First off, I did not say it would do any better.
I'm just saying it's not going to have much effect and only if designed properly.
I'm not an expert in this field, but as far as I know, there are heat conductive pads that can possibly achieve this.
I do not have any empirical evidence or data to which how effective these stuff are, and would not want to rely on common sense to call off the idea.
Back to the topic, I wouldn't be getting one for $60 even if it improves cooling by a little bit anyway.
