80 mm DC axial fan for Cisco 3845

This 80 mm DC axial fan fits the Cisco 3845 platform and similar 8025 devices. It draws 0.38 A from a 12 V supply and connects through a three-pin header. The black frame measures 80 by 80 by 25 mm and uses a ball bearing for steady rotation.

Replaces noisy or failed 80 mm three-pin fans

When an existing 80 mm fan exceeds 35 dBA or stops spinning, this unit restores airflow at 3500 to 3999 RPM. The upgrade is worth it when the original bearing has worn out or when a non-LED, ball-bearing design is required for continuous operation.

Handles standard chassis cooling loads

At 30 to 35 dBA the fan delivers enough static pressure for typical rack-mount chassis without adding audible distraction. It runs out of headroom in high-density enclosures that demand higher static pressure or PWM speed control beyond the three-pin interface.

Questions sur cet article

Does the 80×25 mm frame match the mounting holes on a Cisco 3845 chassis?

The fan is listed as compatible with Cisco 3845 and 8025 devices, so the 80×25 mm frame aligns with those mounting patterns.

How do I connect the 3-pin power lead to the motherboard or fan header?

Align the three-pin connector with the 12 V fan header, match the keyed tab, and press straight in; forcing it sideways can bend the pins.

When should I plan to replace the ball-bearing fan?

Ball bearings typically last many years at 3500–3999 RPM; replace the fan if noise rises above the 30–35 dBA range or airflow drops noticeably.
