Replacing Liquid Metal on an Asus Zephyrus G15's CPU
I’ve been using the Asus ROG Zephyrus G15 as my daily driver for a few years now. Laptops (gaming laptops especially) pack a lot of heat-generating components in a small and thin space, where the only airflow comes from the small blower fans in the system. In the case of the Zephyrus G15, there’s approximately 120 Watts of output, with 80W-100W going to the GPU and the rest going to the CPU.
I clean out the dust from the fans and heatsinks every few months (which you really should do, if you have a laptop), and the GPU wasn’t affected, so I suspected the liquid metal had shifted from its factory application. Trying to soak it up with paper towels didn’t work, and trying to wipe it away or scoop it out started tearing the silicone barrier, which covers up SMD components around the CPU die. Re-screw the heatsink in the order marked next to the screws, re-attach the wireless antennae, reconnect the battery, and we’re ready to boot up the laptop and check if everything is working properly.
