Alphacool Eisdecke Dual D5 Pump Top, Brass, Deep Black
Designed to fit two Alphacool eispumpe pumps (VPP755 or VPP655) and compatible with other D5/PWM pumps, this brass top provides robust mounting options. It supports both vertical and horizontal configurations, including 45-degree and 90-degree angles, and offers three 1/4″ inlet and three 1/4″ outlet ports for flexible loop routing. Best for builders seeking a high-strength, multi-angle mounting solution for dual-pump layouts. Limitation: brass construction can be heavier and requires careful handling during installation.
YQQEWI 1pcs Reservoir For Double D5 Pump (No Armor)
This reservoir is designed for a dual D5 pump setup without armor. It provides a compact reservoir solution with two G1/4″ ports for inlet and outlet lines. Best for compact builds where armor is not required and where the user prioritizes straightforward integration. Caution: ensure compatible pump mounting hardware for secure dual-pump installation.
GHHSBO Reservoir For Double D5 Pump (Tank No Armor)
Similar to the Armor-free variant, this reservoir supports a dual D5 pump arrangement with dual G1/4″ ports. Best for users who want a straightforward, armor-free reservoir in a dual-pump loop. Limitation: armor options may be needed for extra protection or style in some builds.
GHHSBO Reservoir For Double D5 Pump (Tank No Armor)
Another no-armor option for a double D5 pump setup, featuring dual G1/4″ ports. Best for users who want a simple, functional reservoir without protective armor. Consider compatibility with your pump tops and mounting hardware before purchasing.
Stealkey Customs ResPro 95 D5/DDC Reservoir
Built for versatile PC water cooling, the ResPro 95 supports both D5 and DDC pumps, with five G1/4″ ports for varied configurations. Best for users who want a flexible, multi-port reservoir that can adapt to different pump types. Limitation: multi-port layouts require careful planning to avoid flow bottlenecks or air traps.
YQQEWI POM Reservoir For Single D5 Pump
Single-pump POM reservoir options provide two G1/4″ ports for inlet and outlet, suitable for compact single-pump loops that may later expand to dual-pump configurations. Best for smaller builds or upgrades where space is a priority. Caution: not ideal for immediate dual-pump setups without additional hardware.
YQQEWI POM Reservoir For Single D5 Pump (Armor)
This armor-equipped reservoir variant adds protective covering while maintaining the dual-port configuration. Best for users who want a dual-pump-ready reservoir with extra durability, though armor adds size and weight. Avoid if space is extremely tight.
Buying Guide: Dual D5 Pump Reservoirs
Key considerations when selecting a dual D5 pump reservoir system include pump compatibility, port configuration, mounting versatility, and future expandability. If you plan to run two pumps, prioritize reservoirs and tops that support multi-angle mounting and ample G1/4″ ports for easy tubing routing. For compact builds, choose armor-free, space-conscious designs with minimal height. If you may upgrade to different pump types (D5 or DDC), select a versatile reservoir like the Stealkey ResPro 95 that handles both pump families and offers multiple ports for expansion.
Buying considerations at a glance
- Port count and layout: ensure sufficient G1/4″ inlets/outlets for your loop routing.
- Mounting flexibility: look for vertical, horizontal, and angled mounting options.
- Armor presence: armor can protect the reservoir but increases size and weight.
- Material choice: brass and POM variants offer durability and chemical compatibility considerations.
- Pump compatibility: confirm the reservoir/top works with your specific D5 or D5-compatible pumps.
FAQ
- What is a dual D5 pump reservoir best for?
It’s ideal for high-flow custom cooling loops needing redundancy or increased cooling capacity. - Do I need armor on my reservoir?
Armor adds protection and style, but is optional depending on space and build aesthetics. - Can I mix pump brands with a dual D5 reservoir?
Yes, some reservoirs are designed for cross-brand compatibility, but always verify port sizing and mounting compatibility first. - Which reservoir is best for compact builds?
