Compact 40 mm server fan for tight enclosures

This 4010 case fan measures 40 by 40 by 10 mm and runs on 12 V power with a 0.8 W draw. The 412F/2H model targets servers, inverters and other equipment that need focused airflow in a very small footprint. It suits builders replacing a noisy or failed original cooler in a 1U chassis or similar confined space.

Direct swap for worn 4010 units when noise

The fan replaces an existing 40 mm frame that has become loud, slow or unreliable after continuous duty. The jump is worth it when the original cooler can no longer keep internal temperatures stable under load. Buyers who need a larger frame, higher voltage or different mounting pattern should look elsewhere.

Questions about this item

What are the exact mounting hole dimensions for the 40x40x10mm fan?

The fan measures 40mm by 40mm with a 10mm thickness, so mounting holes follow the standard 40mm square pattern used for 4010-size fans.

How do I connect the 12V 0.8W fan, and what polarity mistake should I avoid?

Connect the two leads to a 12V DC source; the 0.8W rating means low current, so reversing positive and negative will prevent the 412F/2H model from spinning.
