70mm 12V CPU fan for compact builds

The OEM Industries DA7020B12U is a 70mm ball-bearing fan designed for CPU cooling in space-constrained systems. It runs on 12V DC and draws 0.70A, making it suitable for low-profile towers or small-form-factor cases. The black frame and blade design fit standard 7020 mounting patterns. Buyers needing larger airflow or radiator-mounted cooling should look elsewhere.

Simple three-pin installation

The fan connects via a standard 3-pin power connector that plugs directly into most motherboard CPU fan headers. Two-ball bearing construction reduces friction and extends operating life compared to sleeve alternatives. Ensure the header supplies a full 12V signal; some low-power headers may not spin the fan up to speed. No LED lighting or PWM control is included, so speed is voltage-regulated only.

Verify 70mm clearance

Measure the available height above your CPU socket to confirm a 70mm fan fits without contacting side panels or memory modules. Check that the motherboard provides a 3-pin CPU fan header at 12V; 4-pin PWM headers will run the fan at fixed voltage but without speed reporting. Confirm the 7020 mounting hole spacing matches your heatsink or bracket. Systems requiring PWM control or larger fan diameters cannot use this unit.

Questions about this item

How can I confirm the 70mm fan is spinning correctly after installation?

Connect the 3-pin header to the motherboard and verify rotation in BIOS or monitoring software; the ball bearing design should run smoothly at 12V.

What comes in the box and do I need any extra cables or mounts?

The package contains the 7020 fan unit only; mounting screws and any additional wiring must be sourced separately.

Which version of the DA7020B12U should I choose for a standard CPU header?

This model is a 12V, 0.70A ball-bearing fan with a 3-pin connector, matching typical CPU fan headers.
