  • Compression-ring end caps seal without cutting tube
  • 57 mm inner diameter supports high-flow D5 pumps
  • 120 mm mounting rings fit standard fan locations
  • Black POM end caps and D5 head installed
  • Made in the USA with included anti-vibration pads

Reservoir for custom loops

The PrimoChill CTR reservoir is a hard-mount acrylic tube designed for custom liquid-cooling builds that use a Laing D5 or PrimoChill PWM D5 pump. Compression-ring end caps create a watertight seal without cutting or tapping the tube, reducing stress on the acrylic. It suits enthusiasts who want a secure, tool-free assembly and a matte black finish.

Sustained flow behaviour

The 57 mm inner diameter and high-flow D5 pump head maintain steady coolant movement during long sessions, avoiding the pressure drop that can appear in narrower reservoirs. Low-profile port caps keep restriction minimal so the loop stays balanced when the system runs at full load for hours. The rigid 63 mm outer tube resists deformation under continuous pump pressure.

Thermals noise and power

With the pump mounted directly to the reservoir, vibration transfers to the two included rubber anti-vibration pads rather than the case, keeping operational noise low. The 205 mm overall length fits standard 120 mm fan spacing, allowing a single fan to move air across the loop without extra power draw. Black POM components absorb minimal heat, so coolant temperature stays consistent.

Questions about this item

Does the 120 mm mounting pattern need a separate bracket for the D5 pump head?

The D5 pump head is already installed and the 120 mm anti-vibration pads mount directly to the reservoir body, so no extra bracket is required.

Which fittings thread into the three low-profile ports on the end cap?

All three ports use G 1/4 thread, so any standard G 1/4 compression or barb fitting will seal directly.

Will the 57 mm inner diameter tube clear a thick 120 mm radiator mounted on the same side panel?

The reservoir’s 63 mm outer diameter sits flush against the panel, leaving the 57 mm bore clear; radiator thickness does not interfere with the tube path.
