Liquid Cooling Solution
Unparalleled cooling performance for the modern data center
Challenges
As new generations of servers come online to deliver massive amounts of processing for modern data centers, the heat generated by increasingly dense clusters of CPUs and GPUs inevitably leads to challenging thermal dissipation scenarios. Prevailing computer room air conditioning (CRAC) systems require high energy usage and complex cooling fan setups operating around the clock, which generates a significant percentage of data center operational expenditures (OpEx). Liquid cooling becomes the energy-efficient solution that can scale as cluster density and processing loads continue to increase.
The top four reasons to choose liquid cooling
-
Denser Computational power
While a server rack with conventional air cooling can manage up to 30 kW of heat dissipation, direct liquid cooling can scale much more. This increase in thermal capacity allows more computational density for servers, upgrading the scale of a data center to accelerate and optimize complex workloads. -
Much improved PUE
The thermal efficiency of liquid cooling dramatically improves the PUE of a data center by reducing the demand for CRAC and cooling fans, and liquid coolant is a more efficient medium of heat exchange than air. -
Save on OpEX in long term
A data center with liquid cooling is customarily designed for heat recirculation. The hot coolant exiting a server is directed though a heat exchanger system that recycles heat into more energy, further reducing OpEx for utilities. Thanks to this system, the initial cost of most direct liquid cooling servers can be recovered within the first 12 months of operation, providing potentially significant savings over time. -
A much quieter environment
In addition to saving energy through the reduction of CRAC systems and fans, liquid cooling can also reduce fan noise, leading to a healthier work environment for data center personnel. The average acoustic impact of air-cooling is between 75 dBA and 95 dBA, whereas liquid cooling averages below 75 dBA. Enterprise, office and military data centers can particularly benefit.
The considerations on building liquid cooling
Before choosing the cooling solution for your data center, consider these specific metrics.
Energy consumption
- The amount of heat in kW that you expect to be removed from a rack and an individual server
- The different categories of expected workloads that will require a CPU to operate at full capacity
Operational and capital expense
- The estimated energy bill costs in 1 year to 3 years
- Infrastructure, deployment and maintenance expenses
- The cost to migrate from air cooling to liquid cooling
Performance density
- The amount of increasing computing performance per square foot
ASUS liquid cooling solutions
Direct Liquid Cooling (DLC)
Direct to Chip (D2C)
This design places a cold plate directly on top of components such as CPUs and GPUs and continually funnels the heat they generate through a liquid coolant network to a cooling distribution unit (CDU) located in the rack. The CDU takes the incoming heat, dissipates it, and uses a pump to circulate the chilled coolant back into this closed-loop system.
Immersion Cooling
This method of cooling submerges an entire server into a thermally conductive dielectric fluid for maximum heat dissipation. It is generally regarded as the most energy-efficient form of liquid cooling on the market, and it can significantly improve compute footprints and infrastructure.
