- Moves 54.57 CFM for strong chassis airflow
- 4600 RPM speed delivers high static pressure
- 2 dBA noise level keeps operation quiet
- 50000 hour rated life ensures long reliability
- 12 V 0.5 A draw fits standard fan headers
What this fan is and who it fits
The Delta QUR0812SH is an 80x80x25mm DC 12V case fan drawing 0.5A with a measured current of 0.36A. It spins at 4600 RPM and delivers 54.57 CFM of airflow at 0.33 in H₂O static pressure. The 4-wire connector supports PWM control for speed regulation. It suits builders needing a compact 80mm frame for tight chassis layouts or targeted component cooling.
What the four-wire lead and life rating change
The 4-line cable enables motherboard PWM control so the fan speed adjusts automatically with thermal load rather than running at a fixed voltage. A rated life of 50000 hours means the bearing is designed for continuous operation over several years without replacement. The 120mm total wire length reaches most 80mm mounting points without extensions.
Limits of the 80mm 12V PWM standard
At 41.2 dBA the acoustic output is noticeable in quiet rooms when the fan runs near 4600 RPM. The 8.40 mm H₂O maximum static pressure restricts use to open heatsinks or short airflow paths; dense radiators or long dust filters will reduce delivered airflow significantly. The 6.0W power draw is modest but requires a 12V header capable of at least 0.5A per fan.

Questions about this item
When will the fan need replacement given its 50000 hrs rated life?
The Delta QUR0812SH is rated for 50000 hours of operation, so replacement would typically be required after that many running hours under normal conditions.
What limit appears first during continuous 4600 RPM operation?
At full 4600 RPM speed the 41.2 d-BA noise level and 6.0 W power draw are the immediate limits you will notice during sustained use.
How much heat and power does it produce running all day at 12V?
Running continuously at 12 V it draws 0.5 A for 6.0 W of power, and the airflow of 54.57 CFM at 8.40 mm H2O pressure moves heat through the case.
