ZALMAN today launched the Alpha line of all-in-one liquid CPU coolers. Available in three variants based on radiator size—Alpha 36 (360 mm x 120 mm), Alpha 28 (280 mm x 140 mm), and Alpha 24 (240 mm x 120 mm), each with sub-variants based on color—white and black; the main sell with the Alpha series is an innovation with the pump-block design.

ZALMAN designed the pump to feature three independent coolant flow paths for the inflow and outflow, which works to prevent pump overload. Its designers claim this also improves cooling performance by reducing residual fluid in the pump-chamber. The heat-dissipation base is made of copper, with a large micro-fin lattice, with 0.15 mm fins. The pump-block features an in-built fan-controller that manages the radiator fans based on cooling needs. The pump-block also features a dome-shaped ARGB-illuminated top that freely moves around, so you can orient the ZALMAN logo whichever way you want.

Each of the 120 mm fans included with the Alpha 36 and Alpha 24, turn between 500 to 1,800 RPM, with 1.90 mm H₂O static pressure, and 33 dBA maximum noise, while the 140 mm fans included with the Alpha 28 turn at 500 to 1,600 RPM, with 1.70 mm H₂O static-pressure, and 34 dBA maximum noise. The company didn't reveal flow-rate. Among the CPU socket types supported by all models include LGA1700, AM4, and LGA1200. The company didn't reveal pricing.

If it will beat current AIO list - great product.

If it fails in performance -> When RGB is more important than performance - Zalman 2022.
