SXDOOL

SXDOOL QFR1212GHE 120×120×38 mm 12 V 2.7 A 4-pin PWM case fan

SKU CH-5PCG-ARNFV MPN QFR1212GHE

A 120×120×38 mm 12 V PWM fan moves 210.38 CFM at 6000 RPM with 21.60 mmH₂O static pressure and 64 dB-A noise using a double ball bearing rated for 80,000 hours at 25 °C

  • TypeCase Fan
  • Power Connector4 Pin
  • High airflow of 210.38 CFM for rapid heat removal
  • Strong static pressure of 21.60 mmH2O pushes air through dense heatsinks
  • Double ball bearing rated for 80,000 hours at 25 °C
  • Flame-retardant PBT frame with 30 % glass fibre for durability
  • 4-pin PWM control enables precise speed adjustment from 6000 RPM

Industrial-grade 120 mm PWM fan

The SXDOOL QFR1212GHE is a 120×120×38 mm DC 12 V case fan rated at 2.7 A. It targets workstation and server CPU cooling where sustained high static pressure is required. The 4-pin PWM connector allows automatic speed control by the motherboard. Its double ball bearing and PBT frame with glass fibre are built for continuous operation.

Double ball bearing and flame-retardant frame

The high-precision double ball bearing reduces friction compared with sleeve designs, extending the rated life to 80,000 hours at 25 °C ambient. The frame and impeller use PBT plus 30 % glass fibre rated VO for flame retardance. These materials keep structural integrity across the -10 °C to +70 °C operating range. No extra accessories or software are included in the package.

4-pin PWM control and 12 V power limits

Speed is governed by the 4-wire PWM signal, letting the system vary RPM up to the 6000 maximum. The fan draws up to 2.70 A at 12 V, so the motherboard header or fan controller must supply that current continuously. Insulation resistance exceeds 500 megohms and the unit withstands 500 V AC for one minute. Counter-clockwise rotation when viewed from the label side fixes the airflow direction.

Questions about this item

What is the expected lifespan of the double ball bearing at 25 °C ambient?

The manufacturer rates the working life at 80,000 hours at 25 °C ambient temperature.

Which limit appears first during sustained operation — airflow, static pressure or noise?

At 6,000 RPM the fan delivers 210.38 CFM airflow and 21.60 mmH₂O static pressure at 64 dB-A noise.

How much heat and power does the 12 V 2.7 A motor add to a chassis running all day?

The fan draws up to 2.7 A at 12 V with a rated power tolerance of ±15 % and operates up to 70 °C.
