Zalman ALPHA2 A36 White ARGB AIO Liquid CPU Cooler, AM5/LGA1851
The Zalman ALPHA2 A36 White is an all-in-one liquid CPU cooler for Intel LGA1851/1700/1200/115X and AMD AM5/AM4 builds, finished in white with addressable RGB lighting. Its 397mm aluminium radiator, copper-base pump and PWM-controlled 120mm fans suit gamers who want strong, quiet cooling and a live CPU temperature readout on the pump head.
Key features
- Live CPU temperature display: the pump head shows real-time CPU temperature pulled from the BIOS, so you can check thermals at a glance.
- Broad socket support: fits Intel LGA1851/1700/1200/115X and AMD AM5/AM4, so it suits current and previous-generation platforms.
- Dual flow-path pump with pure copper base: separate inflow and discharge paths help prevent pump overload while the copper base draws heat from the CPU.
- Zalman AF120 fans with shark-fin blades: PWM control from 600 to 2,000 RPM with a maximum of 29.7 dB(A) for low-noise operation.
- 360° rotatable magnetic pump head and ARGB sync: keep the logo upright in any orientation and sync lighting with your motherboard's RGB software.
