120mm 12V DC 4-Pin PC Cooling Fan with Blue Light and Oil Seal Bearing

This 120mm PC cooling fan, model CJ530061, is a standard-size case fan intended for desktop computer cooling and general airflow management. It operates on 12V DC at 0.15A and 2.52W, both with a ±10% tolerance, and spins at 1100 RPM ±10%. The fan provides 22.84 CFM of airflow and 1.78 mmH2O of air pressure, which is suitable for moving air through a computer case. Its 120x120x25mm dimensions match common 120mm fan mounting points. The unit uses an oil seal bearing rated for 30,000 hours, has a 22 dB-A noise level, a 30cm cable and a 4-pin connector. Colour options are Blue, Colorful, Green, Red and White. No speed sensor is supported, so fan speed monitoring is not available.

Features and Construction

The fan is built around a stated oil seal bearing and a 120x120x25mm frame. These details make it straightforward to compare against the mounting space available in a PC case. The source data lists specific electrical and airflow figures, which helps buyers check compatibility with a 12V DC fan header and estimate whether the fan matches their ventilation needs.

Material and Build

The bearing type is an oil seal bearing, which is the only construction detail given for the fan mechanism. It is rated for 30,000 hours according to the source data. The fan weighs 75 grams. No further information about the housing material, blade material or frame construction is provided in the source text, so the description is limited to the stated bearing type, weight and dimensions.

Size and Practical Fit

The fan measures 120x120x25mm (W x H x D), a common size for PC case fan mounts. The 25mm depth is a relevant measurement when checking clearance near motherboard components, drive cages or cable routing. The 30cm line length gives some flexibility when connecting to a fan header, although the exact reach will depend on the internal layout of the case. No additional mounting accessories or screws are confirmed in the source data.

Uses and Placement

This fan is intended for computer case cooling and similar 12V DC fan applications where a 120mm fan mount is available. Its airflow and pressure figures are stated, so it can be assessed for general case ventilation rather than for a specific performance category. The blue light option and other colour choices may also be relevant for builders matching fan colour to a case theme.

Event or Professional Use

For professional or workshop environments where a standard 120mm 12V DC fan is needed, the stated figures provide a clear basis for checking suitability. The 4-pin connector, 30cm cable, 1100 RPM speed and 22.84 CFM airflow are all documented. The absence of a speed sensor should be noted where speed monitoring is required. No additional professional certifications or specialist ratings are stated in the source text.

Everyday Home Use

In a home desktop PC, this fan can be used as a case fan for general airflow. Its 22 dB-A noise level is a stated figure, and the 30,000-hour bearing life is given for the oil seal bearing. The 120x120x25mm size means it can be fitted where a standard 120mm mount is present. The source data does not confirm PWM control, RGB lighting or bundled mounting hardware, so these should not be assumed.

Benefits and Buying Value

The main buying considerations are the documented 120mm size, 12V DC operation, 4-pin connector, 1100 RPM speed and stated airflow and noise figures. These details allow a buyer to compare the fan against a specific build requirement. The colour options give some choice for visual matching, while the stated bearing life and low measured weight round out the available information.

Reuse and Low Maintenance

The oil seal bearing is rated for 30,000 hours according to the source text. Keeping the fan free from dust is a basic precaution that can help maintain airflow, but no specific cleaning products or procedures are stated. The fan uses a 4-pin connector and a 30cm cable, so reuse in another compatible 12V DC system depends on those connections being available. No further maintenance or service instructions are provided in the source data.

Why Choose This Product

This 120mm fan offers documented specifications rather than vague performance claims. It provides 22.84 CFM airflow, 1.78 mmH2O air pressure, 1100 RPM, 22 dB-A noise and a 30,000-hour oil seal bearing rating. It is available in Blue, Colorful, Green, Red and White, and it uses a 4-pin connector with a 30cm cable. Buyers who need a standard-size 12V DC case fan with these exact figures can use the listed data to check compatibility. No speed sensor is supported, and no additional features beyond those stated should be expected.
