Reservoir Alphacool Core 140mm VPP/D5 14577 — reservoir for D5 pump, 140 mm fan-compatible

Alphacool Core 140mm VPP/D5 14577 is a liquid cooling reservoir engineered for integration with D5 (VPP) pumps and designed to occupy a standard 140 mm fan bay. The reservoir provides a compact, fan-compatible solution that simplifies installation in systems with limited space while enabling easy filling, bleeding and visual monitoring of coolant level. Constructed to match common 140 mm mounting patterns, it supports neat pump mounting and direct connection to the rest of a custom water-cooling loop.

Advantages

The reservoir combines compatibility with D5/VPP-type pumps and 140 mm fan mounts to reduce the need for additional brackets or adapters. Its compact form factor and clear sight port streamline coolant level checks and maintenance operations. Built for integration into standard fan bays, it helps maintain a tidy internal layout and supports secure pump attachment, which contributes to stable flow and quieter operation when installed correctly.

Suitable for

• Custom PC water-cooling loops that use a D5/VPP pump and have a 140 mm fan bay available
• Systems where space is limited and a compact reservoir fitting a 140 mm mounting pattern is required
• Users who need simplified filling, bleeding and visual coolant monitoring without external reservoirs

Key specifications

• Compatibility: designed for D5 (VPP) style pumps
• Mounting: fits standard 140 mm fan mounting positions
• Form factor: compact inline reservoir suitable for internal installation
• Material and finish: transparent sight area for coolant level monitoring combined with durable housing components
• Connections: standard threaded inlet/outlet ports compatible with common water-cooling fittings

How to use

Install the reservoir into a free 140 mm fan bay using the matched mounting holes and screws, then attach the D5/VPP pump according to the pump manufacturer’s mounting instructions to ensure secure seating. Connect the inlet and outlet ports to the loop tubing with compatible fittings and ensure tubing routing allows for proper flow and minimal kinking. Fill the loop with the chosen coolant, operate the pump briefly to circulate and then top up while bleeding air from high points; repeat until no air pockets remain and the coolant level is stable. Verify all fittings are tightened and check for leaks before normal operation.

Usage recommendations

Use coolants and fittings recommended for PC liquid cooling and perform initial leak testing outside of critical components. Mount the reservoir so the pump intake remains submerged during operation and periodically inspect coolant level and condition; replace coolant according to the coolant manufacturer’s guidance to maintain performance and prevent deposits.
