20-Core Liquid-Cooled Workstation

This business desktop pairs a 20-core Intel Core Ultra 7 265K processor with a 240 mm liquid cooler, 128 GB of DDR5 memory and an Nvidia RTX A400 graphics card. It ships with Windows 11 Pro 64-bit and is configured for professional workloads that demand sustained multi-threaded performance.

Upgrade From Air-Cooled Entry Workstations

The liquid cooling and 20-core CPU replace older air-cooled systems that throttle under continuous render, simulation or compile loads. The jump is worth it when projects exceed the thermal headroom of a standard tower and when 128 GB of memory removes the need for constant swap-file activity.

Suits AI-Ready Multi-Display Studios

Four Mini DisplayPort outputs drive multiple calibrated monitors for colour-critical pipelines, while Wi-Fi 7 and 2.5 Gb Ethernet keep asset transfers fast. Buyers who need ECC memory, dual-GPU compute or more than 192 GB of RAM capacity should look at a different platform.

Questions about this item

Will the Corsair 4000D case fit in a space measuring 490 mm deep, 239 mm wide and 486 mm high?

The chassis measures 490 mm deep, 239 mm wide and 486 mm high, so it needs at least that much clearance plus room for rear cables and top radiator airflow.

What is the correct orientation for the 240 mm liquid cooler radiator and fans during installation?

Mount the radiator at the top or front with tubes at the bottom of the loop and set fans to exhaust hot air out of the case.

When should the 140 mm PSU fan and the 240 mm radiator fans be cleaned or replaced?

Clean dust from both fan sets every 6 to 12 months; replace any fan that develops bearing noise or reduced airflow.
