Black square 70mm PWM case fan with four-wire connector

SXDOOL

SXDOOL DV07020B12U 70mm 4-wire PWM case fan

SKU CH-6F1T-RMFED

A 70 mm case fan with 4-wire PWM speed control, double-ball bearings, 650–4400 RPM range and 19–30 dBA noise rating

  • 4-wire PWM enables intelligent temperature-controlled speed
  • Double ball bearing rated for 40000 hours service life
  • 650 to 4400 RPM range covers silent to high airflow
  • 19 to 30 dBA noise level stays quiet at low speeds
  • Compact 70mm by 70mm by 20mm fits tight spaces

Compact 70 mm PWM fan for tight builds

The SXDOOL DV07020B12U is a 70 mm square, 20 mm thick case fan built for small-form-factor chassis or CPU coolers that demand a slim profile. It runs on 12 V DC and draws 0.7 A, making it compatible with standard motherboard fan headers. The four-wire PWM interface allows the board to vary speed automatically between 650 and 4400 RPM based on temperature.

Double-ball bearing and wide speed range

A double-ball bearing supports a rated service life of 40000 hours at continuous operation. The broad 650 to 4400 RPM span lets the fan stay near-silent at idle — referenced at 19 dBA — while delivering strong airflow when the system loads up, peaking at 30 dBA. Intelligent temperature control on the PWM header handles the curve without extra software.

Four-pin connector with speed monitoring

The bundled 4-pin connector plugs directly into a motherboard PWM header and reports real-time RPM to the BIOS or monitoring utilities. No separate controller, adapter or RGB cable is included, keeping the install clean for builds that only need reliable, variable-speed cooling.

Questions about this item

At 4400 RPM what is the highest noise level this fan can reach?

The noise reference tops out at 30 DBA ± 3 DBA when the fan runs at its maximum 4400 RPM speed.

How much current does the fan draw continuously at 12 V?

It draws a rated 0.7 A at DC 12 V, so a standard 4-pin PWM header that supplies up to 1 A is sufficient.

Which motherboard header is required for PWM control and speed monitoring?

A standard 4-pin PWM header provides both the control signal and the tachometer feedback this fan uses.
