Compact 70 mm blower fan

The SunnyStar TYF350LJ01 is a 70 mm square blower fan designed for tight enclosures such as DLP projectors and small-form-factor cases. It runs on 12 V and draws 0.35 A for 4.2 W of power through a 3-pin connector. Ball bearings provide consistent rotation in the black frame.

Suited for projector and slim-case cooling

This unit fits builders replacing a 7025-size blower in projector housings or compact chassis where a radial airflow pattern is required. It is not for systems that need a 4-pin PWM header or a larger mounting footprint. Buyers wanting temperature-controlled speed curves should look elsewhere.

3-pin fixed-voltage connector

The 3-pin power connector delivers constant 12 V supply without PWM signalling, so fan speed stays fixed unless the motherboard or controller supports voltage regulation. Verify that the target device accepts a 3-wire 70 mm blower with 7025 mounting centres before ordering.

Questions about this item

Will the 70mm blower fit a 70mm x 25mm mounting cut-out?

The fan measures 70mm square by 25mm thick, so it matches a standard 70mm x 25mm mounting pattern.

Which way does the 3-pin connector key align when plugging it into a 12V header?

The three-pin plug has a key tab that lines up with the header notch; press straight down until the latch clicks to avoid bent pins.

How often should the ball-bearing blower be cleaned to maintain 4.2W airflow?

Use compressed air to clear dust from the blower wheel and vents every six to twelve months; the sealed ball bearing needs no lubrication.
