The Bykski N-GV3090AORUSXE-TC-V2 is a full-cover GPU water block with active waterway backplane cooler engineered specifically for the Gigabyte Aorus RTX 3090, 3080 Ti, and 3080 Xtreme. This block directly addresses the RTX 3090's critical thermal flaw: backside GDDR6X modules on reference PCBs have zero heatsink contact, pushing junction temperatures to 104-110°C under sustained LLM inference loads and triggering hard throttling at 92°C.
VRAM PROTECTION is immediate and absolute. The integrated backplane waterway presses liquid-cooled copper directly against those rear memory modules, eliminating the thermal barrier that stock coolers cannot cross. For USED GPU REVIVAL, this block replaces degraded 2-4 year old thermal pads with fresh, high-conductivity interfaces—transforming ex-mining or ex-gaming 3090s into thermally reset AI workhorses ready for 24/7 duty.
SILENCE matters when your AI rig runs in a home office or bedroom. Stock fans scream at 45-65 dBA during sustained inference; this water block drops operation below 30 dBA. 24/7 RELIABILITY demands sustained thermal headroom—Ollama, Stable Diffusion, and local LLMs run for hours or days, not minutes. MULTI-GPU NECESSITY is unavoidable: dual RTX 3090s pull 700-900W combined, and no air solution physically fits or thermally manages that density in a single case.
Nickel-plated copper construction. G1/4 threading. Includes active backplane cooler and backplate. 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.
