The Bykski N-GV4080EOC-X-V2 is a full-coverage water block engineered for Gigabyte RTX 4080 16GB Eagle, AERO, Master, and Gaming variants—cards increasingly deployed in home AI workstations for local LLMs and Stable Diffusion. At 320W TDP, stock cooling pushes 45–55 dBA during sustained inference; this block drops operational noise below 30 dBA, transforming bedroom or home-office rigs into silent 24/7 compute nodes.
VRAM thermal protection is critical: the RTX 4080's 16GB GDDR6X modules throttle at 92°C under continuous token generation. Bykski's precision-milled cold plate presses nickel-plated copper directly against GPU, VRAM, and VRM—eliminating the thermal lag that degrades inference consistency. For builders running dual RTX 4080s in a single chassis, no air solution exists; this block's slim profile and G1/4 threading enable parallel loop configurations that 700W+ multi-GPU setups demand.
Many 4080s entering the second-hand market carry degraded factory thermal pads. Installing this block performs a full thermal reset, restoring base clocks and eliminating the hidden throttling that silently slows model loading. The POM + full metal construction withstands continuous duty cycles that gaming workloads never replicate—24/7 reliability for diffusion training, batch inference, or Ollama serving.
Specs: Nickel-plated copper cold plate, G1/4 BSPP threading, integrated aluminum backplate for PCB rigidity. 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.
