120 mm Blue LED Case Fan

The FSP CF12S11 is a single 120 mm case fan designed for standard computer chassis. It suits builders who want a quiet, LED-lit intake or exhaust fan for everyday cooling tasks. The blue LED adds a subtle visual accent without requiring separate lighting controllers. This fan is not for users needing PWM speed control or high-static-pressure airflow for dense radiators.

3-Pin Connector and Sleeve Bearing Limits

The fan connects via a 3-pin power header, so speed varies only with voltage changes from the motherboard. Sleeve bearings run quietly at the rated 1000 RPM but can wear faster than ball bearings in horizontal mounting orientations. Maximum airflow reaches 39.4 CFM at a noise level of 20 dBA. There is no PWM signal wire for precise, automatic fan curves.

Simple Screw Mounting with Cable Routing Care

Four corner screw holes match standard 120 mm mounting points on any compatible case. The 3-pin cable is fixed, so route it before securing the fan to avoid tension on the header. Ensure the arrow-marked airflow direction points toward the interior for intake or toward the rear for exhaust. Over-tightening screws can crack the plastic frame.

Questions about this item

Should I pick the 3-pin version or look for a 4-pin alternative?

This model uses a 3-pin power connector, so speed is controlled by voltage. It works on any 3-pin or 4-pin motherboard header, but PWM control is not available.

What does the 39.4 CFM rating mean for my build?

At 1000 RPM the fan moves 39.4 CFM of air, which is suited to standard chassis airflow rather than high-restriction radiators or dense heatsinks.

How does the 3-pin connector limit speed control?

The 3-pin header varies voltage to change RPM; the fan will spin at roughly 1000 RPM at 12 V and slow down at lower voltages, but it cannot accept a PWM signal.
