It has been confirmed that ASUS has used liquid metal rather than thermal grease on laptops with Ryzen 9 7945HX3D processors.
It is news that Uncle Tony, a Techtuber of Bilibili in China, disassembled the Asus ROG Strix Scar and checked the liquid metal. For this, it turned out that all parts except the CPU die were sealed.
Sealing treatment is an essential measure to use liquid metal, which is a conductive material. Various methods are used, but it is common to insulate parts other than the contact surface like ASUS.
In addition to the Ryzen 9 7945HX3D processor, it has been confirmed that ASUS applied liquid metal to the GeForce RTX 4090 GPU and insulated it in the same way.
Thanks to the use of liquid metal, a large vapor chamber, and heat pipes, the temperature of the hottest part of the Asus ROG Strix Scar was 56.6 degrees, and it was evaluated to effectively dissipate CPU and GPU heat.
