Is this waterblock compatible with my RTX 3090?

This Bykski waterblock is designed for the RTX 3090. Please check the product title for specific card brand compatibility (ASUS, MSI, Gigabyte, etc.) as non-reference PCB designs require model-specific blocks. If you are unsure of your card's PCB variant, contact FormulaMod support at customermanager@formulamod.net before ordering.

Will this reduce noise on my RTX 3090 during AI workloads?

Yes. Stock RTX 3090 air coolers run at 45-65 dBA under sustained AI inference loads (Ollama, Stable Diffusion, ComfyUI). A full-cover waterblock like this mounted to a 360mm radiator typically reduces noise to under 30 dBA while also lowering VRAM temperatures from 90°C+ to 60-70°C, preventing throttling during long generation runs.

What else do I need for a complete water cooling loop?

A complete custom loop requires: this GPU waterblock, a radiator (360mm recommended for single GPU, 480mm for GPU+CPU), a D5 or DDC pump with reservoir combo, G1/4 fittings, tubing, and premixed coolant. FormulaMod sells complete kits starting at $249 USD including pump, radiator, and fittings.

Does this waterblock cover the VRAM and VRM chips?

Full-cover waterblocks cool the GPU die, VRAM modules, and VRM components simultaneously via a single block with an integrated cold plate. This is essential for AI workloads where sustained 100% VRAM utilization can cause memory junction temperatures to exceed 110°C on air cooling. The full-cover design distributes coolant flow across the entire PCB thermal zone.

Why Water Cool the RTX 3090?

350W TDP under AI load

24GB VRAM (throttles at 92°C)

<30dB With water cooling

- CRITICAL: backside GDDR6X memory modules have no heatsink contact on reference PCB — junction temps hit 104-110°C under sustained load, the root cause of the infamous '3090 VRAM throttle at 92°C' — full-cover waterblocks directly resolve this
- 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.
