Zalman CNPS9X Optima2 ARGB CPU Cooler AM4/AM5/LGA1200/1700

The Zalman CNPS9X OPTIMA2 is a compact CPU air cooler designed for desktop PCs. It combines a heatsink with multiple heat pipes and a 120 mm PWM‑controlled fan to deliver effective cooling up to around 190 W TDP. Its modest size and broad socket compatibility make it suitable for a variety of mainstream Intel and AMD builds where straightforward cooling and reliable airflow are required. Compact CPU cooler with modest footprint suited for standard desktop cases. Heatsink constructed from pure copper and pure aluminium for efficient heat dissipation. Four heat pipes to transfer CPU heat to the fins for cooling. Cooling capacity rated up to 190 W — sufficient for most mid‑range CPUs. 120 mm hydraulic‑bearing fan with PWM fan‑speed control for balanced airflow and noise. Fan speed ranges from 800 to 1,500 RPM (±10%), enabling quiet operation at low loads and stronger airflow under load. Relatively low maximum noise level (~29.5 dB(A) ±10%) — suitable for quiet or semi‑silent builds. Wide CPU socket compatibility including recent Intel and AMD desktop and workstation sockets. 24 Month Return to Base Warranty Model name Zalman CNPS9X OPTIMA2 Cooler type Air cooler with copper/aluminium heatsink fan Heatsink materials Pure copper and pure aluminium Dimensions (heatsink fan) 120 × 75 × 155 mm (H) Weight 635 g Heat dissipation area 5,974 cm² Number of heat pipes 4 Cooling capacity (Q’Max) 190 W Fan dimensions 120 × 120 × 25 mm Fan bearing type Hydraulic bearing Fan speed 800 – 1,500 RPM ±10% (PWM controlled) Maximum fan airflow ≈ 47.12 CFM ±10% Maximum fan noise ≈ 29.5 dB(A) ±10% Maximum static pressure ≈ 1.06 mmH₂O ±10% Fan connector type / control 4‑pin PWM Rated fan voltage / current / power 12 V DC (LED 5 V), 0.31 A, 3.72 W Supported CPU sockets (Intel) LGA 1851 / 1700 / 1200 / 115X / 2066 / 2011‑V3 / 2011 Supported CPU sockets (AMD) AM5 / AM4 / AM3
