Coolermaster is characterised since the establishment 1992 as a manufacturer of high-quality cooling solutions. It cooperates among other things with AMD and Intel with the production of CPU radiators and produces for PC assembler such as IBM, HP, Fujitsu Siemens or Medion. Like many radiator manufacturers they lead also housings and power packs in the program. To the test we received the 600W model with passively PFC, which high achievement promises with deep purchase price from the extreme power duo.
