Small black square 70mm cooling fan with four-pin connector and 19cm cable

Fans DA07015T12U 70mm 12V 0.7A 4-pin fan

SKU CH-R2KX-2YEF4

A 70 mm 12 V 4-pin cooling fan with adjustable 1950-4400 RPM speed, single ball bearing and 40000-hour life

  • FeaturesFan
  • Intelligent speed control adapts 1950–4400 RPM to workload
  • Single-ball bearing rated for 40000 hours of operation
  • Quiet 19–30 dBA noise range suits noise-sensitive builds
  • Standard 4-pin motherboard header with speed monitoring support
  • 19 cm cable reaches CPU, chassis or PSU fan mounts

Purpose-built cooling fan

This 70 mm square fan fits CPU heatsinks, chassis vents, power-supply housings and auxiliary water-cooling loops. It targets builders who need a direct 478-replacement blade assembly with a 12 V 0.7 A draw. The unit is not for buyers who want a larger frame size or a different voltage rail.

Build integration

A 19 cm lead reaches standard motherboard 4-pin headers for PWM speed monitoring and control. The 70 mm × 70 mm × 15 mm footprint slides into tight server or console enclosures without requiring adapter brackets. It frees the builder from sourcing proprietary OEM spares for legacy 478 platforms.

Capacity and headroom

Single-ball bearing life is rated at 40 000 hours across a 1 950 to 4 400 ± 10 % RPM range. Acoustic output spans 19 to 30 dBA ± 3 dBA, so noise rises noticeably at the top of the curve. The fan runs out of headroom when thermal loads demand sustained airflow beyond its maximum rated speed.

Highlights

  • Intelligent speed control adapts 1950–4400 RPM to workload
  • Single-ball bearing rated for 40000 hours of operation
  • Quiet 19–30 dBA noise range suits noise-sensitive builds
  • Standard 4-pin motherboard header with speed monitoring support
  • 19 cm cable reaches CPU, chassis or PSU fan mounts

Questions about this item

How long can the fan run continuously at its rated 12 V and 0.7 A before thermal throttling might limit speed?

The fan is rated for 40,000 hours of bearing life at its specified voltage and current, with speed monitored via the 4-pin interface to maintain 1950–4400 RPM ±10% under sustained load.

What noise level and heat output should I expect when the fan runs all day at maximum 4400 RPM?

At top speed the noise reference reaches 30 dBA ±3 dBA; the 0.7 A draw at 12 V produces modest heat, and the single-ball bearing is rated for 40,000 hours of continuous operation.

Which existing connector and mounting spacing must my motherboard or chassis provide for this 70 mm × 70 mm × 15 mm fan?

It requires a standard 4-pin motherboard header and 70 mm square mounting holes; the 19 cm lead reaches most CPU cooler, chassis, PSU or water-cooling positions.
