DBTLAP

DBTLAP 120x120x32mm 12032 DC12V 3.39W 4 Lines pwm Centrifugal Turbo Blower Cooling Fan

SKU CH-96N0-55YYA

A 120 x 120 x 32 mm DC 12 V centrifugal blower with 3.39 W PWM control for targeted laptop cooling

  • Accessory TypeCooler
  • PWM speed control matches cooling to demand
  • 12 V DC power suits laptop cooler boards
  • 39 W draw keeps energy use low
  • Centrifugal blower design pushes air through tight vents
  • Pre-tested unit ships ready for drop-in replacement

Replacement Centrifugal Blower Fan

This DBTLAP cooling fan is a direct replacement part for laptop cooling pad model PFC0321B3-C03U-S9D. It suits repair technicians and owners who need to restore original airflow performance. Each unit is tested before shipping to confirm operation. Buyers who want a universal fit kit or additional mounting hardware will not find those items here.

120x120x32mm Form Factor With Four-Wire PWM

The fan measures 120 by 120 by 32 millimetres and uses a four-line PWM connector for speed control. Its centrifugal turbo blower design directs air through a focused exhaust path rather than an open axial flow. Matching the original part number is essential because connector pinout and housing tabs vary between revisions. No screws, brackets or adapter cables are included in the package.

12 V DC Operation At 3.39 W Power Draw

The blower runs on 12 V DC and draws 3.39 W under normal load. PWM control allows the host system to modulate speed for thermal balance and acoustic comfort. Centrifugal geometry typically sustains static pressure better than axial fans at equivalent power. Users seeking lower voltage options or higher wattage headroom must source a different specification.

Questions about this item

What does the 4-line PWM interface control on this 12032 blower?

The four-wire PWM connection carries power, ground, a tachometer signal and a speed-control line so the host system can regulate fan RPM precisely.

What physical clearance does the 120×120×32 mm frame require?

The square 120 mm footprint and 32 mm thickness need an exact matching cut-out and screw-hole pattern in the laptop chassis or cooling pad.

How is the centrifugal blower installed and which step is often missed?

Remove the old fan, align the four mounting holes, connect the 4-pin PWM plug, then verify the blower spins freely — many forget to re-seat the connector fully.
