ASROCK APPS
There are two main bits of software you should download from ASRock, the Polychrome Sync and A-Tuning.
As the name suggest the Polychrome Sync software allows you to control the RGB/ARGB LEDs of both the motherboard and the attached peripherals/hardware (just as long as they support it).
On the other hand, the A-Tuning software basically simplifies overclocking so you can either choose one of the three modes (there’s also a power saving mode here) or tweak the CPU manually.
This software also has a CPU info tab from where you can monitor its temperatures and voltages and a FAN-tastic tab from where you can again adjust fan curves.
