How to undervolt RX 470 in MSI Afterburner?

[Exodias3219]

Hi, I want to undervolt my MSI GAMINGX RX 470 since it's hitting 80-90C at stock configuration. Upon searching I found that undervolting will bring the temps down. But I can't find any guides on how to do it. I don't know if I should touch the "Core Voltage" or the "Power Limit". I have read that 1025mV should do the job but I don't know how to do it. I also replaced the thermal paste. Here is the article

Its better to use amd wattman, only con what was for me i had to manually save profile and then load it every time.

For guide google rx 470 undervolt and try to use those users settings, which worked for me.

For me it was 1050mV on core , and memory 975, also a bit agressive fan profile rx 480 btw.
