System identity

This ArsenalPC desktop pairs an AMD Ryzen 9 9900X twelve-core processor running at 4.4 GHz with an NVIDIA GeForce RTX 5070 graphics card equipped with 12 GB of GDDR7 memory. The platform targets enthusiasts who need high core counts and modern GPU features for gaming or content creation. Builders who require ECC memory or multi-socket support will not find those capabilities here.

Thermals and power

A 240 mm liquid cooler handles the CPU heat load while the 850 W power supply feeds the complete system. The combination is designed to sustain boost clocks during extended sessions without excessive acoustic output. Users planning heavy overclocking or dual-GPU configurations should verify headroom against their specific workload.

Storage and memory

The 4 TB NVMe solid-state drive provides the primary volume for the operating system and active projects, supplemented by a 2 TB SATA hard drive for bulk data. All four DDR5 memory slots are populated to reach 128 GB, leaving no free slots for future expansion. Buyers who anticipate needing more than 128 GB of RAM must replace the existing modules.

Questions about this item

How do I install the 240mm liquid cooler and what step is often missed?

The 240mm liquid cooler comes pre-installed on the Ryzen 9 9900X. The step often missed is connecting the pump header to the motherboard CPU_FAN socket so the BIOS can monitor pump speed.

What maintenance will the 240mm liquid cooler need later?

The 240mm liquid cooler is a sealed unit with no user-serviceable parts. No coolant refills are required. Only dust the radiator fins and check fan operation periodically.

What limit appears first during sustained loads on the Ryzen 9 9900X with this 240mm cooler?

The 240mm radiator surface area limits heat dissipation first. Under prolonged all-core workloads the CPU will hit its thermal ceiling before the 850W power supply or 12GB GDDR7 GPU memory become bottlenecks.
