Zalman ALPHA2 DS A24 240mm White AIO Liquid CPU Cooler

For builders who want strong cooling without the bulk of a 360 mm radiator, the Zalman ALPHA2 DS A24 packs a 240 mm aluminium core into a clean white shell. Two 120 mm ARGB fans and a copper cold plate move heat away from modern CPUs, while the addressable lighting on both fans and pump gives your build a unified look.

Highlights

• 240 mm aluminium radiator with dual 120 mm ARGB PWM fans
• Copper base plate for efficient heat transfer from CPU to coolant
• Pump speed up to 2800 RPM with low noise operation
• Addressable RGB lighting on fans and pump, compatible with 5V 3-pin headers
• Supports Intel LGA1700, LGA1200, LGA115X and AMD AM5, AM4, AM3+, FM2+
• 400 mm tubing for flexible installation in most mid-tower cases

In daily use

The ALPHA2 DS A24 balances thermal performance with acoustics. Fan speeds range from 800 to 2000 RPM, pushing up to 71.2 CFM of air at a maximum static pressure of 2.1 mmH2O. At full load, fan noise peaks at 29.7 dB(A), while the pump stays quieter at 20 dB(A). PWM control lets your motherboard adjust fan speed based on CPU temperature, so the cooler stays quiet during light tasks and ramps up only when needed. The white finish matches white-themed builds, and the ARGB lighting can be synchronised with compatible motherboards for a cohesive look.
