Computer case fan INTER-TECH ES-011, 120 mm, black, 1 pc

The ES-011 is a 120 mm case fan designed for easy installation and tidy cable management. It combines PWM speed control with addressable RGB (A-RGB) lighting and is suitable for most PC cases that accept 120 mm fans. Its compact dimensions and standard mounting make it a practical choice for system cooling in desktop and gaming towers.

Advantages

The fan supports daisy-chaining: multiple ES-011 units can be connected one after another using integrated plug contacts so that power and A-RGB signal pass from fan to fan. This eliminates the need for multiple cables and reduces clutter, which is useful when installing several fans in a row. PWM control allows speed regulation according to system temperature or motherboard settings.

Key specifications

• Type: Computer case fan, 120 mm
• Airflow: 127 CFM
• Dimensions: 120 x 120 x 25 mm; Weight: 140 g
• Color: Black
• Package contents: 1 pc

How to use

Mount the ES-011 into a standard 120 mm fan slot in your case using the supplied screws or existing mounting hardware. Connect the first fan to the motherboard or fan controller for PWM and A-RGB control. If installing additional ES-011 fans, use the integrated plug contacts to daisy-chain them, so only the first fan requires a direct cable connection. Configure fan curves and lighting in your motherboard software or compatible controller.

Recommendations

For optimal performance, install the fans so that airflow direction matches your case’s intake and exhaust layout. Use motherboard or controller settings to balance noise and cooling according to system load. When daisy-chaining multiple fans, ensure the combined power draw does not exceed the header or controller limits specified by your motherboard or controller manufacturer.
