Image result for msi 1070 gaming x

 

What does PWM have to do with this heatsink?, I thought PWM was a thing on fans.

AFAIK, it cools the VRM components...

No, PWM is also a power delivery thing. This is covering the power delivery system.

AFAIK, PWM can be used to describe a way of distributing power as well...

They work exactly the same, that's why they have the same name...

PWM stands for Pulse Width Modulation. You can change the amplitude of something (usually a DC voltage)  by changing the pulse width of a digital periodic signal (the percentage of time it is 1 compared to the time it is 0). If the signal is always 1 then the output will be set to 100%, and if it is always 0 it will be 0%. If it is a square signal with 50% duty cycle then it will be 50%.

The PWM in a fan is a DC-DC voltage converter that take the 12v input and convert it into an output voltage whose value depends on the PWM signal.
The PWM in a Graphic card does about the same. It converts the input 12v into smaller voltages usable by the GPU.
