Is this waterblock compatible with my RTX 4090?

This Bykski waterblock is designed for the RTX 4090. 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 4090 during AI workloads?

Yes. Stock RTX 4090 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.

Aviso de actualización del radiador de refrigeración líquida todo en uno

Todos los enfriadores líquidos todo en uno (y todos los modelos posteriores) han sido completamente actualizados. El enfriador delgado original de 27 mm ha sido descontinuado; el enfriador predeterminado es ahora el enfriador grueso de 38 mm.

El enfriador grueso actualizado ofrece una mayor área de disipación de calor y una mayor eficiencia de enfriamiento, lo que lo hace más adecuado para escenarios de alta carga sin afectar las dimensiones de instalación o la compatibilidad de la interfaz.

Why Water Cool the RTX 4090?

450W TDP under AI load

24GB VRAM (throttles at 92°C)

<30dB With water cooling

- 450W sustained AI load = 50-60 dBA from the massive triple-fan coolers — unbearable in bedroom/home office
- 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.
