Purpose-built desktop

The Velztorm Pilum is a pre-assembled gaming desktop built around an AMD Ryzen 7 3700X eight-core processor running at 3.6 GHz with a 4.4 GHz boost. It ships with 64 GB of DDR4 memory, a 1 TB PCIe NVMe solid-state drive plus a 6 TB 3.5-inch hard drive, and an AMD Radeon RX 6900 XT graphics card equipped with 16 GB of GDDR6 memory. The system targets enthusiasts who want a ready-to-game Windows 10 Pro machine without selecting individual parts.

Thermals and power

A 120 mm all-in-one liquid cooler handles CPU heat while RGB fans move air through the black chassis. The 750 W power supply feeds the processor, graphics card, memory and both storage drives under typical gaming loads. Wireless connectivity uses 802.11n; Bluetooth is not included, so users needing wireless peripherals must add a separate adapter.

Bundled experience

Windows 10 Pro is pre-installed and activated, removing the need for a separate licence purchase. The rear I/O panel provides USB 3.1 Gen1, five USB 3.0 Type-A ports, four USB 2.0 ports, one USB 3.1 Type-C Gen1 port, HDMI, DisplayPort, microphone and headphone jacks. Buyers who require Bluetooth, a different Wi-Fi standard or a larger all-in-one cooler will need to source those upgrades themselves.

Questions about this item

How do I install the 120mm AIO liquid cooler on the Ryzen 7 3700X, and what step is often missed?

Mount the radiator with tubes at the bottom, apply thermal paste evenly on the CPU heat spreader, secure the pump block using the AM4 bracket, then connect the pump header and fan cable to the motherboard — the step most often missed is removing the protective plastic film from the cold plate before mounting.

What maintenance or replacement will the 120mm AIO liquid cooler and 750W power supply need later?

The AIO is a sealed unit requiring no coolant refills; plan to clean radiator fins and replace fans every few years if noise rises, while the 750W PSU may need replacement after five to seven years as capacitors age under sustained gaming loads.

What limit appears first during sustained heavy gaming on the Radeon RX 6900 XT with the 120mm AIO cooling the Ryzen 7 3700X?

The 120mm radiator reaches thermal saturation before the GPU hits its power ceiling, causing CPU clock speeds to drop below the 4.4 GHz boost as coolant temperature rises, which throttles the 8-core processor during extended sessions.
