I have one with metal plate, but since I have to limited edition. I want to keep the look. I am sure it will help a lot with heat distribution. Let me know if you try it.

I did put thin tape on the bottom. Just to be in safe side. Don’t want SSD to short out. As far as the APU temp goes, I played 3 hours of starfield and didn’t notice any higher fan noise or temperature. The metal heat shield valve put in the new oled model don’t have any thermal pads on it so I don’t think it’s there for any heat distribution. I think if there are any issues only long term use will tell.
