What should be the thermal conductivity of the thermal paste?

[Pranam]

I am having Dell Inspiron 3521. The laptop ideal temperature is around 55C. So I thought of applying thermal paste on the CPU as well GPU.

Hence, What should be the thermal conductivity of the thermal paste?

and can you tell me what is the difference between Cooler Master, Master Gel and Thermal Grease difference?

Thanks in advance.

The higher is better. Though thermal paste will reduce couple of degrees at most.
The most commonly available, relatively cheap and good performing, would be Arctic MX-4

Thermal conductivity has units of W/m-K which reads Watts per Meter-Kelvin.
In 2018 some e-zine was testing top pastes and best had conductivity of 9 W/m-K.
I see some frequently purchased chinese pastes has conductivity of like 1.5W/m-K and people who bought it not reported they burned their CPU/GPU. When i go to a big e-shop i found most products are in category 7-8 W/m-K. There is even 4 products in category 12.5 W/m-K but these cost apparently more than 20USD per a few grams..

i'm surprised no one has come out with a carbon fiber cooler - i work with it and we are always amazed at it's ability to accept heat from one surface and dissipate it into the atmosphere- i mean seriously it conducts heat almost like copper conducts electricity

there is no need to bump 2 years old solved thread.

cheap carbon fiber has lower thermal conductivity than aluminum. a good performing (better than copper) carbon fiber is both much more expensive and have other shortages like high fragility.
