Bykski I-GNA700TF-SR graphics card water block with all-metal construction, designed for Intel A770 16G Card graphics cards.
This product is compatible with GUNNIR Intel Arc A770 16G Graphics Card
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 15565.2954mm².The copper plate length has been extended to 196mm to increase the water flow coverage area.
Why Water Cool the RTX 5090?
575WTDP under AI load
32GBVRAM (throttles at 92°C)
<30dBWith 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.
