure ANY power management settings.
The only thing that comes to mind which is even remotely related to power management is the swap I set up during installation. Otherwise, it was just a regular installation.

I am not sure how to go about troubleshooting this problem.
I ran

systemctl list-unit-files | grep enabled

to check for any enabled power management services.
Here is the output of that:
