SXDOOL 80mm PWM case fan

The SXDOOL QUR0812SH is an 80mm case fan designed for system builders who need active cooling in compact chassis or legacy motherboards that retain 80mm mounts. It draws .5 A at 12 V and uses a four-pin PWM connector so the motherboard can regulate speed automatically.

Four-pin PWM speed control limits

PWM control adjusts the fan between idle and the rated 5000 RPM, but the motherboard header must supply a clean PWM signal and sufficient current; boards that only offer voltage control on four pins will not modulate speed correctly. The .50 A draw also means headers limited to lower current may throttle or shut down the fan under load.

Straightforward 80mm installation

The fan fits standard 80 * 80 * 25 mm mounting holes and secures with four screws; no special brackets are required. Builders sometimes overtighten screws and distort the plastic frame, which can unbalance the hydraulic bearing and increase noise. Verify header orientation before powering on to avoid reversed polarity.

Questions about this item

Is the 80 mm frame with 25 mm depth the right fit for my case?

The fan measures 80 × 80 × 25 mm, so it fits standard 80 mm mounting holes with 25 mm clearance.

What airflow and noise should I expect from the 5000 RPM rating?

At 5000 RPM the hydraulic magnetic bearing moves a high volume of air; actual CFM and dBA depend on case restriction and fan curve.

Does the 4-pin PWM connector let the motherboard control speed automatically?

Yes, the 4-pin connector supports PWM intelligent temperature control so the board can vary speed from minimum to 5000 RPM.
