Compact 40 mm CPU cooler

The OEM Industries FD1240-A3033A is a square 40 mm fan unit designed for tight chassis where a full tower cooler cannot fit. It targets builders upgrading small-form-factor systems or replacing a noisy stock blower on legacy hardware. The three-pin connector allows direct attachment to most motherboard headers without adapters.

Thermals noise and power

Ball-bearing construction keeps rotational friction low while the 12 V 0.07 A rating limits power draw to under one watt. At typical speeds the fan moves enough air for low-TDP processors yet stays quiet enough for office or home-theatre use. No LED lighting means no extra glare in darkened rooms.

Single specification that decides fit

The cooler is fan-only with no heatsink base or mounting hardware included. Buyers who need an integrated heatpipe tower or a threaded retention kit for a specific socket must look elsewhere. Verify that your board provides a three-pin header and that the 40 mm footprint clears surrounding components before ordering.

Questions about this item

How do I install the 40mm FD1240-A3033A cooler and what is the step people often miss?

Mount the 40mm fan using the four corner holes, connect the 3-pin header to the motherboard CPU_FAN port, and verify in BIOS that the fan spins at 12V 0.07A; the missed step is forgetting to set the header to PWM or DC mode so the 3-pin fan runs at full speed.

What maintenance or replacement will the FD1240-A3033A need over time?

The ball-bearing fan should be cleaned of dust every few months with compressed air; if noise or vibration appears, replace the entire 40mm unit since the bearing is not serviceable.

What limit appears first on the FD1240-A3033A during sustained use?

The 40mm frame and 0.07A current draw limit airflow, so thermal throttling of the CPU occurs before the fan reaches any mechanical limit.
