BitsPower Orion dissipador de água para GPU para RTX 4090 FE – Tampa superior em acrílico (BP-VG4090FE-SOLO)

BitsPower Orion GPU water block for the NVIDIA RTX 4090 Founders Edition is a full-cover liquid cooling block with an acrylic top designed to replace the stock air cooler. It provides a direct thermal interface between the GPU die, VRAM and power delivery components and the coolant, allowing efficient heat transfer into a custom liquid cooling loop. The block is intended for high-end gaming and workstation builds where lower GPU temperatures and reduced acoustic noise are required for sustained performance.

Advantages

The acrylic-top construction offers clear visibility of coolant flow and channel layout while maintaining a durable contact surface. Full-coverage design ensures even cooling across the GPU die, memory modules and VRM area, helping to lower peak temperatures. The block is engineered to integrate with standard G1/4 fittings and common mounting patterns for straightforward installation in compatible RTX 4090 Founders Edition cards. Using a dedicated GPU water block can reduce fan noise compared with air cooling and support longer periods of high load without thermal throttling.

Suitable for

• Custom liquid-cooled gaming PCs using NVIDIA RTX 4090 Founders Edition
• High-performance workstation builds requiring stable GPU temperatures under sustained load
• Silent PC projects focused on minimizing fan noise
• Overclocking setups where improved cooling is needed for higher sustained clock speeds

Key specifications

• Compatibility: specifically designed for NVIDIA RTX 4090 Founders Edition full-cover fit
• Top material: acrylic window for coolant visibility
• Cold plate material: high-conductivity metal contacting GPU and adjacent components
• Fittings: standard thread size compatible with common liquid cooling fittings
• Cooling coverage: GPU die, memory modules and power delivery area

How to use

Prepare the graphics card by removing the original cooler according to the manufacturer’s service instructions and cleaning thermal residue from the GPU die, memory modules and VRM surfaces. Apply an appropriate thermal interface material to the GPU die and, where applicable, to memory and power components following supplier recommendations. Align the BitsPower Orion water block with the card’s mounting points and secure it using the provided hardware, ensuring even pressure on the cold plate. Connect inlet and outlet fittings to your loop, fill and bleed the cooling system, and verify there are no leaks before powering the PC.

Recommendations

The block is intended for use in a closed-loop liquid cooling system with compatible fittings and coolant. Use recommended coolant types to avoid corrosion or clogging, periodically inspect fittings and seals for leaks, and monitor coolant temperature and flow rate. Ensure proper case airflow for other components and follow GPU manufacturer guidelines when handling the card and removing factory coolers.
