Using liquid metal to dissipate heat, Asus laptops will be 10 to 20 degrees cooler than usual

Asus says it will switch to using liquid metal to replace the usual thermal paste on its laptops. This is to address the enormous amount of heat emitted from today’s laptop CPUs.

This is a problem not only for Intel processors but also for products from rival AMD. Even AMD’s top 7nm laptop CPU, Ryzen 4900 HS can make the casing of Asus ROG G14 reach 51oC and CPU temperature up to nearly 80oC.

This temperature will certainly be even higher on Intel’s H-series Comet Lake CPUs introduced last week. With a maximum clock speed of up to 5.3 GHz and 8 CPU cores, the heat generated by these processors will certainly not be smaller than its competitors.

That’s why Asus partnered with Thermal-Grizzly and will use Conductonaut liquid metal thermal paste on their upcoming laptops. Conductonaut is made of a mixture of tin, Indium and Gallium with thermal conductivity of 73W / mK – 4 times higher than conventional thermal paste.

For those looking to buy a new laptop, of course they will benefit from this new type of heat sink. But for enthusiasts who love to remove their laptop and re-apply thermal paste to improve cooling, the new heat sink can cause problems.

Conductonaut contains Gallium, a substance that can destroy aluminum and be toxic if exposed directly through the skin. Therefore, if you put a little of this liquid on the motherboard, the laptop may be damaged when the Gallium in the heat sink destroys the aluminum material on it.

That’s why Asus has developed a process that uses the machine to bring this heat sink to the CPU casing, as you can see in the video below.

Though quite complicated, it is well worth it. Asus says switching to liquid metal heatsinks will help reduce CPU temperatures by 10 to 20oC, greatly improved other factors, including fan noise level as well as laptop battery life. However, a bit unfortunate is that this type of heat sink is currently only used for Intel laptops.

This will surely be a very welcome improvement users in the future. As the process of narrowing down the processor process becomes more and more difficult, companies are choosing different ways to optimize other factors that affect computer performance.
