Bloque radiador Aqua-Computer 33701 — aluminio/cobre/acero inoxidable, 160×140×40 mm, plata

Aqua-Computer 33701 radiator block is a compact liquid-cooling component for custom PC cooling loops, finished in silver and constructed from aluminium, copper and stainless steel. With physical dimensions of 160 × 140 × 40 mm, the unit is designed to transfer thermal energy from coolant to radiator elements within desktop and small form-factor systems. The block's materials ensure direct coolant contact only with seals, Delrin, copper and stainless steel, while the silver finish provides a neutral appearance suitable for a wide range of builds.

Advantages

The radiator block uses a multi-material construction that balances thermal conductivity and corrosion resistance by combining copper, aluminium and stainless steel where appropriate. Manufacturing omits welding inside coolant channels to avoid welding residues and preserve internal cleanliness. Threaded nickel-plated brass inserts are integrated for easier fan alignment and deeper threads, which reduces the risk of damaging fins or tubes when mounting fans. The compact overall size offers high fin-area efficiency for its footprint, making it practical for builds with limited space.

Suitable for

• Custom liquid-cooling loops in desktop PCs
• Small form-factor and compact cases requiring efficient cooling components
• Systems where reliable material compatibility and corrosion control are priorities
• Builds that need precise fan alignment during radiator installation

Key specifications

• Construction materials: aluminium, copper, stainless steel (coolant contact limited to seals, Delrin, copper and stainless steel)
• Finish: silver
• External dimensions: 160 × 140 × 40 mm
• Design: no internal welding in coolant passages
• Mounting: threaded nickel-plated brass inserts for fan alignment (inserts included for one side; additional inserts available separately)
• Frame material and appearance: stainless steel frame with dark gray chromated rear

How to use

Install the radiator block into the PC chassis at an appropriate location for airflow and loop routing. Attach fans using the supplied threaded inserts; if installing without fans, install the inserts upside-down to achieve a near-flat surface against the case. Integrate the block into the cooling loop using compatible fittings and tubing, ensuring seals and connections are tight and leak-free. Follow standard liquid-cooling practices: purge air from the loop, verify flow, and monitor temperatures during initial operation.

Recommendations

Use corrosion-inhibiting coolant and follow the coolant manufacturer's compatibility guidance to preserve materials and seals. When mounting fans, use screws of appropriate length to avoid contacting fins or tubes. If additional inserts are needed for both sides, obtain matching nickel-plated brass inserts to maintain alignment and thread depth. Perform routine checks for leaks and coolant condition as part of regular system maintenance.
