What should a Sydney data centre plan for with liquid cooling?
A Sydney AI data centre should plan direct-to-chip cold plates on GPUs and CPUs, a closed warm-water loop, and heat rejection sized for Western Sydney summer peaks. ToneCooling Australia supplies standard GB300 4G+2C and GB200 cold plate kits with downloadable datasheets, and custom cold plates for other platforms.
Sydney is Australia’s largest data-centre market, with major AI and hyperscale capacity expansion underway. Direct-to-chip liquid cooling lets operators raise rack density without expanding facility footprint or power headroom. See also national data centre cooling and liquid vs air cooling.
- Summer peaks
- Penrith Lakes recorded 48.9 °C on 4 January 2020, the highest temperature on record in the Sydney basin (Bureau of Meteorology). Size dry coolers and CDUs for the peak ambient, not the average.
- Loop temperature
- Warm-water supply (ASHRAE W32–W40 classes) keeps heat rejection possible on hot days and cuts chiller hours.
- Water
- Closed-loop cold plates recirculate coolant; see data centre water use and liquid cooling.
- Pressure budget
- Match cold plate pressure drop to the CDU: GB200 kit 35 ± 5 kPa at 2.5 L/min; GB300 GPU plate 12.06 kPa at 1.7 L/min (datasheets).

Frequently asked questions
Do you supply liquid cooling cold plates for Sydney data centres?
Yes. ToneCooling Australia supplies direct-to-chip cold plates and rack-level cooling hardware for Sydney AI and hyperscale data centres, supporting NVIDIA GB200/GB300/H200 and AMD EPYC SP5 platforms. Manufacturing is in Huizhou, China; AS/NZS documentation, customs and engineering support from Carlton, Victoria.
How much rack density can liquid cooling support in a Sydney DC?
Direct-to-chip liquid cooling supports approximately 80–120 kW per rack, versus roughly 8–25 kW for air cooling — enabling high-density AI clusters within existing Sydney facility footprints and power envelopes.
Which platforms do you cool for Sydney AI deployments?
NVIDIA GB200 (2,700 W/module), GB300 (4 GPU + 2 CPU kit, tested datasheet), H200 (8 × 700 W), and AMD EPYC SP5, with copper micro-channel cold plates and 100 % helium-leak and C-scan testing.
What is liquid cooling in data centres?
Liquid cooling in data centres moves heat from processors into a coolant instead of air. In direct-to-chip cooling, a cold plate sits on each GPU or CPU and a closed loop carries the heat to a coolant distribution unit (CDU) and then to dry coolers or a facility water loop.
How do Western Sydney summer temperatures affect liquid cooling design?
Heat rejection must work on the hottest days. Penrith Lakes recorded 48.9 °C in January 2020 (Bureau of Meteorology), so dry coolers and CDUs should be sized for peak ambient, and a warm-water supply temperature keeps the loop within its design envelope.
What compliance applies to data centre cooling hardware in NSW?
Cooling hardware is supplied with AS/NZS-aligned documentation; coolant loops follow ASHRAE W40 design. ToneCooling Australia Pty Ltd is an Australian entity (ABN 96 653 174 040) coordinating compliance from Carlton, Victoria.
