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

Fans

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

  • Key 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.

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.
