Stop overheating in computers by stacking copper coins on it

It’s always a problem of an uncomfortably hot computer – when you’re in the middle of a 3-hour usage, and suddenly the fan kicks into high-gear and your laptop starts burning into your legs. 
But with the help of thermodynamics, a Japanese twitter user
has come up with the ultimate and simple solution to the problem:
simply stack copper coins on top of your machine to cool it down.
Right now, you’re either sitting there bowing down to the genius
we’ve just gifted your life, or are wondering how the hell we hadn’t
already figured that out, and in the case of the latter, bravo to you.
You’re officially better than us at applying chemistry to the
requirements of modern computing.
But for those of you in that first group, this is how it works –
as Japanese site IT media found out back in 2012, the Macbook Pro with
Retina Display can run pretty hot when it’s working at the limits of its
Using thermodynamic scanning, they were able to show that the
heat is focussed towards the back of the computer, which you’ve probably
felt yourself (temperatures below in degrees Celsius): 
Japanese Twitter user akinori_suzuki decided to start stacking 10-yen coins, which are primarily made out of copper, on top of his laptop. It’s pretty brilliant, seeing as copper has much greater thermal
conductivity than aluminium or plastic – which most laptops are made out
of. Because of the laws of thermodynamics, this means that, as long as
the copper coins are cooler than your computer, they’ll ‘soak up’ the heat that would otherwise be causing issues for your central processing unit.

Twitter users sharing images of their own setups – and it turns out it’s
not just for laptops, it can also cool down your desktop tower:  
This is an unproven idea from the internet – the results haven’t been
tested in a proper, peer-reviewed experiment, and there’s no guarantee
that this is going to work for everyone. But the response online
suggests it’s pretty successful for a lot of computer lovers out there.
And for those of you feeling upset that you’re not living in Japan – the land of the copper coin.
We’re totally trying this one at home.
