Compact 40 mm 5 V Case Fan

The YM0504PFS3 is a 40 by 40 by 10 mm case fan that runs on 5 V and draws 0.19 A through a three-wire connection. Its small frame fits tight chassis spaces where larger coolers cannot be mounted. The unit is supplied new and intended for targeted airflow in computer cases or embedded enclosures.

For Space-Constrained Cooling Slots

This fan suits builders who need a low-voltage 40 mm cooler for compact boards, small-form-factor cases or replacement of an identical 3-wire unit. Buyers who require higher airflow, PWM speed control or a larger mounting footprint should look at other options.

Questions about this item

How much current will the 5 V fan draw once it is installed?

The fan is rated at 0.19 A on a 5 V supply, so that is the current it will pull when running in your system.

What does the three-wire connection actually provide for speed control?

The three wires carry power, ground and a tachometer signal; the motherboard can monitor RPM but cannot vary voltage through PWM on this header.
