Frequently asked questions
Do you supply liquid cold plates for AMD EPYC SP3 servers?
Yes. ToneCooling Australia supplies a copper liquid cold plate (model T-HS202318) rated to 260W for AMD EPYC SP3 (LGA 4094) server deployments, TLP diffusion bonded.
What coolant and flow rate does it use?
Rated performance is tested with 25% EGW coolant at 40°C inlet, 1 LPM flow rate at approximately 3 kPa pressure drop, holding surface temperature at or below 55°C.
Can the design be customised?
Yes. Port locations, mounting pattern, dimensions and surface finish are customised from your drawings, with CFD validating the change before tooling.
What is the Quantity and lead time?
Prototype orders start from 1 piece with a 4–6 week prototype lead time from approved drawing and purchase order; production lead time is confirmed per volume.
Where is this cold plate manufactured?
Manufacturing is performed at the ToneCooling facility in Huizhou, Guangdong, China. ToneCooling Australia Pty Ltd (Carlton, VIC) is the AU RFQ and engineering-coordination entity and does not manufacture.
Do you publish Quantity and lead time like other SP3 cold plate suppliers?
Yes — prototypes from 1 piece and a 4–6 week prototype lead time are published up front, alongside a full spec table and FAQ, rather than a quote-only marketing page.
