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.
