What Alphacool does

Alphacool International GmbH is a German privately held water cooling specialist headquartered in Braunschweig, founded in 2003 by a group of PC cooling enthusiasts. The company designs, manufactures and distributes liquid cooling components and integrated solutions for desktop PCs, workstations, servers and industrial electronics, operating across three locations in Germany (R&D, design and customer support), China (manufacturing) and France (sales and marketing) with a global headcount of almost 400 employees. Its product portfolio spans CPU coolers, full-coverage GPU coolers, copper and aluminium radiators, pumps, reservoirs, distribution plates and fans, organised under the consumer-facing CORE and APEX sub-brands and the B2B Enterprise Solutions (ES) division. Core proprietary technology includes the patented reverse flow microstructure water cooling unit, the compact FKT liquid cooling unit, quick release coupling systems, the COPPERcore™ all-copper radiator platform and a 3D jetplate with cross-slot base.

Alphacool earns revenue through four streams: direct B2C e-commerce sales of components and custom cooling systems through its own online shop; B2B enterprise sales of custom server and industrial cooling solutions priced per quote; OEM manufacturing of white-label cooling products for global brands including AMD, MSI, Sapphire, ASUS, Colorful, Medion, Erazer and iChill; and professional services covering consultation, 3D visualisation, custom design and optimisation. Distribution combines direct e-commerce, an enterprise configurator tool, a global reseller and dropshipper network, and direct enterprise field sales. Reference customers span datacenters (Supermicro, InoNet, Thomas-Krenn, Cloud&Heat), semiconductors (Qualcomm), aerospace and drones (ZARM, DLR, Wingtra), automotive and industrial (Vaillant, Deutsche Bahn, Alva Motor), medical (University Hospital Heidelberg, Wavemed, DEYMED) and optics (ams-OSRAM, Jenoptik). The company holds ISO 9001:2015 certification, GDPR compliance and consecutive PCGH Manufacturer of the Year awards in 2023 and 2024, and continues to operate without external private equity or venture capital backing under founder-led management.
