Compact 40 mm CPU cooler

The Zyvpee EFB0405MD W310 is a 40 by 40 by 20 millimetre square DC cooler designed for tight CPU cooler mounts. It suits builders working with small-form-factor boards or proprietary chassis where a full-size tower will not fit. The three-pin connector provides simple voltage control on most headers.

Ball-bearing thermals and low power

A ball bearing keeps friction low for consistent rotation and longer service life. The fan draws 0.24 amps at five volts, so heat output stays minimal and acoustic levels remain subdued during typical workloads. No LEDs mean no extra light bleed in dark cases.

Three-pin integration and clearance

The 3-pin power connector plugs directly into standard motherboard headers without adapters. At 20 millimetres thick the unit leaves room for adjacent memory slots or voltage-regulator heatsinks. It is not suited for high-TDP sockets that demand larger heatsink surfaces or higher static pressure.

Spørgsmål om denne vare

How do I install the 40×40×20 mm fan and which step is often missed?

Mount the square frame with four screws, plug the 3-pin connector into the motherboard header, then verify the 5 V 0.24 A rating matches the header limit — many forget to check current draw.

What maintenance will the ball-bearing fan need later?

The sealed ball bearing runs without lubrication; only periodic dust removal from the 40 mm blades is required.

What limit appears first during sustained 5 V operation?

The 0.24 A current ceiling restricts maximum airflow before thermal throttling becomes a factor.
