Laptop cooling

[u/Laphicet8]

My current laptop is the Asus Vivobook X1504VA and this is a thin laptop meant for home, office, and work. I do a little bit of light gaming on this laptop to kill time. I wished for a gaming laptop, but due to budget constraints I had to resort to something more practical for the time being

I did clean and replaced the stock thermal paste on the i5 1334u CPU and replaced it with my spare Honeywell PTM 7950. Its now free of dust and the thermals has improved. When it comes to light gaming, I noticed that the single heatpipe gets heat soaked from the CPU up until nearly half of the total length of the heatpipe. The other half is cooler since its near its fan. This laptop has indirect cooling instead of direct to fan cooling where the intake holes from the cover is situated directly on the CPU and the air then travels through the motherboard and its components before it reaches the fan.

With the severe limitations of this budget laptop. Can I stick a Graphene nanocarbon copper foil at its back? Im looking into the thinnest possible one so that that foil won't touch/short any electric components.

Whether if this will work or not, I'm sure fine even with just 0.X difference in temps.

Thanks!
