COPENHAGEN – A key patent held by Danish company Asetek, covering integrated pump CPU coolers for all-in-one (AIO) liquid cooling systems, expired May 6, 2025. The patent, PCT/DK2005/000310 (US8240362), has significantly influenced AIO cooler designs for nearly two decades.
While numerous manufacturers offer AIO coolers, many designs are based on Asetek’s technology. Coolit, a Canadian company, is a notable option, having previously resolved patent disputes with Asetek out of court. Other manufacturers have faced legal challenges from Asetek regarding patent infringement.
Some manufacturers have circumvented Asetek’s patent by separating the water pump and cooling plate into distinct chambers within the radiator housing. Examples include EK Water Blocks’ EK-Nucleus AIO series and Alphacool’s Eisbaer models, which utilize a DDC pump on the CPU cooler. Aqua Computer and Alphacool also offer radiators with integrated pumps.
End of a 20-year Run
Asetek founder André Sloth Eriksen secured patent PCT/DK2005/000310 on May 6, 2005. Patents typically expire after 20 years, a date noted by Google Patents.
The expiration of this patent may spur innovation in the AIO liquid cooling sector. Manufacturers can now explore new designs without fear of legal repercussions,perhaps leading to a wider variety of cooling solutions.
Asetek, in its recent quarterly report released in late April, indicated an openness to selling its radiator business. The company also reported interest from data centers regarding potential cooling system partnerships. Along with liquid cooling, Asetek manufactures peripherals for racing simulators.

Asetek Patent Expiration: What Does It Mean for CPU Coolers?
Here’s a breakdown of what you need to know about the recent Asetek patent expiration and its impact on the CPU cooler market,presented in a Q&A format:
What Asetek Patent Expired,and What Did It Cover?
Q: What patent did Asetek hold that recently expired?
A: Asetek’s key patent,PCT/DK2005/000310 (US8240362),covering integrated pump CPU coolers used in all-in-one (AIO) liquid cooling systems,expired on May 6,2025.This patent considerably influenced the design of AIO coolers for nearly two decades.
Q: What does “integrated pump” mean in the context of CPU coolers?
A: In AIO liquid coolers, an integrated pump refers to the water pump being built directly into the CPU block (the part that sits on top of the CPU). This is different from designs wich have the pump integrated into the radiator.
The Impact of the Patent Expiration
Q: What’s the importance of this patent expiration?
A: The expiration of this patent opens the door for potentially notable innovation in the AIO liquid cooling sector. Manufacturers can now explore new designs and technologies without fear of legal challenges from Asetek related to this specific integrated pump technology. this could lead to a wider variety of AIO cooling solutions.
Q: How has Asetek’s patent influenced the CPU cooler market previously?
A: Many AIO cooler designs on the market relied on Asetek’s technology due to this patent.Numerous manufacturers have offered AIO coolers based on Asetek’s designs. Some manufacturers even faced legal challenges from Asetek regarding patent infringement, highlighting the patent’s dominance.
Q: Can you give some examples of manufacturers that have used choice approaches to circumvent Asetek’s patent?
A: Yes. Some manufacturers have designed around Asetek’s patent by separating the water pump and cooling plate into distinct chambers, frequently enough integrating the pump into the radiator. Examples include:
EK Water Blocks’ EK-Nucleus AIO series.
Alphacool’s Eisbaer models (which use a DDC pump on the CPU cooler).
Aqua Computer also offers radiators with integrated pumps.
Alphacool also offers radiators with integrated pumps.
A Closer Look at Asetek
Q: who is Asetek, and what does the company do?
A: Asetek is a Danish company primarily known for its liquid cooling solutions. Their product range includes all-in-one (AIO) liquid coolers and components for custom cooling loops. Beyond liquid cooling, Asetek also manufactures peripherals for racing simulators.
Q: What is Asetek’s current situation?
A: Asetek, in its late April quarterly report, indicated an openness to selling its radiator business. They also reported interest from data centers regarding potential cooling system partnerships.
Q: How long was Asetek’s patent in effect?
A: Asetek founder André Sloth Eriksen secured patent PCT/DK2005/000310 on May 6, 2005. Patents generally last for 20 years, confirmed by information noted by Google Patents.
Potential Future developments
Q: What changes might we see in the CPU cooler market due to this patent expiration?
A: The expiration may stimulate innovation. Manufacturers could explore new designs, potentially improving cooling performance, lowering costs, or introducing novel features.
Q: Will we see a sudden flood of new cooler designs?
A: While the patent expiration removes a legal hurdle, new product advancement takes time. We’ll likely see a gradual introduction of new coolers incorporating previously restricted technologies or design approaches.
Q: Can you summarize the key takeaways in a table for easy reference?
A: absolutely. Here’s a summary:
