Frequently asked questions
Do you supply liquid cold plates for RTX 3090 workstations?
Yes. ToneCooling Australia supplies a copper liquid cold plate (model T-HS202311) rated to 350W for NVIDIA RTX 3090 dual-slot workstation GPU deployments.
Is this suitable for multi-GPU rendering/AI workstations?
Yes. The dual-slot design supports dense multi-GPU workstation builds; port location and manifold routing are engineered from your chassis drawing.
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 MOQ and lead time?
Prototype MOQ is 5 pieces with a typical 7-15 business day 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.
How is this different from a retail RTX 3090 water block?
This is an engineered industrial cold plate validated to IATF 16949-aligned processes with per-unit leak testing and DFM engineering review — not a fixed-fit retail water-cooling product.
