1U Liquid Cooling Module
1. General Information
The 1U Liquid Cooling Module (Server Level Sealed Loop) cooler replaces the less efficient air coolers and enables air-cooled data centers to utilize the highest performing CPUs and GPUs. The superior cooling characteristics of the liquid cooler enables server LSL to capture more heat and transfer it into the air
This product specification covers all components in the cooler
