Description
The Bitspower NEBULA VGA Water Block (BPM-VG5090AST) is a precision-engineered cooling solution designed specifically for the ASUS TUF Gaming GeForce RTX 5090. By replacing the stock air cooler with a full-coverage liquid cooling block, users can significantly reduce operating temperatures while maintaining a slim profile. The block features a CNC-machined copper base plated in nickel and chromium for enhanced corrosion resistance and optimal heat transfer across critical power delivery components.
This product is for:
- PC Enthusiasts seeking to maximize the thermal headroom of the NVIDIA Blackwell architecture.
- Custom Loop Builders looking for a sleek, transparent aesthetic with synchronized Digital RGB lighting.
- Professional Workstation Users requiring consistent clock speeds and reduced noise levels during heavy rendering tasks.
- Small Form Factor (SFF) Builders who need to reduce the physical footprint of the massive RTX 5090 air cooler.
- Competitive Overclockers aiming for lower delta temperatures to achieve higher stable frequencies on the TUF Gaming PCB.

Installing the NEBULA block transforms the ASUS TUF 5090 into a streamlined powerhouse. The pre-applied thermal pads simplify the assembly process, ensuring that the VRM and VRAM contact points are perfectly aligned with the micro-channel structure of the cold plate. In operation, the clear acrylic top allows for a direct view of the coolant flow, while the integrated LED strip provides vibrant, customizable illumination compatible with major motherboard ecosystems like ASUS Aura Sync and Razer Chroma. The included backplate not only reinforces the PCB but also features a contoured design to dissipate heat from the rear-mounted components.
Compared to standard universal water blocks, the Bitspower NEBULA is a bespoke solution tailored to the specific component layout of the ASUS TUF Gaming RTX 5090 PCB. While the factory air cooler occupies nearly four slots and relies on high-RPM fans, this water block reduces the card's thickness to approximately 30.2mm and eliminates fan noise entirely when integrated into a liquid loop. Its chromium-plated finish offers superior durability compared to bare copper alternatives, preventing oxidation over long-term use.
Q&A:
