Who it fits

Key specs explained for you

75x75x30mm (2.95 x 2.95 x 1.18 inches)

This compact footprint fits small enclosures where standard 80mm or 120mm fans cannot. You should measure your available space carefully before purchasing. This size is distinct from typical CPU air coolers, which usually require larger mounting areas. It suits tight cases or specific electronics rather than standard desktop PC builds.

DC24V, 0.15A

The fan requires a 24-volt power supply, not the standard 12V found in most PC motherboards. You must verify your power source matches this requirement. Using the wrong voltage can damage the unit. This specification separates it from standard PC cooling components, making it suitable for specialized equipment like 3D printers.

Centrifugal blower

This design forces air through a narrow outlet, creating high static pressure. It moves air efficiently through dense heatsinks or restricted vents. Unlike axial fans that move large volumes of air, this unit pushes air against resistance. It is ideal for cooling specific components like GPUs or CPUs in confined spaces.

Dual ball bearing

This bearing type offers greater durability and longevity compared to sleeve bearing fans. It handles higher temperatures and continuous operation better. You can expect a longer service life, which reduces the need for frequent replacements. This makes it a reliable choice for equipment that runs for extended periods without shutdowns.

27cm cable length

The 10.6-inch wire provides moderate reach for internal connections. You may need extension cables if your power source is distant. This length is sufficient for most standard mounting positions but may require management in tight cases. Ensure the cable does not obstruct airflow or other components during installation.

Design and build details

The listing describes this unit as a centrifugal blower fan with a dual ball bearing construction. This mechanical choice suggests a focus on longevity rather than silent operation. The housing is made of plastic materials common for this class of component. The design prioritizes airflow direction over acoustic dampening. You should expect a functional, industrial appearance rather than a decorative finish. The build is utilitarian, intended for internal mounting within electronic devices.

Dimensions are listed as 2.95 inches by 2.95 inches with a height of 1.18 inches. The weight is 0.35 ounces. This light weight is typical for small blower fans. The compact size allows it to fit into tight spaces where standard square fans cannot. You must verify your enclosure dimensions carefully. The mounting hole diameter is 0.18 inches, with a center-to-center distance of 3.15 inches. These specific measurements are critical for compatibility with existing chassis or heatsink mounts.

A 10.6-inch cable length is included. This length provides some flexibility for routing wires to a power source. The listing notes the fan is suitable for notebook motherboards, GPUs, and 3D printers. The design is not optimized for CPU air cooling in standard desktop towers. Instead, it targets localized heat dissipation in confined areas. You should consider these physical constraints when deciding if this blower fits your specific hardware layout.

Setup and everyday use guide

Installation follows a straightforward three-step process outlined in the product features. You begin by verifying the dimensions match your available space. The listing specifies a 2.95-inch by 2.95-inch footprint with a 1.18-inch height. You must ensure the mounting hole diameter of 0.18 inches aligns with your chassis or device. The center-to-center distance between holes is 3.15 inches. Once confirmed, you remove the existing fan and secure this unit in its place. The included cable measures 10.6 inches in length, providing some flexibility for routing wires to your power source. This fan operates on 24V DC at 0.15A, so you need a compatible power supply. It is designed for use in notebook motherboards, PCs, GPUs, CPUs, video cards, 3D printers, and speakers. The dual ball bearing construction implies it can handle continuous operation without immediate wear. You should expect low noise levels during daily use, as stated in the features. This makes it suitable for environments where excessive sound is undesirable. The compact size allows it to fit into tight spaces where standard fans cannot go. You can use it as a direct replacement for older units or as an addition to your cooling setup. Ensure you select the correct size before installation to avoid fitment issues. The listing notes it is a good repair or replacement accessory, suggesting it integrates easily into existing systems.

Before You Buy This Fan

You are buying a specialized blower, not a standard CPU air cooler. This unit moves air in a focused stream rather than dispersing it broadly. You need to verify that your target component, such as a GPU or 3D printer hotend, fits within the 2.95 by 2.95 inch footprint. The 24V DC power requirement means you must have a compatible power source or controller. Standard 12V systems will not work. Check your mounting hole center distance, which is 80mm, to ensure it aligns with your chassis or bracket. The dual ball bearings suggest this fan can run for long periods without failure, but you should keep the intake clear of dust. This fan complements traditional air coolers by handling localized heat sources. It does not replace a large heatsink for a main processor. Use it where space is tight and directed airflow is critical. Ensure your cables, including the 27cm length, can reach your power connector without obstruction.

Check before you buy

• Verify your space fits the 2.95 by 2.95 inch size.
• Confirm your power supply provides 24V DC, not 12V.
• Check that the 80mm mounting hole center distance matches your mount.
• Ensure the 4.5mm mounting hole diameter fits your screws.
