Square black 70mm frame 15mm thick four-pin PWM fan with 20cm cable

SXDOOL

SXDOOL D07R-12T3U 70x70x15mm 12V 0.29A 4-pin PWM hydraulic bearing case fan

SKU CH-ESDJ-985CJ MPN D07R-12T3U

A 70 mm hydraulic-bearing fan with 4-pin PWM control spins at 1000-4000 rpm for case or GPU cooling

  • PWM control adjusts fan speed from 1000 to 4000 RPM
  • Hydraulic bearing reduces friction for quieter operation
  • 12 V 0.29 A draws only 3.5 W of power
  • 70 mm square by 15 mm thick fits tight chassis spaces
  • 20 cm 4-pin cable reaches most motherboard headers

Compact 70 mm PWM case fan

The SXDOOL D07R-12T3U is a 70 mm by 15 mm case fan that runs on 12 V and draws 0.29 A. Its hydraulic bearing and 4-pin PWM interface allow speed control between 1000 and 4000 RPM with a 10 percent tolerance. The unit ships with a 20 cm lead for motherboard connection.

Suits tight 70 mm mounts; not for larger frames

This fan fits chassis or heatsink slots that accept a 70 mm square footprint and a 15 mm thickness. It is not for builds that require a larger frame size, higher airflow than 3.5 W can deliver, or a different bearing type. The fixed 20 cm cable may also limit routing in full-tower cases.

4-pin PWM hydraulic bearing decides fit

The 4-pin PWM header and hydraulic bearing together determine whether this unit matches the motherboard header and noise profile you need. If your board only offers 3-pin voltage control or you prefer a different bearing technology, this model will not meet those requirements.

Questions about this item

How is the 70mm 4-pin PWM fan installed, and what step do people get wrong?

Mount the 70x70x15mm frame with four screws, plug the 4-pin connector into the motherboard 4PIN header, and route the 20CM wire so it does not snag on nearby components; the common mistake is leaving the PWM wire unplugged, which locks the fan at full 4000 RPM instead of letting it scale from 1000 RPM.

What maintenance or replacement will the hydraulic bearing need later?

The hydraulic bearing is sealed and not user-serviceable; when noise or vibration appears after extended running, replace the entire 12V 0.29A unit rather than attempting to lubricate it.

What limit shows up first under sustained 3.5W load at 4000 RPM?

Continuous operation at the top 4000 RPM speed increases bearing wear and audible noise before the 12V 0.29A motor hits its thermal ceiling, so expect the acoustic limit to arrive first.
