40 mm square DC cooler for compact builds

The OEM Industries A4010H05S is a 40 mm square fan designed to provide direct airflow over small-form-factor CPU heatsinks. It operates on a 3.3 V supply drawing 0.20 A through a two-wire, two-pin connector. The sleeve bearing keeps acoustic output low in space-constrained chassis where larger coolers cannot fit.

Capacity and headroom within a 4010 frame

At 40 mm by 10 mm the fan moves enough air for low-power processors and embedded boards that stay within modest thermal envelopes. Headroom disappears quickly when sustained loads push package power beyond what a single 4010 unit can dissipate. The two-pin header offers no speed reporting or PWM control, so airflow remains fixed regardless of temperature.

Replaces worn or missing 40 mm two-pin fans

This unit serves as a direct drop-in replacement for failed or noisy 40 mm sleeve-bearing coolers that use the same 3.3 V two-pin interface. The upgrade is worthwhile when the original fan has seized, developed bearing rattle or no longer spins at rated voltage. Builders who need variable speed control, higher static pressure or a larger mounting footprint should look elsewhere.

Questions about this item

Will the 40 mm CREATE-FLOW cooler fit the 40 mm mounting holes on my older motherboard?

The cooler is a 40 mm square frame, matching the standard 40 mm mounting pattern found on many legacy boards.

How can I confirm the 3.3 V 0.20 A fan is spinning correctly after installation?

Connect the 2-pin header, power on the system and verify the blades rotate; the rated current is 0.20 A at 3.3 V.

Does the package include mounting screws or a 3-pin adapter for the 2-pin connector?

The unit is supplied as the fan only with two wires and a 2-pin plug; screws and any adapter must be sourced separately.
