Dell Compatibility

This 120 x 38 mm case fan is built for Dell Dimension 3100 5100 5150 E310 E510 E520 E521 9100 9150 9200 XPS 400 410 Precision 380 390 690 PowerEdge SC440 SC430 830 Optiplex GX280-05 210L GX320 GX520 MT GX620 MT GX740 745 745c systems. It replaces Dell part numbers D8794 Y4574 H7058 D6168 CH9743 G9096 and uses a four-wire lead that terminates in a 5-pin Dell connector with white TAC sensor red power black ground and blue PWM control wires.

Who It Suits

System integrators and owners of the listed Dell chassis who need a direct-replacement 12 V 1.60 A 19.20 W PWM fan with ball bearings will find the correct fit and connector here. Builders working on non-Dell cases or anyone who prefers a standard 4-pin PWM header without the proprietary Dell plug should look elsewhere.

Deciding Specification

The fan delivers 3900 RPM 148.34 CFM airflow and 15.29 mm H²O static pressure at 51 dBA noise so the single figure that decides fit is the 5-pin Dell connector paired with the 120 x 38 mm frame.

Questions about this item

How long do the ball bearings typically last before needing replacement?

Ball bearings in this fan generally run for tens of thousands of hours at 3900 RPM before wear requires replacement.

Will the 19.20 W power draw or 51 dBA noise become the limiting factor during continuous operation?

The 51 dBA noise level at full speed is the practical limit most users notice before the 19.20 W power draw stresses a standard 4-pin header.

How much heat does the fan add to the case when running at 3900 RPM all day?

The motor draws 19.20 W at 12 V, converting nearly all of it into heat inside the chassis during sustained operation.
