Introduction
In PC water cooling, a reservoir comes in different sizes and shapes but they all have one main purpose – to contain the coolant. The reservoir doesn’t contribute to the thermal performance; however, the reservoir performs a number of important tasks. It provides an easy access point for coolant filling, allows coolant to expand and contract as it changes temperature, and provides a place for air bubbles in the liquid to escape.
It’s normal to see the reservoirs constructed from acrylic material. However, the trend has been shifted to Poloxymethylene, also known as acetal. It is an engineering thermoplastic used in precision parts that require high stiffness and excellent dimensional stability.

Today, we have an opportunity to look at the new XSPC D5 Dual Bay Reservoir. Unlike many standard reservoirs, the D5 Dual Bay Reservoir is robustly compact. It has a high capacity tank, which supports direct-mount for one D5 pump, and is constructed from thermoplastic materials.
We have the specifications coming up next. Continue reading this review on the following pages.

“We released our first product the R120 radiator in 2004, the following year we released our X20 CPU waterblock, pump and watercooling kit. Since then we have released many award winning products covering all components of wtercooling systems, most recently our RX360 full cover GPU water blocks. All our products are designed for the PC enthusiast market where they are used by gamers and PC modders. Over the past year our products have been proved very popular with boutique PC manufactures and in specialist areas like recording studio PC’s. We are constantly revising our products to improve performance.”
