Built for heavy multitasking and 4K play

The Velztorm Pilum pairs an 8-core Ryzen 7 3700X with 128GB DDR4 and a Radeon RX 6900 XT carrying 16GB GDDR6. Storage combines a 512GB NVMe drive with a 6TB HDD. Windows 10 Pro ships pre-installed on a system powered by a 750W supply and connected through 802.11n Wi-Fi and wired LAN.

Thermals noise and power at idle

A 120mm AIO liquid CPU cooler handles the processor while RGB fans move air through the black chassis. At desktop loads the cooling loop runs quietly and the 750W unit draws only what the components need. No optical drive or Bluetooth hardware adds to the acoustic profile.

Behaviour under sustained load

During extended gaming or render sessions the AIO keeps the 3700X near its 4.4 GHz boost ceiling without thermal throttling. The RX 6900 XT maintains DirectX 12 Ultimate workloads with AMD FreeSync and Radeon Anti-lag active. Power delivery remains stable from the 750W source throughout long runs.

Questions about this item

How is the 120mm AIO liquid CPU cooler installed and which step is often missed?

The 120mm AIO arrives pre-filled and mounted on the Ryzen 7 3700X; the step users skip is connecting the pump header to the motherboard CPU_FAN connector so the pump runs at full speed.

What maintenance or replacement will the 120mm AIO liquid CPU cooler need later?

The sealed 120mm AIO requires no refill; after several years the pump may wear or the radiator fins clog with dust, at which point the whole unit is replaced.

What limit appears first on the Radeon RX 6900 XT 16GB GDDR6 during sustained gaming?

The GPU core temperature rises until the card hits its thermal throttle point, causing clock speeds to drop before the 750W power supply reaches its limit.
