Is this waterblock compatible with my RTX 5080?

This Bykski waterblock is designed for the RTX 5080. 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 5080 during AI workloads?

Yes. Stock RTX 5080 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 CPU-4710-SR LGA4710/4677 Vacuum Brazed CPU Water-Cooled Head Server Workstation

The CPU-4710-SR uses a T2 copper base plate with a high thermal conductivity of 401W/m·k, enhancing its thermal performance. It is vacuum-brazed into a single piece, with the upper and lower plates joined by solder paste, resulting in a tight, leak-free structure that ensures long-term stable heat conduction and withstands installation pressure. The 0.35mm thick copper base effectively reduces the copper plate's thermal resistance, improving thermal conductivity.

Why Water Cool the RTX 5080?

360W TDP under AI load

16GB VRAM (throttles at 92°C)

<30dB With water cooling

- 360W sustained for AI inference = persistent 45+ dBA fan noise
- Blackwell dual-fan FE cooler still struggles with 24/7 workloads
- Single-slot water cooling enables packing 2x 5080 in mid-tower cases

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