The Bykski N-IG4080ULOC-X is a full-coverage water block engineered for the Colorful iGame RTX 4080 Ultra, Battle-ax, and Onda RTX 4080 variants—designed specifically for home AI inference workloads where 320W sustained loads push stock fans past 60 dBA. Unlike gaming bursts, local LLM and Stable Diffusion sessions run for hours or days, making silence and thermal stability non-negotiable in bedroom or home office environments.
Silence & VRAM Protection: Stock cooling leaves GDDR6X memory modules hovering near 92°C throttling thresholds during prolonged inference. This block presses nickel-plated copper directly against every VRAM chip and VRM phase, dropping noise below 30 dBA while eliminating thermal-induced slowdowns that corrupt token generation speed.
Dual-GPU Necessity & 24/7 Reliability: Two RTX 4080s in a single case exceed 600W—no air solution exists. Water cooling becomes mandatory for multi-GPU Ollama or Stable Diffusion farms. The included aluminum backplate prevents PCB flex and secondary heat soak during continuous operation, ensuring consistent performance across multi-day training runs.
Used GPU Revival: Even newer 4080 cards suffer thermal pad degradation from factory assembly; installing this block performs a complete thermal reset, restoring original boost behavior. Nickel-plated copper construction, G1/4 threading, full backplate included. Ships worldwide.
Frequently Asked Questions
Is this waterblock compatible with my RTX 4080?
This Bykski waterblock is designed for the RTX 4080. Check the product title for specific card brand compatibility — non-reference PCB designs (ASUS Strix, MSI Suprim, etc.) require model-specific blocks. Reference/Founders Edition cards use a different block.
How much quieter will my RTX 4080 be with water cooling?
Stock RTX 4080 coolers run at 45-65 dBA under sustained AI workloads like Ollama or Stable Diffusion. A full-cover waterblock reduces noise to under 30 dBA — quieter than a refrigerator. VRAM temperatures also drop from 90°C+ to 60-70°C, preventing thermal throttling during long inference sessions.
What else do I need for a complete loop?
Besides this waterblock, a complete custom loop needs: a radiator (360mm minimum for 320W TDP), a D5 or DDC pump with reservoir, G1/4 fittings (8-12 pieces), tubing (soft or hard), and coolant. FormulaMod carries all components — browse our AI Workstation Cooling collection for complete setups.
Can I run this 24/7 for AI inference?
Yes. Water cooling is designed for sustained loads, unlike air coolers which rely on fan speeds that create noise. A properly maintained loop can run 24/7 indefinitely with coolant changes every 12-18 months.
Does FormulaMod ship to the USA and Europe?
Yes. We ship worldwide from our Shenzhen warehouse. USA and EU orders typically arrive within 7 days. All products are covered by our return policy.
Why Water Cool the RTX 4080?
- Waterblock unlocks dual-4080 configurations
Full-cover water blocks cool GPU die + VRAM + VRM simultaneously — unlike air coolers that only target the GPU die.
