18-inch UHD+ Mini LED mobile workstation

The MSI Raider 18 HX AI A2XWJG-841US is an 18-inch gaming laptop built around a 3840 x 2400 120Hz Mini LED panel. It targets professionals and enthusiasts who need desktop-class compute and graphics in a single chassis. The system ships with Windows 11 Home and a Core Black finish.

Gelid GC Extreme thermal upgrade over stock

HIDevolution replaces the factory thermal interface material with Gelid GC Extreme on the CPU and GPU. The modification lowers sustained temperatures and reduces throttling during extended compute or rendering workloads. The jump is worth it when sessions run long enough for heat to saturate the stock solution.

24-core Ultra 9 285HX with RTX 5090 under load

The 24-core Intel Core Ultra 9 285HX reaches a 5.5 GHz max turbo frequency alongside the NVIDIA GeForce RTX 5090 Laptop GPU with 24 GB GDDR7. Dual-channel DDR5 5600 memory and 16 TB of PCIe 4.0 NVMe storage keep data flowing during prolonged heavy use. The 7.94 lb chassis dissipates heat across a 15.91 x 12.09 x 1.26 inch frame.

Questions about this item

What chassis clearance does the 15.91" x 12.09" x 1.26" frame need inside a backpack or sleeve?

The laptop measures 15.91 inches wide, 12.09 inches deep and 1.26 inches thick, so choose a sleeve or compartment rated for at least an 18-inch class device with a little extra depth for the power brick.

Which screws and clips must be removed to reach the two M.2 slots holding the 16 TB of storage?

Remove all bottom-case screws, then gently pry the panel starting at the front edge; the two M.2 4.0 x4 slots sit side-by-side under a single thermal pad — lift the pad once, swap drives, then reseat the pad before closing.

When should the Gelid GC Extreme compound on the CPU and GPU be reapplied?

Re-paste with Gelid GC Extreme if sustained core temperatures climb more than 10 °C above your baseline after a year of heavy loads, or whenever the heatsink is removed for a fan cleaning or SSD upgrade.
