80 mm 24 V dual-ball case fan

The SXDOOL 3115RL-05W-B66 is an 80 mm square frame fan built for 24 VDC equipment cooling. It draws 0.50 A through a 4-wire connection and uses a high-precision dual-ball bearing for continuous duty. The black non-LED housing measures 38 mm thick and fits standard 80 mm mounting holes.

Industrial and server chassis cooling

This fan suits maintainers who need a genuine NMB 3115RL-05W-B66 replacement in 24 V rack gear or telecom enclosures. It does not suit builders who want integrated lighting or who need a different voltage supply.

24 VDC 0.50 A power rating

The 24 VDC 0.50 A rating is the single specification that decides fitment; the header must supply exactly that voltage and current capacity. The 4-wire lead provides tachometer feedback without assuming a particular control scheme.

Questions about this item

Will this 80mm 24V 4-wire fan connect directly to my existing 24V 4-pin header?

Yes, it uses a standard 4-pin connector designed for 24VDC systems matching the 0.50A current draw.

How can I verify the double ball bearing is running correctly after installation?

Listen for smooth, consistent rotation without grinding; the high-precision bearing should operate quietly at the rated voltage.

Does the box include mounting screws or a PWM cable adapter for the 3115RL-05W-B66?

The package contains the fan unit only; mounting hardware and any adapter cables must be sourced separately.
