Asetek liquid cooling technology has been thoroughly tested and certified by an independent outside lab to operate without maintenance for over 50,000 hours – that is over 5 years of continuous, 24/7, operation. In addition, Asetek tests 100% of all liquid cooling systems by filling them first with helium and then inspecting for integrity failures using helium detection equipment. This ensures each liquid cooler will operate properly from the day it is put in service.
