We recently filmed a run on one of our CNC setups: a rotary fixture plate holding several metal fan housing components at once, a multi-head

A customer once sent us a video of a fan that “sounded fine on the bench” but hummed audibly once it was screwed into their

Same fan. Same 220V supply. Same everything, except the frequency of the power feeding it. And the fan still ends up spinning at two different

Every DC cooling fan comes down to a motor spinning an impeller on a bearing, and that bearing determines more about the fan’s real-world behavior

Two fans can share the same footprint, list similarly impressive airflow numbers on the spec sheet, and still behave in completely different ways once they’re

A customer came to us recently with a problem that doesn’t come up often, but when it does, it’s a real headache: their fan kept

Sometimes the biggest reliability problems come from the smallest details. A customer recently came to us with a 45 × 45 × 10 mm centrifugal

A few weeks ago one of our clients called us pretty concerned. They’d been testing a custom bracket axial fan we built for them, and

The Problem: Miniature Devices, Massive Heat Let’s face it. Designing for “micro” is a thermal nightmare. 🌡️ You’re building a smart wearable, a medical sensor,
