  • 2 cm hole spacing matches common chassis patterns

Purpose and audience

The SXDOOL KDE1209PTVX is a 90mm maglev case fan built for system builders who need a 12V PWM cooler with a standard four-pin motherboard header. Its 92mm square frame fits common 90mm mounting points spaced 7.2cm apart. The fan targets compact chassis or server upgrades where a thin 25mm profile and magnetic-levitation bearing are specified.

Decisive specification

Speed ranges from 850 to 4200 rpm ± 5% while drawing 4.4W at 0.40A, so the single figure that determines fit is the PWM-controlled speed curve. Builders who require a fixed low-noise ceiling or a higher maximum airflow than this range provides should select a different model. The four-wire connector enables automatic motherboard control without external controllers.

Sustained-load behaviour

Magnetic-levitation bearings eliminate physical contact between shaft and sleeve, reducing friction-induced wear during continuous operation. At full 4200 rpm the motor maintains the rated 4.4W draw without the bearing degradation seen in sleeve or ball designs under prolonged heat. The 25mm thickness keeps airflow path short, helping the fan sustain its speed envelope in restricted ducting.

Questions about this item

What does the 4.4 W draw mean for my motherboard header?

At 12 V the fan pulls roughly 0.40 A, well within the typical 1 A limit of a standard 4-pin CPU or chassis header.

How does the 4-pin PWM connector limit speed control?

The 4-pin plug lets the motherboard vary voltage on the PWM line, so the fan can run anywhere between 850 and 4200 rpm.

Will the 7.2 cm hole spacing fit my 90 mm mount?

Yes — the 92 mm square frame uses 7.2 cm centre-to-centre holes, the standard pattern for 90 mm fan mounts.
