Compact 80mm 4-wire CPU fan

This OEM Industries cooler is a square 80mm fan built for CPU air-cooling duties. It runs on 12V at 0.15A and uses a ball bearing for durable operation. The 4-wire PWM connection allows the motherboard to control speed precisely. No LED lighting is included.

Replaces noisy or failed 8025 stock coolers

The unit fits the standard 80*25mm mounting pattern found on many older or low-profile sockets. It is a direct drop-in when the original fan has worn bearings or insufficient airflow. The upgrade is worth it when system temperatures rise under load or acoustic noise becomes distracting.

Verify 4-pin header and mounting holes before

Confirm the motherboard provides a 4-pin CPU fan header for full PWM control. Check that the cooler’s screw holes align with the socket retention frame. Ensure the chassis has enough clearance for the 25mm thickness. The fan is sold alone without heatsink or brackets.

Questions about this item

Does the 80mm square frame fit standard 80mm fan mounts?

The fan measures 80mm by 80mm with a 25mm thickness, matching the common 80mm square mounting pattern used on many heatsinks and cases.

How do I connect the 4-wire PWM lead to the motherboard?

Plug the 4-wire connector into a 4-pin CPU fan header; the extra wire carries the PWM signal so the board can control speed automatically.

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

Ball bearings typically last several years of continuous use; replace the fan if noise increases or RPM drops below the rated 0.15A current draw at 12V.
