SKU CH-TJHM-D7Y5Q

12 V case fan with 40 × 40 × 10 mm frame spinning at 7000 RPM

  • Compact 40 mm square fits tight server chassis
  • 7000 RPM delivers strong airflow for dense builds
  • 12 V 0.1 A draws minimal power from system supply
  • 10 mm slim profile suits low-clearance 1U racks

Compact 40 mm server fan

This 40 x 40 x 10 mm case fan runs on 12 V at 0.1 A and spins at 7000 RPM. It is built for tight server and workstation chassis where a low-profile 4010 form factor is required.

Replaces worn 4010 units

Swap this in when an existing 40 mm fan becomes noisy or fails, restoring original airflow in the same mounting pattern. The jump is worth it only if the system needs a direct 12 V 0.1 A replacement with identical dimensions.

Questions about this item

Will the 40x40x10mm frame fit my 4010 mounting holes?

The 40x40x10mm frame matches the 4010 form factor, so standard 40mm square mounting holes accept it directly.

How do I connect the 12V 0.1A leads without reversing polarity?

Connect the red wire to +12V and the black wire to ground; the 0.1A draw is low, but reversed polarity will prevent the fan from spinning.
