+ | * If you want a component to **stay cool or keep heat**, you want it to be very low conductivity so that it is slowly losing heat to the ambient air and requires minimal energy to keep at temperature. Minimizing exposed surface area will slow heat loss, so using additional layers of low conductive materials will | ||
