Compact blower fans promise targeted cooling for cramped electronics and 3D-printing parts, while remaining simple to fit and maintain. Quiet operation and a two-pack design give makers reassurance when swapping or upgrading components. Is the GDSTIME 40mm Blower Fan pair the right choice for reliable, small-form cooling needs?
⚡ At a Glance
- • Airflow: 3.62 CFM at 9,500 RPM, designed for rapid cooling in tight spaces
- • Best for: Part cooling in 3D printers, compact electronics and DIY cooling projects
- • Not ideal for: Large enclosures or applications that demand very high total airflow
Compact 40 x 40 x 10 mm blower fans run on DC 24V at 9,500 RPM and produce 3.62 CFM with around 35 dBA noise. Hydraulic bearings support continuous operation to roughly 35,000 hours and units include XH2.54 2-pin connectors plus mounting screws.
Fast, focused cooling - with a 9,500 RPM motor
High rotational speed generates the 3.62 CFM airflow figure, moving air quickly across small hotspots. Noise measures about 35 dBA at typical operating points, balancing performance and disturbance.
Rapid temperature reduction for small components, ideal for brief, intense cooling cycles on print layers or busy electronics boards.
Long run reliability - with hydraulic bearings
Hydraulic bearings reduce friction and heat, supporting continuous operation and lowering mechanical wear. Manufacturer guidance gives an approximate life expectancy of 35,000 hours under normal conditions.
Dependable duty for always-on installations, reducing the frequency of replacements in hobby or light industrial setups.
Simple DIY integration - with XH2.54 2-pin connector and compact size
Standard 40 x 40 x 10 mm dimensions match common mounting holes, while the XH2.54 2-pin plug allows direct connection to many hobby control boards at DC 24V. Two fans and mounting screws come in the package for immediate installation.
Straightforward fit-and-forget replacement or upgrade, making maintenance and spares management easier for makers and technicians.
