Compact 40 mm server fan

The SXDOOL 1204PQB1-8A is a 40 mm case fan built for 1U and 2U server chassis where space is tight and airflow must stay high. It runs on 12 V power and draws 2.6 W while spinning faster than 7000 RPM to move 15 to 20 CFM through dense component layouts.

Double ball bearing and three pin control

A double ball bearing gives the fan a rated 100 000 hours of continuous operation and supports speed monitoring through the standard three pin connector. The motor tolerates a working voltage range of 4 V to 13 V so it keeps running even if rail voltage drifts.

43 dBA at 9000 RPM peak

At its 9000 RPM maximum the fan produces 14.5 CFM with 0.45 in H₂O static pressure at 43 dBA, a level that suits rackmount gear but exceeds typical desktop noise limits. Buyers who need quieter office cooling should look elsewhere.

Questions about this item

How long do the double ball bearings last before they need replacing?

The double ball bearings are rated for 100,000 hours of sustainable operation.

What limits continuous running at the highest speed?

The fan runs at up to 9,000 RPM with a working voltage range of 4V to 13V and draws 2.6W.

How loud and hot does it get when running all day?

Noise is rated at 43 dBA; the motor consumes 2.6W at 12V, so heat output stays low.
