COOLING SOLUTIONS FOR THE HIGHEST DEMANDS
The IT world would be unthinkable without powerful cooling. However, the required cooling performance is often bought dearly with loud fans or inferior components lacking the reliability that is so crucial in this domain.
We develop and market cooling solutions for the highest demands in performance, quietness and quality. Whether it’s about your home PC, professional workstations and servers or tailored industrial applications: With our products, you’ll experience acoustically optimised premium cooling at the highest level!

ABOUT US
Founded in Vienna, Austria in the year 2000 by Alexandra and Roland Mossig, Rascom Computerdistribution quickly developed into a specialist for high grade cooling components. In addition to the growing overclocking trend and tailor-made, more powerful heatsinks, acoustically optimised components soon became a key focus.
As of 2002, Rascom acted as an OEM supplier for one of the then-leading European quiet cooling brands and in 2005, the company took the next step: In cooperation with its development and manufacturing partner Kolink International, Rascom launched Noctua.
While Rascom originally continued to pursue its regular distribution business, Noctua soon became
the exclusive focus, growing from a newcomer in the field to a renowned leader in its market segment. Between the founding of Noctua in 2005 and 2025, Rascom grew from 10 to over 80 employees. Since 2012, Rascom has also been operating a dedicated R&D department in Linköping, Sweden, and in 2026, Rascom opened another R&D site in Hong Kong.
Until today, Rascom remains a founder-owned, founder-run business. Regardless of its considerable growth and structural evolution over the years, the Viennese company is still a family business in the best sense of the word: Its long-term continuity in management, vison and key responsibilities as well as its positive, enabling and inclusive work culture are a key backdrop of Noctua’s success.

In the end, it’s the details and the time you take to get them right that make the difference. We develop products with the goal of ensuring they continue to function reliably years later and prove their worth in everyday use.
This requires attention to detail, a precise understanding of how the product will be used, and a willingness to think things through to the very end.

NOCTUA
Noctua’s award-winning, premium quality quiet cooling components are internationally renowned for their superb acoustics, industry-leading performance-to-noise efficiency and remarkable longevity. Since its foundation in 2005, the Austrian manufacturer’s engineering-first mindset, history of innovations and relentless pursuit of continuous optimisation have become just as iconic as its long-term product support and excellence in customer service. Today, PC enthusiasts and industry clients alike swear by the signature blend of cutting-edge performance, outstanding quietness and ultimate reliability that makes Noctua’s products unique.

CPU Cooling
Best-in-class quiet cooling performance, uncompromising reliability and legendary longevity thanks to the availability of free-of-charge mounting upgrade kits: This is what has made our CPU coolers the go-to-choice for customers who are looking for futureproof premium solutions.

Fans
Our award-winning axial fans are renowned for their state-of-the-art performance-to-noise efficiency and outstanding longevity. Spanning from 40 to 200mm size and comprising 5, 12 and 24V options, our portfolio not only caters to quiet PC cooling enthusiasts but also covers various other use-cases including industrial heavy-duty applications that require high-speed fans with IP67 ingress protection.

Industrial Applications
While Noctua originates from PC cooling, the outstanding quiet cooling efficiency and superior reliability of our fans and heatsinks are equally beneficial for a wide range of industrial applications. We also support our B2B clients through thermal engineering consultancy and can offer product customisations such as different fan cables and connectors.
LOCATIONS AND PARTNERS
Austria, Taiwan, Sweden and Hong Kong: behind Noctua stands a closely connected network of international teams and partners. From Rascom’s Vienna headquarters and founding partner Kolink in Taipei to R&D departments in Linköping and Hong Kong’s Tsuen Wan district, each location contributes its own strengths, but all share the same commitment to perfectionism, long-term thinking and products that are built to last.

RASCOM HEADQUARTERS
Vienna, Austria
Our Vienna headquarters are at the very heart of Noctua’s operations. From strategic vision, product management, business analytics, international sales, industrial client relations to engineering, technical validation, visual design, marketing, customer support, logistics and warehousing – this is where the threads come together.
Interfacing closely with the other locations, our R&D team in Vienna is focused on in-depth acoustic, performance and mechanical analysis as well as on developing, refining and automating advanced measurement and validation systems. The headquarters also host our sales and engineering support for industrial clients, our customer service department that assists end users around the globe as well as all marketing and PR activities from sponsoring and press work to social media.
Our Vienna warehouse remains our central logistics hub from where we coordinate international stock flows and distribute goods all over the world. We also collect, inspect and refurbish returned items with the goal of reducing unnecessary waste to an absolute minimum.
KOLINK INTERNATIONAL CORP.
Taipei, Taiwan
Established in 1995, Kolink is a Taiwanese cooling specialist that designed and manufactured high-performance heatsinks for various brands before co-founding Noctua with Rascom in 2005. Since then, Kolink has dedicated itself exclusively to Noctua products and has grown from 20 to more than 200 employees, continually expanding both its R&D and manufacturing capabilities. Today, all key steps of heatsink manufacturing such as heatpipe production, heatsink assembly, soldering and base convexity control are done in-house at Kolink’s factory.
Just like Rascom, Kolink is still a founder-owned, founder-run family business with long-term continuity in leadership positions: Co-founder Kuo-Jen (Tim) Chu has led Kolink as CEO since the very beginning, his son Shih-Hsiang (Alex) Chu advanced to the CTO position in 2021 and other key employees have been on board for more than 20 years.
At Noctua, Kolink is not only responsible for supply chain management, manufacturing, packaging and on-site quality control, but also contributes to R&D and handles international export logistics.


Our guiding vision is that customers should not only be satisfied with their Noctua products, they should be proud of them.

RESEARCH AND DEVELOPMENT
Linköping, Schweden
Since 2012, Rascom has operated a dedicated R&D department in Linköping, Sweden, which continues to work under its own company name, RotoSub AB. Founded in 2004 by Lars Strömbäck, who took on the role of Noctua’s CTO shortly after joining Rascom, RotoSub developed extensive expertise in fan aerodynamics, noise propagation and acoustic optimisation, which has helped to push Noctua’s fan engineering to a new level.
Today, our Linköping team not only directs Noctua’s fan development from aerodynamic design and DFM to motor engineering but also leads other key R&D endeavours such as the two-phase thermosiphon cooling project. Additionally, the Linköping team is responsible for electronics products, handles certifications as well as compliance and closely collaborates with Vienna’s creative team on industrial design.
