System Overview

The Adamant Custom desktop is a 20-core liquid-cooled workstation built around an Intel Core Ultra 7 265K processor and an Nvidia GeForce RTX 5090 graphics card with 32 GB of video memory. It ships with 32 GB of DDR5 RAM, a 4 TB NVMe SSD and a 10 TB hard drive, targeting creators and gamers who need high multi-threaded throughput and large local storage in a single Windows 11 Pro machine.

Thermals & Power

A 240 mm quiet-edition AIO cooler handles the CPU while three 120 mm front fans and a 140 mm PSU fan move air through the Antec P20 mid-tower case. The Thermaltake Toughpower 1000 W 80 PLUS Gold supply uses Japanese main capacitors and includes over-voltage, under-voltage, over-power and short-circuit protection. Dust filters on the bottom, front and top panels help maintain airflow over time.

Sustained Load Behaviour

Under prolonged workloads the liquid loop keeps the 20-core processor near its 5.50 GHz boost ceiling while the 30 MB L3 cache feeds the RTX 5090 without throttling. The Samsung 990 PRO SSD delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s across the PCIe 4.0 x4 interface. Wi-Fi 7 and Bluetooth 5.4 remain stable alongside the 2.5 Gb Ethernet link during extended transfers.

Questions about this item

How is the 240 mm liquid cooler installed, and which step is often missed?

The cooler arrives pre-fitted to the CPU on the LGA 1851 socket; the step builders sometimes skip is connecting the pump header and the two 120 mm radiator fans to the motherboard so the curve controls coolant temperature.

What maintenance or replacement will the 240 mm AIO and the 10 TB HDD need later?

The sealed AIO requires no refill, but dust should be cleared from the radiator fins every 6–12 months; the mechanical HDD will eventually wear out and should be backed up and replaced after several years of heavy use.

Which limit appears first during sustained loads: the CPU turbo ceiling, the 240 mm radiator capacity, or the 1000 W PSU headroom?

The 240 mm radiator typically saturates before the 1000 W PSU or the CPU turbo ceiling, so coolant temperature becomes the limiting factor during prolonged heavy workloads.
