Primochill CTR reservoirs are designed with the modder in mind. It has the intriguing innovation of compression end-caps, the flexibility of a multi-options setup, and outstanding precision craftsmanship. However, it is still not perfect. There are some areas which raised our concern: the end-caps have four stainless mounting screws which are exposed to the coolant. This future potential galvanizes corrosion deposit. The second is the vortex of the coolant; if the liquid is the glycol base then the vortex generates a lot of air bubbles in the reservoir.
Unfortunately, Primochill chooses not to include the anti-vortex (Zen Coil), bit it is instead available as an optional add-on. Our third issue is the CTR has 6x G1/4” ports. The common setup only occupied up to 3 ports but no port-plugs are included. Additionally, the compression end-caps aren’t suitable for direct pump mounting since the ports are off center. Our final issue is the 3mm acrylic mounting brackets. They do their job but we prefer a POM (or the flexible metal strap) over the acrylic material.
The CTR carries a price tag of $52.95, backed by a limited 6 months conditions warranty.
Use of caustic coolant will void your warranty and cause your reservoir to crack.
The price seems normal for a 240mm tube reservoir, but purchasing the extra 4 port-plugs and the Zen-coil will set you back another $16 – $20. That’s about $10 higher than the EK-Multioption X3-250mm reservoir which already has almost all of these accessories.
All that being said; we give the CTR a thumbs up for the innovation design of the compression end-caps. It’s flexible, and if Primochill can address the above mentioned areas, then the CTR will be a kick-ass reservoir. For now it earns the PureOverclock Good Hardware award.
