How does it work?
It doesn't
Yeah, just googled it and was going to come back and post it.
Heat shield is a misnomer, it is a heatsink just a very poorly designed one. A heat shield is something that is designed to prevent thermal conduct, the name and marketing implies it's supposed to prevent heat from your gpu getting to the m.2 drive, it doesn't, it's not a heat shield by any description. It's a thermal pad and some metal, it has a little more surface area than the chips themselves because the chips don't span the entire sticks area, so it works marginally as a very poor heatsink for the top side. But it's blocking more airflow to the bottom side so increased temps.
Basically it's both a very poorly designed heatsink, and it's incredibly poorly marketed by mixing terminology which suggests to completely opposite technologies working together(heat transfer and thermal insulation).
It was like when ddr first got heat spreaders, at the time and probably still now just a complete waste of time. Due to the thickness of them they reduce air and effective surface area by making it far harder for air to get between sticks if you have them in adjacent slots.
