Compact 80 mm case fan for tight builds
The Vszerda EFC-08E12D-EF05 is an 80 mm square fan with a 25 mm thickness that fits small-form-factor chassis and tight clearance zones. It runs on DC 12 V and draws 0.40 A through a three-wire interface, so speed reporting is available without PWM control. Dual ball bearings support continuous operation in always-on systems. This new unit suits integrators who need a direct replacement for an 80 mm mount.
Suits small chassis and legacy mounts.
Builders working with mini-ITX cases, 1U servers or older enclosures that only accept 80 mm fans will find the mounting holes line up exactly. The three-wire connector reports RPM but does not accept a PWM signal, so boards that require four-pin control cannot regulate speed automatically. Buyers who need higher static pressure for dense radiators or who want motherboard-controlled fan curves should look at something else.
Three-wire interface decides motherboard control
The connector carries power, ground and a tachometer lead only; there is no fourth wire for PWM duty-cycle input. If your header or controller expects a four-pin fan to vary speed automatically, this fan will run at full voltage constantly. Check the header specification before ordering.

Questions about this item
How much heat does the 12 V 0.40 A fan add when running continuously?
At 12 V and 0.40 A the fan draws about 5 W, so its own heat contribution stays small during all-day operation.
What motherboard header do I need for the three-wire interface?
A standard 3-pin 12 V fan header is required; the fan will run at full speed unless the board supports voltage control.
Will the 80 mm 25 mm frame fit in the same mount as my older 80 mm fan?
Yes, the 80 x 80 x 25 mm dimensions match the common 80 mm mounting pattern used by older fans.
