24-Core i9 Workstation with Liquid Cooling

This desktop combines a 24-core Intel Core i9-14900K processor with 64GB of DDR5 memory and a 360mm liquid cooler in a Corsair 4000D tower. It targets professionals and enthusiasts who need high multi-threaded performance for rendering, compilation or heavy multitasking without building the system themselves.

Thermals, Noise and Power Draw

The 360mm Quiet Edition AIO cooler handles the 14900K heat output while the 140mm PSU fan runs at low noise levels. An 850W 80 PLUS Bronze power supply with Japanese main capacitors delivers stable power with Over Voltage, Under Voltage, Over Power and Short Circuit protection for the CPU, dual SSDs, 10TB hard drive and integrated graphics.

Bundled Storage and Connectivity Extras

Two 4TB Samsung 990 PRO PCIe 4.0x4 SSDs provide up to 7450 MB/s reads and 6900 MB/s writes for the operating system and active projects. The 10TB hard drive adds 256MB cache bulk storage. Wi-Fi 6 and BLUETOOTH 5.2 join Intel 2.5Gb Ethernet, while the motherboard rear I/O adds USB 3.2 Gen 2 Type-C, four USB 3.2 Gen 1, four USB 2.0 and internal headers for front-panel Type-C and additional USB ports.

Questions about this item

How do I install the 360mm Quiet Edition liquid cooler in the Corsair 4000D case, and which step is often missed?

Mount the radiator to the top panel using the included brackets, then connect the pump header to the CPU_FAN connector on the Z790 PRIME motherboard — forgetting the pump header leaves the cooler without power.

What maintenance will the 360mm liquid cooler and 850W PSU need over time?

The sealed AIO requires no coolant refills; clean the radiator fins and 140mm fan annually, and the PSU only needs occasional dust removal from its intake.

Which limit appears first during a sustained all-core workload on the i9-14900K with this cooling?

The CPU will reach its 6.00 GHz turbo ceiling and 36 MB L3 cache bandwidth before the 360mm AIO saturates, so frequency throttling occurs at the silicon limit.
