Asetek was one of the pioneers of closed-loop liquid cooling systems in the early 2000s and patented many technologies covering all-in-one liquid coolers. This put Asetek in a unique position to sue competitors for patent infringements or make them its customers and produce LCSs for them. However, as suppliers of closed-loop liquid coolers find ways to overcome Asetek’s patents to circumvent some of the company’s patents while the other expires, they lower their orders to the Danish liquid cooling giant.
“Asetek A/S has received updated purchase forecasts from a number of the company’s largest OEM customers,” a statement issued this week reads. “Based on these new forecasts, the expected increase in demand in the second half of 2024 of the company’s liquid cooling products may not materialize. This will result in a significant decline in Group revenue and profitability for 2024 compared to the revenue and profitability guidance issued on June 08, 2025.”
Indeed, some of the popular LCS makers we spoke to atComputexearlier this month emphasized that Asetek does not make some of their latest products or use any of Asetek’s patents. As a result, the Danish company will not get any licensing fees or manufacturing orders in the coming months.
As one of the world’s largest makers of liquid cooling systems, Asetek has dozens of clients, including PC OEMs, cooling system suppliers, and even data center developers. For obvious reasons, Asetek does not disclose the names of its customers who have cancelled their orders or what kind of products it ships to them.
While Asetek’s traditional PC customers can indeed produce their liquid coolers themselves, they are hardly driving revenue growth for the company, unlike data center clients, who are increasingly buying liquid coolers. Unfortunately, we have no idea which of Asetek’s clients abruptly cut their orders to the liquid cooling giant.
“The management team and board of directors of Asetek will consider the long- and short-term consequences of the weakened and uncertain market situation,” a statement by the company reads. “The assessment today is that the negative trend in revenue may continue into 2025. Based on this, a plan containing initiatives to navigate the short and long-term challenges will be developed and then communicated as soon as possible.”
