Adamant Custom 20-Core Workstation

The Adamant Custom business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB DDR5 memory and an Nvidia RTX PRO 2000 Blackwell 16GB GPU. It targets engineers and designers who run SolidWorks modelling and AI workloads on a single Windows 11 Pro 64-bit tower.

240mm AIO Liquid Cooling Thermals

A 240mm Quiet Edition liquid cooler handles the CPU while the Antec P20 case supplies three 120mm front fans and dust filters on bottom, front and top. The Thermaltake Smart 850W 80 PLUS Bronze PSU uses a 140mm fan with Japanese main capacitors and over-voltage, under-voltage, over-power and short-circuit protection.

Upgrade From Older CAD Towers

This system replaces ageing workstations that cannot feed 192GB DDR5 or a PCIe 4.0x4 SSD reading at 7450 MB/s and writing at 6900 MB/s alongside 10TB HDD capacity. The jump is worth it when projects demand 20 threads at up to 5.50 GHz, Wi-Fi 7 connectivity and Thunderbolt 4 I/O in one chassis.

Questions about this item

How is the 240 mm liquid cooler mounted to the LGA 1851 socket?

The 240 mm AIO uses the standard LGA 1851 mounting bracket; the step most people miss is tightening the four thumbscrews in a diagonal sequence so the cold plate makes even contact with the Core Ultra 7 265K heat spreader.

Which component will need replacement first — the Samsung 990 PRO 2 TB NVMe or the 10 TB HDD?

The 10 TB hard drive has moving parts and a 256 MB cache, so it typically reaches its wear limit before the solid-state 990 PRO under heavy write workloads.

What thermal limit appears first when the 20-core CPU sustains 5.50 GHz across all cores?

The 240 mm liquid cooler’s radiator capacity becomes the bottleneck; coolant temperature rises until the CPU throttles to protect the 30 MB L3 cache and 20 threads.
