Slim 80mm case fan for tight spaces

The Athena Power FANC-TB815 is an 80mm slim fan designed for cases with limited clearance. Its 8015 form factor fits narrow chassis slots where standard thickness fans cannot. Builders working on compact or low-profile systems will find it a direct fit.

3-pin connector with 4-pin adaptor included

The fan ships with a 3-pin 3-wire power connector and a 3-to-4-pin adaptor for broader motherboard compatibility. Speed control depends on the header type used; 3-pin headers adjust voltage while 4-pin headers enable PWM. No other interface or control method is provided.

23.6 CFM airflow at 18 dBA noise

Twister bearing technology and turbine blades deliver 23.6 CFM of high-pressure airflow while operating at 18 dBA. This level suits targeted component cooling or exhaust in small enclosures. It will not move enough air for high-heat multi-GPU builds or full-tower radiators.

Questions about this item

Should I choose the 80mm slim version or a thicker 80mm fan?

The FANC-TB815 is a 15mm slim model (8015). Pick it when your case or cooler only clears a thin fan; a standard 25mm fan will not fit in that space.

What does 23.6 CFM actually deliver inside a case?

23.6 CFM moves enough air for low-heat components or tight side-panel vents, but it will not cool a high-TDP CPU or GPU on its own.

How does the 3-pin connector with 4-pin adaptor limit control?

The 3-pin wire allows voltage-based speed control only; the included 3-to-4-pin adaptor lets you plug into a 4-pin header but does not add PWM signalling.
