Ruth's sister 70mm 12V .70A 4-pin PWM case fan

SKU CH-4MZG-M30DT

A 70 mm 12 V PWM case fan with 0.70 A draw and 4-pin control for targeted airflow

  • 12V 0.70A PWM delivers speed control for quiet cooling
  • 70 mm frame fits tight chassis slots without blocking components
  • 20 mm depth clears low-profile coolers and narrow cases
  • 4-pin connector enables motherboard fan-curve tuning

70 mm 12 V PWM case fan

This 70 mm case fan runs on 12 V and draws 0.70 A through a standard 4-pin PWM connector. It fits the 70x70x20 mm footprint referenced as 7020 and suits builds that need compact air-volume cooling for CPU or chassis zones. The fan is new and ready for direct motherboard control.

Check your motherboard header and mounting points

Verify that your board has a free 4-pin PWM header and that the 70 mm screw pattern matches your case or heatsink. Confirm the 12 V supply can provide the rated current alongside other components. Ensure physical clearance for the 20 mm thickness in the intended location.

Questions about this item

Does the 70 mm 12 V 4-pin PWM fan ship with mounting screws or do I need to buy them separately?

The fan is supplied as a standalone unit; standard 70 mm mounting screws are not included and must be sourced separately.

Should I choose the 0.70 A 12 V 4-pin PWM version or a lower-current model for my 7020 chassis?

The 0.70 A 12 V 4-pin PWM model delivers the airflow spec for the 7020 form factor; a lower-current variant would move less air and may not meet cooling needs.
