Voltage manipulation is usually reserved for mid tier to higher end boards. Boards that are built around the H410 shouldn't be having the option. According to the manual, here
, the BIOS has an option forVcore Voltage Mode/CPU Vcore/Dynamic Vcore (DVID)/BCLK Adaptive Voltage/CPU Graphics Voltage (VAXG)/DRAM Voltage (CH A/B),
perhaps that will allow you to manipulate the voltage on your processor. As a side note, I don't think you're going to need to do an undervolt on the processor...come to think of it, the stock cooler is just a waste of material, better invest in a cheap aftermarket cooler like the one made by Vetroo V5(or cheaper).
