Product details

The Zalman ALPHA28 CPU liquid cooler features a 280 mm radiator with two 140 mm addressable RGB fans and is designed for efficient thermal management in computer systems. This black cooling solution integrates an innovative triple water flow pump design that separates the coolant inlet and outlet into three distinct paths to minimize residual liquid and enhance cooling performance. The pump operates at 3,200 RPM, utilizes ceramic bearings, and delivers a water flow rate of 0.83 L per minute. The aluminum radiator measures 140 x 316 x 27 mm with heat dissipation fins designed for optimal airflow, while the two 140 mm fans feature durable bearings, adjustable speeds from 500 to 1,600 RPM, and maximum noise levels of 34 dB(A). The spherical pump housing design includes addressable RGB lighting effects that can be synchronized with compatible motherboard RGB controllers via 3-pin 5V RGB SYNC connectors, and an included ARGB controller allows for adjustments without motherboard RGB connections. The water block housing can be rotated 360 degrees for flexible tubing routing and logo orientation. Anti-vibration rubber pads reduce operational noise, and the package includes high-quality thermal paste. It is compatible with Intel LGA 2066, 2011-V3, 2011, 1700, 1200, and 115X sockets as well as AMD AM4 and AM3 sockets. The pump dimensions are 68 x 68 x 62 mm, made from ABS, PC, PPS, and pure copper. Each fan measures 140 x 140 x 25 mm with a maximum air pressure of 1.7 mm H₂O. The radiator supports push-pull configurations for optimal airflow, and mounting holes on both sides facilitate installation.
