30mm mini fan for compact networking gear

The SunnyStar FD0530105B-2N is a 30mm square frame fan designed for tight spaces inside routers, switches or similar embedded devices. It runs on a 5V supply drawing .4W through a simple two-wire lead. The ball-bearing motor targets continuous operation in small enclosures. Builders working on miniature PC projects can also use it where clearance is extremely limited.

Two-pin 5V power restricts motherboard use

The cooler uses a two-pin connector fixed at 5V, so it cannot be controlled by standard four-pin PWM headers found on modern desktop boards. Voltage regulation or speed reporting is not available through this interface. Adapters exist but add bulk that defeats the purpose of the 30mm form factor. Buyers who need motherboard-controlled cooling should look for a three-pin or four-pin alternative.

30mm frame size dictates fit

The 30 by 30 by 10mm footprint is the single dimension that decides whether this fan suits a build. It matches the 3010 mounting pattern used on many router and switch chassis. Any case or heatsink cut-out larger or smaller than this pattern will not accept the unit. Measure the available opening before ordering.

Questions about this item

Which version of the FD0530105B-2N should I pick for a 5V header?

This model runs on 5V at 0.4W with a two-pin connector, so match it to a 5V fan header that supplies at least that power.

What does the 30mm size mean once it is installed in a router or switch?

The 30mm frame fits tight spaces on small boards and moves air across a south-bridge or voltage-regulator area without blocking adjacent components.

What does the two-pin connector cap in practice?

The two-pin layout delivers fixed 5V power with no speed signal, so the fan runs at constant speed and the header cannot report RPM.
