Fan Optimisation: the Balance Between Noise, Size, and Airflow

When we first started designing Fantail, we found every fan has to balance three key things: noise, size, and airflow.

It sounds simple, but it’s a tricky equation. You can’t have all three at their maximum.

Why You Can’t Max Out Everything

When it comes to fans, there’s always been a trade off.
If you want something quiet and compact, you usually have to sacrifice airflow.
If you want something small and powerful, it often ends up noisy because the fan has to spin faster.
And if you want the strongest airflow with low noise, you typically end up with a big, bulky fan that dominates the room.

Fan performance isn’t just about motor speed, bearing type, blade geometry, and especially the housing design all play a major role in how loud or efficient a fan can be. We spent over a year refining the aerodynamic design of Fantail’s fan housing, producing countless 3D printed prototypes and measuring airflow and noise after every iteration. Every small change made a measurable difference.

Our goal was clear from the start: create a fan system that’s compact, quiet, and still delivers strong, effective airflow. After hundreds of tests and refinements, we achieved exactly that.

How We Found the Sweet Spot

Most fans on the market lean too far in one direction. You get the powerful but noisy ones, or the small quiet ones that barely move air.

With Fantail, we didn’t want you to have to pick between them. So we spent months testing, refining, and tuning the design until we found what felt right.

The result is a fan that delivers:

• Airflow strong enough to keep you cool through the night

• A quiet sound that’s consistent, more like soft white noise than a whine

• A compact size that actually fits comfortably at the end of your bed

It wasn’t easy, but that’s kind of the point. We wanted to remove the need to compromise.

Why It Matters

Sleep quality is shaped by your environment. Too much heat and you toss and turn. Too much noise and you can't get to sleep.

Fantail was designed to sit right in the middle. It keeps you cool, with a quiet sound that’s easy to sleep with, and fits nicely in your bedroom.

What’s Next

We’re excited to share that fantail is available for preorder: click here to preorder now. Fantail has been through countless design iterations to get this balance right, and we think it performs better than anything else out there.
