SKU CH-368S-E93V5 MPN 1204KL-01W-B39

A 30 mm DC fan spins at 7500 RPM to deliver 2.7 CFM at 21 dBa for compact 5 V cooling

  • Quiet operation at 21 DBa for low-noise builds
  • 5 V 0.13 A draw keeps power use minimal
  • 7500 RPM speed delivers 2.7 CFM airflow
  • 30 x 30 x 10 mm frame fits tight 3 cm slots
  • 3-wire DC connection enables speed monitoring

Compact 30 mm 5 V DC fan

The SXDOOL 1204KL-01W-B39 is a 30 mm square, 10 mm thick case fan designed for tight spaces such as small-form-factor chassis or hard-drive coolers. It runs on 5 V DC at 0.13 A and connects via a standard three-wire lead.

Low airflow at high speed

At 7500 RPM the fan delivers only 2.7 CFM with a wind-pressure rating of 116, so it suits spot-cooling tasks rather than full-case ventilation. Noise is listed at 21 dBA, which remains quiet for the rotational speed.

Three-wire 5 V requirement

The unit needs a 5 V three-pin header; it will not work from a 12 V fan connector or a four-pin PWM header without an adapter. Buyers without a 5 V header on their motherboard or controller should look elsewhere.

Questions about this item

Which voltage version should I pick for a 5 V header?

This model is rated for 5 V and draws 0.13 A, so it connects directly to a standard 5 V three-pin fan header without any adapter.

What does the 7500 RPM rating mean for airflow in a tight chassis?

At 7500 RPM the fan delivers 2.7 CFM with a wind-pressure figure of 116, giving focused airflow through restrictive spaces such as HDD cages or slim enclosures.

What connector does the 3-wire lead use and what control does it allow?

The three-wire lead fits a standard 3-pin DC header; the motherboard can monitor speed via the tach signal but voltage control is the only way to adjust fan speed.
