System identity

This ArsenalPC desktop pairs a 12-core Ryzen 9 9900X processor running at 4.4GHz with an NVIDIA RTX 5090 graphics card equipped with 32GB of GDDR7 memory. The platform delivers 128GB of DDR5 RAM and a 4TB NVMe SSD for professionals and enthusiasts who need maximum compute and graphics throughput in a single workstation.

Thermals and power

A 240mm liquid cooler manages CPU heat while the 1200W power supply feeds the complete system. Integrated 2.5G Ethernet and wireless connectivity handle network traffic without adding acoustic load. The MSI GUNGNIR 110R chassis uses RGB lighting for visual feedback rather than aggressive fan curves during typical workloads.

Sustained load behaviour

Under continuous heavy compute or rendering tasks the liquid loop maintains stable temperatures for the 12-core processor and the high-memory GPU. The 1200W unit provides headroom for prolonged maximum-frequency operation across both CPU and graphics silicon without throttling. Windows 11 Home runs on the 4TB NVMe drive, keeping the OS responsive during extended sessions.

Questions about this item

How do I install the 240mm liquid cooler in the MSI GUNGNIR 110R case, and what step do people often get wrong?

The 240mm liquid cooler ships pre-installed on the Ryzen 9 9900X; the step people miss is checking that the radiator fans are oriented as intake at the front of the 110R so the 1200W PSU airflow is not restricted.

What maintenance or replacement will the 240mm liquid cooler and 128GB DDR5 memory need later?

The sealed 240mm liquid cooler requires no refill; dust the radiator fins every few months. The 128GB DDR5 288-pin DIMMs are non-ECC consumer modules and have no scheduled replacement.

What limit shows up first under sustained use with the RTX 5090 32GB GDDR7 and Ryzen 9 9900X?

The 240mm liquid cooler’s thermal capacity is the first limit; prolonged 12-core 4.4GHz loads plus the 32GB GDDR7 GPU can saturate the radiator, causing clock throttling before the 1200W PSU or 4TB NVMe SSD hit any ceiling.
