80 mm 4-line case fan

The Fans 3110el-04w-m66 is an 80 mm case fan built for compact chassis that need directed airflow. Its four-wire interface allows speed control through the motherboard so the fan runs only as fast as required.

Thermals noise and power

At 12 V and 0.36 A the fan draws modest power while moving air through tight spaces. The 4-line design keeps acoustic output low during typical operation because the speed curve can stay near the minimum duty cycle.

Questions about this item

How do I connect the four-wire cable of the 3110el-04w-m66 fan to my motherboard?

Align the four-pin connector with the motherboard's 12 V PWM header; the keyed plug prevents reverse insertion, which is the step most often missed.

When should I plan to replace the bearings in this 8025 silent fan?

The sleeve-bearing design typically runs quietly for several years; replace the unit once you hear a steady rattle or notice a drop in airflow at 0.36 A.
