Why is VRM Cooling so important?

Everything installed on the motherboard matters and if you are a Gamer or PC enthusiast who loves to tinker with the motherboard then you might be knowing how important the VRMs are? But before looking into the advantages of VRM cooling let's just understand VRMs.

What is a VRM?

VRM stands for Voltage Regulator Module that regulates the voltage supplied to the CPU or GPU. CPUs generally require 1 to 1.3 volts to operate while the voltage delivered by the power supply is 12 Volts, which needs to be regulated accordingly. In easy words, VRM makes the power supply usable for our CPU and GPU so that it can deliver optimum performance.

Technically it is a Buck Converter(DC-to-DC step down power converter) circuit that contains Mosfet, Diode, Inductors(Choke, Cubical in shape), Capacitors(Cylindrical in shape), IC(Pulse Width Modulation controller), etc. 

VRM consists of various Power Phases which are basically Powerlines that are used by different parts of the CPU such as Cores and Integrated GPU. Multiple power phases divide the power load into different phases which result in reduced heat and stress on components. Also, more phases mean a reduction in the operating time of the On-Load power phase due to which it will be subjected to lower stress and heat. 

Note: More VRMs don't always mean better performance but it also depends upon the quality of the VRMs.

Why is VRM cooling necessary?

Since VRM supplies required power to the CPUs and GPUs, also their performance depends on the power supplied to them so it is necessary to keep them cool for optimal performance. Overheating of VRM will interfere with the power delivery which will result in a drop in gaming performance. 

Also, Overclocking(Pushing your system to higher limits) of the CPU requires more power(producing more heat) so high-quality VRM with sufficient cooling techniques only will serve the purpose. 

NOTE: Quality and Cooling of the VRM matter a lot in the Overclocking so it is always advised to go for a motherboard with high-grade or reliable VRM components.

How is VRM Cooling done?

VRM cooling is done by applying a thermal paste on the IC chip and then installing Heat Sink on the top. This will efficiently transfer the heat from chips to the heat sink which will eject the heat into the environment.
