The Bykski N-MX4090TB-X is a full-cover GPU water block engineered specifically for the Maxsun RTX 4090 Turbo 24G, targeting the 450W sustained loads of local LLM inference and Stable Diffusion generation. Unlike gaming workloads that spike and recover, AI inference demands hours or days of continuous operation—exactly where stock triple-fan coolers fail, screaming at 50-60 dBA and pushing GDDR6X junction temperatures past 90°C.
Silence is non-negotiable for bedroom and home office AI rigs. This water block transforms acoustic output to under 30 dBA, replacing unbearable fan roar with near-inaudible pump flow. VRAM protection comes from precision-machined nickel-plated copper pressing directly onto all 24GB of GDDR6X modules, eliminating the thermal throttling that cripples inference speed when junction temps hit 92°C.
For multi-GPU setups—dual RTX 4090s pulling 900W in a single case—air cooling is physically impossible. This block enables 24/7 reliability through sustained thermal headroom that blower-style coolers cannot provide, while also serving as a used GPU revival solution for thermally degraded cards whose original pads have hardened after years of heavy AI workloads.
Nickel-plated copper construction, G1/4 threading, integrated aluminum backplate for VRM cooling. Ships worldwide.
Frequently Asked Questions
Is this waterblock compatible with my RTX 4090?
This Bykski waterblock is designed for the RTX 4090. 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 4090 be with water cooling?
Stock RTX 4090 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 450W 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 4090?
- 24/7 Stable Diffusion inference pushes VRAM to 90°C+ junction; full-cover waterblocks eliminate throttling
- Dual-4090 builds (900W total GPU) are physically impossible in normal cases without water cooling — 3-slot air coolers block each other
- The #1 used-GPU-to-waterblock conversion target — buyers snagging secondhand 4090s want silent 24/7 AI rigs
Full-cover water blocks cool GPU die + VRAM + VRM simultaneously — unlike air coolers that only target the GPU die.
