Cooling fan knowledge from our engineering team — selection guides, technology comparisons and application notes.
Practical, engineering-first articles written by the people who build the fans.
A practical six-step method for selecting a DC axial cooling fan: heat load, enclosure space, airflow vs static pressure, voltage, bearing and noise.
Read Article →A side-by-side comparison of DC, AC and EC cooling fans: efficiency, speed control, wiring, cost and the applications where each technology wins.
Read Article →Why rated CFM is misleading, how to read a P-Q curve, and how system resistance decides whether an axial fan or a blower is the right choice.
Read Article →Sleeve, hydraulic and dual ball bearings explained: how each behaves at temperature, in vertical mounting and over a five-year product life.
Read Article →What burn-in and aging tests actually catch, how a proper aging room is run, and the questions buyers should ask before approving a fan supplier.
Read Article →How IP ratings are defined, what IP68 really requires from a fan, and the design details that decide whether an outdoor cooling system survives rain, dust and cleaning.
Read Article →Two ways to slow a fan down — and why one of them silently shortens bearing life. Wiring, control range, noise and failure modes compared.
Read Article →Where fan noise actually comes from, how to measure it honestly, and eight fixes that work — from impeller balancing to grill geometry.
Read Article →Why a blower can outperform a bigger axial fan in tight, restrictive enclosures — and when it is the wrong tool entirely.
Read Article →Thermal and environmental requirements for cooling fans in AC/DC chargers, on-board chargers and battery packs — including IP rating, wide temperature and lifetime targets.
