Zyvpee 40×20 mm 5 V case fan

The Zyvpee EFB0405LD is a compact 40 by 20 millimetre case fan built for tight spaces inside routers, switches or small-form-factor PCs. It runs on a 5 V supply and draws only 0.16 A through a simple two-wire lead. The black, non-LED frame keeps the look understated while the ball bearing aims for a long service life.

5 V two-wire power connector

The single specification that decides compatibility is the 5 V two-wire power connector; the fan will only work with headers or adapters that provide exactly 5 volts and accept a two-pin plug. No PWM control or tachometer signal is present, so speed is fixed once power is applied. Verify that your device offers a matching 5 V header before purchase.

Ball bearing thermals and acoustics

In normal use the ball bearing runs quietly while moving enough air for router or switch cooling duties. The low 0.16 A current draw means minimal impact on the 5 V rail and negligible extra heat inside the chassis. Expect steady, maintenance-free airflow without the rattle that can appear in sleeve-bearing fans over time.

Questions about this item

How much current does the 5 V fan draw when running?

The fan is rated at 0.16 A, so it pulls roughly 0.16 amps from a 5 V header or supply.

What connector does the fan use and how does it limit control?

It has a two-wire lead that delivers fixed 5 V power with no PWM or tachometer signal.

Will the 40 mm by 20 mm frame fit my router or switch chassis?

The housing measures 40 mm square by 20 mm thick; check your device's fan cut-out and mounting holes against those dimensions.
