6 Best Alternatives to the Zopsc 200mm Cylinder Reservoir (2026)

How alternatives differ from Zopsc

Zopsc 200mm Cooling Reservoir

This model shares the same 6.7-ounce weight and 200mm height as the Zopsc red version. The primary difference is the green color, which may better match specific coolant aesthetics. It retains the G1/4 threaded ports and acrylic tube construction for clear visibility. You get identical leak-proof sealing technology and vertical mounting capabilities. This option is ideal if you want the same performance and durability but prefer a green look for your loop. It does not offer additional ports or different materials, making it a direct aesthetic alternative rather than a functional upgrade. Choose this if your build requires green components to maintain a cohesive theme.

Zopsc 200mm Blue Reservoir

The blue variant maintains the 200mm height and 6.7-ounce weight of the original. It features the same G1/4 thread size and acrylic construction. The main distinction is the blue color, which suits builders seeking a cooler tone for their system. It offers the same high-capacity cooling design with a 45mm diameter tube. You receive the same reinforced glue sealing and vertical mounting support. This reservoir does not provide extra connectivity or premium materials. It is best for users who want the standard Zopsc performance but need blue components to match their aesthetic. It serves as a straightforward color swap without altering the functional specifications or mounting requirements.

greenDracaena 200mm Acrylic Reservoir

This greenDracaena reservoir differs by offering four G1/4 ports instead of the standard configuration. It maintains the 200mm height but has a wider 1.97-inch diameter, making it bulkier than the Zopsc tube. The acrylic material provides clear coolant visibility similar to the original. It is heavier and takes up more lateral space in your case. This option is best for builders who need multiple connection points for pumps or radiators without using splitters. You gain connectivity at the cost of a larger footprint. Choose this if your loop design requires direct port access rather than the simpler, slimmer profile of the Zopsc cylinder.

Anu Limen 200mm Green Acrylic Water Tank

The Anu Limen reservoir is significantly narrower at 1.77 inches in width and length compared to the Zopsc’s 45mm diameter tube. It shares the 200mm height and G1/4 thread size. The green color matches the coolant aesthetic directly. It weighs slightly more at 7.04 ounces. This compact form factor is better for tight cases where lateral space is limited. You sacrifice the larger water volume of the Zopsc for a smaller profile. It is ideal for builders prioritizing space efficiency over maximum heat dissipation capacity. Choose this if your case dimensions restrict wider components, or if you prefer a green tank that blends with your coolant color scheme.

Bitspower 480mm Slim Black Radiator

This Bitspower unit is a radiator, not a reservoir, so it serves a different function entirely. It is 480mm long and 1.97 inches thick, designed for heat exchange rather than coolant storage. It uses G1/4 threads for fitting connections. You cannot use this as a drop-in replacement for the Zopsc reservoir. It is best for builders who need additional cooling capacity in a slim form factor. It does not hold water volume or provide visibility. Choose this only if you are expanding your cooling loop with a radiator rather than replacing a reservoir. It complements a reservoir but does not replicate its storage or aesthetic role.

Alphacool NexXxoS XT45 200mm Copper Radiator

The Alphacool unit is a full copper radiator, not a reservoir. It measures 200mm in width but is significantly taller and deeper for heat exchange. It uses G1/4 threads for connections. This product is made of copper for superior thermal conductivity compared to acrylic. You cannot use it to store coolant or monitor fluid levels. It is ideal for builders who need high-performance heat dissipation in a 200mm space. It lacks the visibility and storage capacity of the Zopsc. Choose this if you are adding a radiator to your loop rather than replacing a reservoir. It serves a complementary role in cooling rather than matching the original product's function.
