What would be ideal is if we had sheet metal, a layer of foam, then another layer of sheet metal, basically sandwiching the foam. You'd have flippen thick covers though
no jokes i installed spot cooler for the gpu coz i thought 69 celsius was hot but the gpu just switched the fan off when temps
were below 60 celsius , now they are sitting at 54 celcius with just the spot cooler the gpu's fan is always at 0% now .
