Liquid-cooled Ryzen 9 workstation

This desktop pairs a 12-core Ryzen 9 9900X3D processor with a 240 mm liquid cooler and 128 GB of DDR5 memory. The configuration targets professionals who need sustained multi-threaded performance for rendering, compilation or AI workloads. A 1 TB NVMe drive and RTX 5070 graphics complete the platform for content creation and gaming.

Factory-fitted cooler and storage

The 240 mm quiet-edition AIO cooler is installed and tested before shipment, removing the need for manual mounting or thermal paste application. The Samsung 990 PRO SSD arrives as the primary boot drive with sequential reads up to 7450 MB/s and writes up to 6900 MB/s. Windows 11 Pro is pre-activated on the drive.

PCIe 4.0 and AM5 platform limits

The motherboard provides PCI Express 4.0 lanes for the graphics card and M.2 slots, capping SSD throughput at the 4.0 specification. The AM5 socket supports up to 192 GB of DDR5 across four slots, leaving headroom beyond the installed 128 GB. Rear I/O includes USB4 at 40 Gbps, 10 Gbps and 5 Gbps ports, plus Intel 2.5 Gb Ethernet and Wi-Fi 7 connectivity.

Questions about this item

Will the 240 mm liquid cooler need coolant replacement or pump service later?

The 240 mm Quiet Edition AIO is a sealed unit; no coolant top-up or pump maintenance is required during normal use.

What limits the RTX 5070 12 GB during long rendering sessions?

The 12 GB frame buffer fills first on large scenes, forcing texture streaming over the PCI Express x16 link.

How loud and hot does the system get when the 850 W PSU runs at full load all day?

The 140 mm front fans and 240 mm radiator keep CPU and GPU temperatures steady while the PSU fan stays near its ultra-quiet profile.
