The Bykski N-EV3090FTW3-X is a precision full-cover water block engineered specifically for the EVGA RTX 3090 / 3080 Ti / 3080 FTW3 Ultra Gaming series. Designed for AI workloads—Ollama, Stable Diffusion, and local LLM inference—this block directly contacts the 24GB GDDR6X modules that reference air coolers leave exposed, eliminating the notorious 92°C VRAM throttle that cripples sustained inference performance.
Silence is mandatory for home AI labs. Stock FTW3 fans scream at 45–65 dBA during 350W inference loads; liquid cooling drops operation below 30 dBA, enabling 24/7 bedroom or office deployment without acoustic fatigue. VRAM protection is equally critical: GDDR6X junction temperatures hit 104–110°C on air, degrading memory modules over time. This block's direct-die cold plate and dedicated VRAM channels maintain sub-70°C sustained temps, preserving your 24GB investment.
Used GPU revival transforms degraded previously-deployed 3090s. Two-to-four-year-old cards suffer thermal pad hardening and paste pump-out; installing this block performs a complete thermal reset, restoring full boost clocks for AI duty. For multi-GPU necessity, dual 3090s (700–900W combined) physically cannot be air-cooled in a single case—water cooling is the only viable path. 24/7 reliability demands sustained thermal headroom that air simply cannot provide during multi-hour training runs or persistent inference servers.
Nickel-plated copper cold plate, G1/4 standard threading, integrated aluminum backplate for rear VRAM cooling. Ships worldwide.
Frequently Asked Questions
Is this waterblock compatible with my RTX 3090?
This Bykski waterblock is designed for the RTX 3090. 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 3090 be with water cooling?
Stock RTX 3090 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 350W 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 3090?
- Thermal pads on 2-4 year old used 3090s are degraded; installing a waterblock = complete thermal reset, revives ex-mining/ex-gaming cards for AI duty
- 350W sustained for 24/7 Ollama inference = 55 dBA fan noise from the triple-fan FE cooler — unacceptable for home office/bedroom
- Dual-3090 builds (700W total GPU) are the cheapest path to 48GB VRAM for 70B LLMs — water cooling is the only way to fit both in a normal case
- #1 target for FormulaMod — the largest used-GPU waterblock upgrade market in existence
Full-cover water blocks cool GPU die + VRAM + VRM simultaneously — unlike air coolers that only target the GPU die.
