Frequently asked questions
Do you supply liquid cold plates for RTX 4090 dual-slot builds?
Yes. ToneCooling Australia supplies a copper liquid cold plate (model T-HS202305) rated to 450W for NVIDIA RTX 4090 dual-slot workstation GPU deployments.
What's the difference between the single-slot and dual-slot RTX 4090 cold plates?
Both cool the same RTX 4090 GPU at 450W but differ in envelope and slot-width to fit different chassis designs — dual-slot is 270x97x29.7mm; the single-slot sibling has a slimmer footprint. Tell us your chassis constraint and we'll confirm the right fit.
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 4090 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.
