Compact 40 mm 12 V case fan

The Zyvpee gm1204pkb1-8a is a 40 mm square case fan designed for tight spaces such as 1U or 2U server chassis. It runs on a 12 V supply and draws 2.6 W, making it suitable for builds where a small footprint and low power draw are priorities.

Double ball bearing and three-wire connector

The fan uses a double ball bearing for durable rotation and a three-wire power connector that provides speed monitoring. Its 40 mm by 28 mm frame fits standard narrow mounting holes, and the non-LED black finish keeps the appearance neutral inside any enclosure.

High speed airflow at 9000 rpm

At 9000 rpm the fan moves 14.5 CFM of air through restrictive layouts, operating within a 4 V to 13 V range. The double ball bearing helps sustain this speed with consistent noise characteristics, while the modest 2.6 W power draw limits thermal load on the system.

Spurningar um þessa vöru

What does the 3-wire power connector limit for speed control on this 12V 40mm fan?

The three-wire connector supplies power and a tachometer signal but lacks PWM, so speed can only be adjusted by varying the DC voltage fed to the fan.

Will the 40mm by 28mm frame with double ball bearing fit a standard 1U or 2U server chassis?

Yes, the 40 by 28 millimetre dimensions match the slim profile required for 1U and 2U rackmount enclosures.

How is the fan mounted and which orientation mistake reduces airflow?

Four corner screw holes secure the frame; installing it with the label side facing the wrong direction reverses the intended airflow path.
