The Bykski N-YT4080-X is a full-cover water block engineered for the Yeston RTX 4080 16G D6X Sugar, purpose-built for local AI workloads running Stable Diffusion, Ollama, and LLM inference at home. With a 320W TDP under sustained load, stock air cooling pushes 50-60 dBA—unacceptable for bedroom or home office rigs. This block drops noise below 30 dBA while maintaining thermal headroom for continuous operation.
VRAM protection is critical: The RTX 4080's 16GB GDDR6X modules throttle at 92°C during prolonged inference sessions. Bykski's precision-milled cold plate presses directly onto every memory chip and VRM phase, eliminating the thermal lag that causes clock instability in air-cooled setups running 24/7. For dual-GPU AI builds—two 4080s pulling 640W combined—water cooling is the only viable thermal solution that fits standard ATX cases.
Silence, reliability, and multi-GPU viability define this upgrade. Whether you're reviving a thermally degraded card or building a new local LLM workstation, the full-coverage design resets thermal performance for years of uninterrupted inference. Nickel-plated copper construction, G1/4 standard threading, integrated aluminum 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.
