120 mm · 40 mm Thick · Full CopperOC-CRD12 120mm Copper Radiator
160 × 120 × 40 mm · Dual-Pass · 2× G1/4″ · 12 Channels
A short 160 mm copper core for ITX and SFF builds, 40 mm thick so it still has real fin area, with both ports on the same end face.

Please read before ordering:
- Overall length is 160 mm, not 155 mm.It is longer than many 120 mm radiators, because the end tank sits proud of the core. Measure your case mount before ordering.
- Both ports face forward from the end tank.Fittings and tubing will extend roughly 30–40 mm beyond that face — allow for it in tight ITX builds.
- Only 4 long fan screws are included.That covers one 25 mm fan. For push-pull with two fans you need 4 more #6-32 × 31 mm screws, which are not in the box.
- There is no dedicated bleed port.Both ports share the same end tank for dual-pass flow; air is bled from the highest point of your loop, normally the reservoir.
- Fan, fittings, tubing and coolant areNOT included.

40 mm of core in a 120 mm frame gives this radiator enough surface to matter in a small loop.Lead-Free Copper
Copper core with lead-free brazing, avoiding the mixed-metal corrosion you get pairing copper blocks with aluminium radiators.12 Waterways, Dual-Pass

FAQ
Why is it 160 mm and not 155 mm?
The end tank and port boss sit proud of the core, so the end-to-end length is 160 mm. Check the mount opening in your case rather than assuming a standard 120 mm radiator length.
Can I use either port as inlet?
Yes. Both ports open into the same end tank on a dual-pass core, so either can be inlet or outlet.
Where do I bleed the loop?
At the highest point of the system, normally the reservoir. This radiator has no separate bleed port.
Is a fan included?
No. One 120 mm fan is supported, two in push-pull, but fans are not part of the package.
