RAD240C Copper Water Cooling Radiator 240mm Slim Dual - Low Resistance

In this review the RAD240C Copper Water Cooling Radiator is examined for compact custom loops where space and thermal efficiency matter. The bottom line: this 240mm slim dual radiator is aimed at builders who need a low-profile, high-conductivity solution - its 20 FPI copper fin array and dual-pass, 14-tube layout prioritize heat transfer while keeping a shallow 28mm thickness to fit tight mounts. The review focuses on real installation considerations, expected cooling behavior, and the physical features that make it a sensible choice for compact or constrained PC builds.

Key Features

• Slim 28mm profile: Enables mounting in narrow cases or top-clearance positions and reduces air flow resistance for quieter fan setups.
• 20 FPI copper fins: Provide high thermal conductivity and a large heat transfer surface area to move heat away from coolant quickly.
• Dual-pass 14-tube design: Offers high flow with low pressure drop, balancing flow rate and cooling surface for efficient loop performance.
• G1/4 threaded ports: Ensure broad compatibility with common fittings and easy integration into existing water-cooling loops.
• Included mounting hardware: Comes with M3 screws for both fan mounting and chassis attachment, simplifying installation of two 120mm fans.

Who It's For

The RAD240C suits PC builders who assemble compact custom loops or upgrade small form-factor systems and need a 240mm radiator that will fit where thicker radiators cannot. It is particularly useful for users pairing slim 120mm fans to reduce stack height or for top-mount placements with limited clearance.

Builders who require extreme overclock cooling headroom or prefer very dense fin counts for push-pull configurations might look elsewhere; this model balances conductivity and low resistance rather than maximizing fin density for static-pressure fans.

Pros & Cons

Pros

• High-conductivity copper fins give efficient heat transfer without excessive thickness.
• Slim 28mm thickness reduces airflow resistance and helps in cramped case layouts.
• G1/4 ports and included screws make integration with common fittings and 120mm fans straightforward.

Cons

• Slim profile limits total fin volume compared with thicker radiators, so absolute thermal capacity is moderate.
• Rated to 1 bar (14 psi), which is adequate for most loops but should be noted by builders using unusual high-pressure pumps.

Our Verdict

The RAD240C is a practical, value-minded 240mm radiator for compact custom loops where clearance and low airflow resistance are priorities. Its copper 20 FPI fin stack and 14-tube dual-pass design deliver efficient heat transfer without the bulk of thick radiators, making it a smart pick for small form-factor builds and quiet setups that pair slim 120mm fans.

Frequently Asked Questions

Will it fit in slim top-mount locations?
The 28mm thickness is designed for tight top-mount or constrained side-mount spots and will fit many cases that cannot accept thicker radiators.

Which fittings work with the ports?
The G1/4 threaded ports accept most standard water-cooling fittings used in consumer custom loops.

Are fans included?
No fans are included; the radiator ships with M3 screws for mounting two 120mm x 25mm fans such as typical slim or standard duty models.
