Heatsink Alphacool 14227

The Alphacool 14227 heatsink is part of the NexXxos radiator family designed for water-cooling loops. Constructed with copper main parts and precision fins, this 45 mm-thick heat exchanger offers improved thermal transfer and compatibility with a variety of fan sizes. Its compact dimensions (92 mm width × 229 mm depth × 45 mm height) and flat chamber design increase mounting flexibility and make installation possible in tighter enclosures. The unit is finished in black and sold as a single heatsink compatible with standard M3 fan and grill mounts.

Advantages

All primary components of this NexXxos model are copper, including chambers, fins and channels, which increases thermal conductivity compared with mixed-metal designs. Separated internal chambers guide coolant flow to allow high flow rates without performance loss. Flat chambers reduce overall length and improve compatibility with constrained spaces. Standard M3 threaded mounts and an internal protective ledge prevent damage from over-inserted screws. The fin geometry is optimized to perform well with low to medium fan speeds, enabling quieter operation and a wider choice of compatible fans.

Suitable for

• Custom liquid-cooling loops in desktop PCs
• Small or compact cases where radiator depth is limited
• Systems requiring quiet operation with low-to-medium fan speeds
• Setups using 120 mm, 140 mm or 180 mm fan configurations (depending on model)

How to use

Install the heatsink into your water-cooling loop using the appropriate fan size and mounting screws that match the M3 threads. Position the radiator so coolant inlet and outlet align with your loop routing; the flat-chamber design allows tight placement inside constrained cases. Use the 1/4" threaded opening (on compatible NexXxos models) for de-aeration or filling if required, or pair with a Fillport for convenient top-up. Ensure fans are mounted correctly and screws are not overtightened—the internal protective ledge prevents fin damage if a screw is inserted too far.

Recommendations

For optimal performance, pair the Alphacool 14227 with low-to-medium speed fans to balance airflow and noise. Maintain good loop flow by using the separated-chamber routing and periodically bleed air through the provided threaded port when filling or servicing the loop.
