Liquid-cooled 24-core workstation

The Adamant Custom desktop pairs a 24-core Intel Core i9-14900K with a 360mm AIO liquid cooler, 32GB DDR5 and a GeForce RTX 5090 32GB GPU. A 4TB Samsung 990 PRO NVMe drive and Gigabyte Z790 AORUS motherboard complete a system built for heavy rendering, simulation and 4K gaming workloads.

Thermals noise and 1200W Gold power

The 360mm Quiet Edition AIO handles the 24-core CPU while the Cooler Master HAF 500 case moves air through two 200mm front ARGB fans, a rear 120mm ARGB fan and a dedicated 120mm GPU fan. The Thermaltake Toughpower 1200W 80 PLUS Gold unit uses Japanese main capacitors and a 140mm fan, delivering over-voltage, under-voltage, over-power and short-circuit protection.

Accessories that change daily use

Windows 11 Pro is pre-installed on the 4TB NVMe SSD, which reads up to 7450 MB/s and writes up to 6900 MB/s. The Z790 AORUS board adds Intel 2.5Gb Ethernet, Wi-Fi 6 and Bluetooth 5.2, plus six SATA 6Gb/s ports with RAID 0, 1, 5, 10 support and four M.2 slots for future storage expansion. Realtek 7.1 surround audio and a front-panel USB 3.2 Gen 2 Type-C port round out the connectivity.

Questions about this item

How do I install the 360 mm AIO liquid cooler on the Intel Core i9-14900K and what step is often missed?

Mount the 360 mm radiator using the case fan positions, attach the pump block to the LGA 1700 socket with the supplied bracket, and connect the pump header to the CPU_FAN connector on the GIGABYTE Z790 AORUS motherboard so the BIOS can monitor pump speed.

What maintenance or replacement will the liquid cooling and PSU need later?

The 360 mm AIO is a sealed unit requiring no refill; plan to replace the thermal paste on the i9-14900K every few years. The Thermaltake Toughpower 1200W 80 PLUS Gold PSU uses a 140 mm fan and Japanese capacitors — clean dust from its intake periodically.

What limit appears first during sustained loads on this system?

The Intel Core i9-14900K 24-core CPU can draw high power at up to 6.00 GHz boost clocks; the 360 mm Quiet Edition AIO and 1200 W Gold PSU are sized for this load, so the CPU thermal junction limit is the first boundary reached under prolonged heavy work.
