Built for creators and gamers

The ASUS ROG Zephyrus G16 GU605CW combines a 16-core Intel Core Ultra 9-285H processor with an NVIDIA GeForce RTX 5080 GPU carrying 16 GB GDDR7 memory. A 16.0-inch 2.5K OLED panel running at 240 Hz delivers sharp motion for competitive play and colour-critical work. Windows 11 Home ships pre-installed on 8 TB of PCIe 4.0 NVMe storage.

Thermal and storage upgrades applied

HIDevolution replaces the stock CPU compound with Thermal Grizzly Conductonaut and applies Gelid GC Extreme on the GPU for lower sustained temperatures. Two 4 TB M.2 PCIe 4.0 x4 NVMe SSDs are installed at the factory, doubling the original capacity. The 32 GB LPDDR5X 7467 dual-channel memory is soldered on board and cannot be expanded.

Limits of the platform

The laptop measures 13.94 x 9.69 inches and ranges from .59 to .65 inches thick, weighing 4.08 lbs. Its thin chassis restricts long-duration turbo clocks despite the upgraded thermal interface material. On-board LPDDR5X fixes the memory at 32 GB with no upgrade path. The PCIe 4.0 interface caps sequential SSD throughput below newer PCIe 5.0 drives.

Questions about this item

Will the LPDDR5X memory or the 8 TB NVMe storage need replacement later?

The 32 GB LPDDR5X memory is soldered to the board and cannot be replaced, while the two 4 TB NVMe drives occupy both M.2 slots and can be swapped for larger modules when needed.

Which limit appears first during sustained loads — the 5.4 GHz turbo ceiling or the thermal envelope of the 0.59–0.65" chassis?

The thin chassis and shared vapor chamber mean the thermal envelope is reached before the 5.4 GHz turbo can be held across all 16 cores, so temperatures throttle the CPU first.

How loud do the fans get and how hot does the Eclipse Gray surface become when the RTX 5080 runs all day?

Under continuous load the dual fans spin up to an audible but not intrusive level, while the keyboard deck and bottom panel grow warm to the touch as the Gelid GC Extreme and Conductonaut TIMs move heat into the thin magnesium-aluminium shell.
