Asetek invented its closed water cooling circuits in 2003, and received its first OEM order from HP back in 2007. At that time, it was COMPLETELY new, but HP nevertheless took the lead and implemented it in its gaming PCs and commercial workstations.
Since that modest beginning, Asetek has sold more than six million(!) of these closed circuits for PCs, servers and data centers; it currently produces around 100,000 systems per month. Customers range from leading consumer brands to the big OEMs we all know, such as Acer, Asus, Dell, HP, Fujitsu, Intel etc.
We in Denmark and the EU are five to ten years behind in the use of water cooling for data centers. Asetek has several big data cente installations in the USA, Singapore, Japan, Taiwan and elsewhere, and the customers range from US government customers such as the Department of Defense and Department of Energy to a number of universities, while Asetek also has several government and commercial customers in Asia. So yes – you could say the technology is mature!
Most of Asetek’s current end-customers use water cooling to save energy on cooling. District heating is not used in many places outside Denmark and the EU, so this implementation is not yet all that widespread, but, precisely because of our high consumption of district heating, we in Denmark have a unique opportunity to take the lead.
