Raider 18 HX AI A2XWJG-841US

This 18-inch gaming laptop pairs an Intel Core Ultra 9-285HX 24-core processor with an NVIDIA GeForce RTX 5090 Laptop GPU carrying 24 GB GDDR7 memory. The 120 Hz UHD+ Mini LED panel delivers 3840 x 2400 resolution for detailed visuals. It ships with Windows 11 Home installed.

Gelid GC Extreme thermal compound

The builder applies Gelid GC Extreme thermal interface material to both the CPU and GPU, replacing the stock paste to lower peak temperatures under sustained load. This change reduces the likelihood of thermal throttling during extended gaming or rendering sessions, helping the hardware maintain higher clocks for longer periods.

96 GB DDR5 5600 MHz and 4 TB NVMe Gen4 storage

Dual-channel 96 GB memory (2 x 48 GB) provides headroom for large datasets, virtual machines, and heavy multitasking without paging. The 4 TB PCIe 4.0 x4 NVMe array (2 x 2 TB) offers fast boot and load times for sizable game libraries and project files; capacity limits appear only when workloads exceed the installed 96 GB RAM or the 4 TB volume.

Questions about this item

How often should the Gelid GC Extreme thermal interface material on the CPU and GPU be checked or reapplied?

The Gelid GC Extreme TIM applied during the build-to-order process is a long-life compound; under normal gaming or workstation loads it typically does not need replacement for several years.

Which component hits its thermal or power ceiling first during extended all-core and GPU load?

The 24-core Ultra 9-285HX and RTX 5090 share a vapor-chamber cooler; sustained 5.5 GHz turbo on all P-cores usually triggers CPU power limiting before the GPU reaches its 24 GB GDDR7 thermal threshold.

What are the typical fan noise levels and surface temperatures when the system runs at full load for hours?

Under continuous load the dual-fan cooler keeps keyboard-deck temperatures in the low-40 °C range while fan noise settles around 48–50 dBA, a level comparable to other 18-inch desktop-replacement laptops.
