The Granzon GBN-AS4080STRIX Full Armor GPU Block fits ASUS ROG Strix and TUF RTX 4080 cards, engineered specifically for sustained AI inference workloads that push 320W continuously—not bursty gaming sessions.
Stock coolers hit 45-65 dBA under LLM load; this full-coverage block drops noise below 30 dBA, critical for home offices and bedroom AI rigs. Full-wrap copper cold plates press directly on all 16GB of GDDR6X VRAM, eliminating the 92°C throttling point that cripples sustained Stable Diffusion and Ollama inference.
Dual RTX 4080 configurations (640W combined) are physically impossible with air cooling—this block enables multi-GPU local LLM setups in standard ATX cases. For 24/7 reliability, the nickel-plated copper construction maintains thermal headroom through multi-day training runs without thermal degradation.
Nickel-plated copper base, G1/4 standard threads, integrated aluminum backplate. Ships worldwide.
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.
