Ventilátor do počítačové skříně Chieftec AF-1225S černý

The Chieftec AF-1225S is an original CHIEFTEC 120 mm case fan designed to improve air circulation inside computer chassis. It comes in black, features a sleeve bearing and includes the fan, a set of mounting screws and the necessary connector cables for installation.

Advantages

The fan operates at 12 V and provides up to 55 CFM airflow at a maximum speed of 1650 RPM while producing a noise level of 28 dB. It includes a 3‑pin motherboard connector with an additional speed‑sensor wire and a standard Molex connector for flexible power options. The compact 120 x 120 x 25 mm size ensures compatibility with most PC cases.

Suitable for

• General computer case cooling
• Replacing or upgrading existing 120 mm fans
• Systems requiring moderate airflow with low noise

Key specifications

How to use

Mount the fan into a compatible 120 mm fan slot in your PC case using the supplied screws. Connect the 3‑pin connector to a motherboard fan header to enable speed monitoring, or use the Molex connector for direct power from the PSU if a motherboard header is not available. Ensure airflow direction aligns with your case cooling plan (intake or exhaust) and secure cables to avoid interference with other components.

Recommendations

For sustained quiet operation, install the fan on a clean, dust‑free chassis and check bearing condition periodically. Replace the fan if abnormal noise or reduced airflow occurs. Use the motherboard header for RPM monitoring where possible.
