Common Applications
The N-ICH4090-X-V3 is a continuous-use, full-cover custom-loop block engineered around the INNO3D RTX 4090 X3 PCB family (AD102-300, 24GB GDDR6X, 16-pin power, 450W stock TDP). A nickel-electroplated high-purity copper cold plate contacts the GPU die through Bykski thermal paste while pre-cut thermal pads bridge the GDDR6X modules and VRM stage to the same cold plate. A stainless steel mid-panel keeps the block slim, the POM top contains the flow channels, and a black anodized aluminum backplate ships with the block but sits outside the coolant path. G1/4 threaded ports support series or parallel loops.
Frequently Asked Questions
Q: Which RTX 4090 cards is the N-ICH4090-X-V3 compatible with?
A: INNO3D RTX 4090 Ice Dragon Super Edition, RTX 4090 X3 OC 24GB, RTX 4090 D X3, RTX 4090 D SUPER, AX Gaming RTX 4090 X3W 24G and RTX 4090 D X3W 24G. Verify your PCB photo before buying because INNO3D iCHILL X3 uses a different block.
Q: What materials are used in the block?
A: Nickel-electroplated high-purity copper cold plate, stainless steel mid-panel, POM top, and black anodized aluminum backplate that does not contact coolant.
Q: Are thermal pads and screws included?
A: Yes. The package ships with the block, backplate, mounting hardware and Bykski thermal paste. Pre-cut thermal pads are included for memory and VRM contact points.
Q: Does it have RGB and which voltage?
A: The V3 revision is a non-illuminated block. Earlier non-V3 variants used 5V addressable RGB which is not interchangeable with 12V RGB headers.
Q: What thread size and flow path does the block use?
A: G1/4 inch threaded ports with top and bottom inlet/outlet locations, so the block can be daisy-chained in series or run in parallel with other cards.
