White Platinum chassis and Arrow Lake Ultra 9

The ASUS ROG Zephyrus G16 GU605CW-XS98 is a 16 inch gaming laptop finished in Platinum White. It ships with Windows 11 Pro and targets users who want a portable workstation with high-end graphics and memory. The Intel Core Ultra 9-285H processor has 16 cores and a 5.4 GHz maximum turbo frequency. An NVIDIA GeForce RTX 5080 GPU with 16 GB GDDR7 handles rendering workloads.

Gelid GC Extreme on GPU and Conductonaut on CPU

HIDevolution applies Gelid GC Extreme thermal compound to the GPU and Thermal Grizzly Conductonaut to the CPU during assembly. This custom thermal interface material upgrade is intended to lower component temperatures under load. The 240 Hz OLED panel runs at 2560 by 1600 resolution. Power draw and acoustic behaviour will follow the thermal headroom created by the upgraded TIM.

8 TB PCIe 4.0 NVMe and soldered 64 GB LPDDR5X

Storage is provided by an 8 TB M.2 PCIe 4.0 x4 NVMe SSD for fast boot and load times. System memory is 64 GB LPDDR5X 7467 dual channel soldered to the board. The chassis measures 13.94 by 9.69 by 0.59 to 0.65 inches and weighs 4.08 lbs. Ports and mounting points follow the standard Zephyrus G16 layout for daily docking and peripheral use.

Questions about this item

How is the thermal compound applied to the Intel Core Ultra 9-285H and RTX 5080 during the HIDevolution build process?

The CPU receives Thermal Grizzly Conductonaut liquid metal while the GPU gets Gelid GC Extreme paste; both are applied by hand during assembly before the heatsink is mounted, replacing the factory pads for lower sustained temperatures.

Which components can be replaced or upgraded after purchase without voiding the HIDevolution warranty?

Only the 8 TB M.2 PCIe 4.0 x4 NVMe SSD is socketed and user-replaceable; the 64 GB LPDDR5X 7467 memory is soldered to the board and the OLED panel is integrated, so neither can be swapped later.

What thermal limit appears first when the RTX 5080 runs at full load for extended periods?

The GPU hits its junction temperature ceiling before the CPU or VRMs, causing the fans to ramp to maximum and the core clocks to step down until the Gelid GC Extreme interface brings the die back under the throttle point.
