The Granzon GBN-GV4080EOC full-coverage water block is engineered for Gigabyte RTX 4080 Eagle, AERO, Master, and Gaming variants—specifically targeting the 320W sustained loads of local LLM inference and Stable Diffusion generation. Unlike stock coolers that scream at 45-65 dBA during hours-long model training, this block drops noise below 30 dBA, making bedroom and home office AI rigs actually livable.
VRAM protection is critical: the RTX 4080's 16GB GDDR6X memory modules throttle at 92°C during continuous token generation. Granzon's precision-milled copper cold plate presses directly onto every VRAM chip, eliminating the thermal lag that air coolers cannot address during 24/7 inference sessions. This sustained thermal headroom is non-negotiable when your model runs overnight—not the bursty spikes of gaming workloads.
Dual-GPU necessity: two RTX 4080s (640W combined) in a single case is physically impossible with air cooling. This block enables compact dual-4080 configurations for Ollama and local LLM parallelism, with full nickel-plated copper construction and G1/4 threading for reliable loop integration. Includes integrated backplate for PCB rigidity during continuous operation.

Frequently Asked Questions
Is this waterblock compatible with my RTX 4080?
This Granzon 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.
