Fans KD1209PTB2Size 90x90x25mm 12V 2600rpm case fan

SKU CH-GJ5Z-V2A9R MPN KD1209PTB2Size

A 90×90×25 mm case fan runs at 2600 rpm on 12 V while producing 18 dBA

  • Low 18 dBA noise for quiet operation
  • 2600 rpm speed delivers strong airflow
  • Magnetic suspension bearing reduces friction and wear
  • Compact 90x90x25 mm fits tight builds
  • 12 V 1.7 W draws minimal power

Compact 90 mm square frame

This 90 x 90 x 25 mm case fan fits tight chassis where larger units cannot. It targets builders who need directed airflow in small-form-factor or industrial enclosures. The magnetic suspension bearing reduces friction for consistent rotation. Buyers who want more storage or multiple drive bays will find the frame too small for high-volume cooling.

1.7 W draw at 2600 rpm

At 12 VDC the motor draws 0.3 A and delivers 2600 rpm with a rated noise of 18 dBA. The low power figure leaves headroom on modest fan headers. It runs out when static pressure must overcome dense radiator fins or long duct runs. Systems needing higher airflow density will exceed the comfortable envelope.

Magnetic suspension bearing only

The bearing choice removes oil-migration wear and keeps acoustic output steady over time. No speed-control cable, RGB lighting or mounting hardware are mentioned in the data. Installers must supply their own screws and any PWM or voltage-regulation wiring required by the motherboard header.

Questions about this item

Will the 90x90x25mm frame and 12V connector fit the mounting holes and header on my older motherboard?

The fan uses a standard 90mm square frame with 25mm thickness and runs on 12VDC, matching the common mounting pattern and voltage header found on most legacy boards.

How can I confirm the magnetic suspension bearing is running at the rated 2600rpm and 18dBA after installation?

Check the RPM reading in BIOS or fan-control software against the 2600rpm spec, and listen for the low 18dBA noise level that characterises this bearing type at full speed.

Does the package include only the fan or are mounting screws and a power adapter also supplied?

The unit is supplied as the fan motor alone; mounting screws and any required power adapters must be sourced separately.
