Is this waterblock compatible with my RTX 5090?

This Bykski waterblock is designed for the RTX 5090. 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 5090 during AI workloads?

Yes. Stock RTX 5090 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.

Bykski N-TESLA-A100-80G-SR graphics card water block, all-metal structure, TESLA A100 80G

This product is compatible with NVIDIA TESLA A100 80GB and NVIDIA TESLA A8O0 8OGB

0.3mm jet-type micro-channels increase the heat absorption area, resulting in powerful heat dissipation performance. Furthermore, it features up to 56 channels, increasing the channel area to 12398.8635mm².The copper plate length has been extended to185.5mm to increase the water flow coverage area.

Why Water Cool the RTX 5090?

575W TDP under AI load

32GB VRAM (throttles at 92°C)

<30dB With water cooling

- 575W TDP is the highest ever in a consumer GPU — stock triple-fan coolers hit 55+ dBA under sustained AI load, unusable in home office
- 32GB GDDR7 runs hot at full utilization; waterblocks with full VRAM coverage prevent throttling during long inference sessions
- Dual-5090 AI workstation (1150W GPU power) is only physically buildable with water cooling — air coolers are too thick

Full-cover water blocks cool GPU die + VRAM + VRM simultaneously — unlike air coolers that only target the GPU die.
