ROG will be using liquid metal for all their 10th Gen Intel Core laptops
We all know that liquid metal offers much better thermal conductivity than thermal paste, but the application is definitely a lot more complicated. Even for one-off applications for my personal rigs, I am quite reluctant to apply liquid metal. But ASUS ROG has found a way to automate the process to apply liquid metal and roll it out across their 2020 lineup of Intel laptops featuring the 10th Gen Intel Core processors.
ROG R&D engineers selected Thermal Grizzly’s Conductonaut for its optimal properties and designed the machine to apply it. The machine consists of a mechanical arm that wets its silicon brush in liquid metal before proceeding to “paint” the CPU die. It does exactly 17 passes, a number which was found by the engineering team to be the ideal number for optimal coverage.
To minimize the accumulation on the edges of the processor, the brush makes contact at different points on the surface with each subsequent stroke. The die is also set into a stainless steel shim to prevent excess compound from spreading to the surrounding areas. After the initial brushing of liquid metal, a second machine injects more compound at two points on the die to ensure that there’s sufficient liquid metal for proper contact between the cooling plate and the CPU die. And to prevent any mishaps with the liquid metal seeping out and shorting out nearby components, ROG engineers designed a special barrier fitted between the heatsink. The process of applying liquid metal and the barrier are patented, recognizing the innovation that ROG is continually bringing to the gaming laptop industry.
The first “laptop” that featured liquid metal in ROG’s lineup is the ROG Mothership, and it proved really effective. ROG engineers has observed a 10-20°C reduction in temperatures depending on the CPU with the use of liquid metal. This should allow the latest 10th Gen Intel Core processors to deliver better performance via Intel Thermal Velocity Boost, as the technology relies on having thermal headroom to boost higher and maintain the clocks until it hits certain thermal thresholds.
Pokdepinion: Gotta hand it to ROG for paying so much attention just to get extra performance out of their laptops.
