Laptop Fan Not Working

[Conner8]

Laptop fan does not work whatsoever, averages mid 80s without load, 15-fd0000 series

Cleaned fans earliertoday with a Q-tip and unused dry paintbrush because I didn't have compressed air, under medium load the CPU can reach 100c, and I do not hear the fans whatsoever at all

@Conner8,

Firstly, cleaning with a Q-tip can sometimes accidentally jam or damage the fan blades/bearing, especially if the fan was spun manually during cleaning.

If temperatures are already reaching 100C under moderate load, I would absolutely avoid gaming or heavy use until the cooling issue is resolved because prolonged thermal stress can damage the motherboard or CPU.

To make sure you order the correct cooling fan, you should first identify the exact fan assembly currently installed in the laptop.

The HP 15-fd0000 series has multiple thermal configurations, so ordering by "15-fd0000" alone can result in the wrong fan.

I would recommend:

1. Get the full product number
   (example: 15-fd0xxx)

You can find it:

• on the bottom label,
• inside BIOS (F10),
• or in HP Support Assistant.

1. Remove the bottom cover carefully.
2. Locate the cooling fan assembly.
3. Read the exact spare part number printed on the fan label itself.
   HP usually prints something like:

• SPS: N38472-001
  or similar directly on the fan.

This is the safest and most accurate method.

1. Also verify:

• number of fan connectors,
• fan shape,
• heatsink layout,
• and screw positions.

Some versions use:

• integrated graphics cooling,
  others:
• discrete NVIDIA GPU cooling.

The assemblies are not always interchangeable.

1. While inside:
   check whether:

• the fan cable is disconnected,
• debris is blocking the blades,
• or the fan is seized.

If the fan does not spin even briefly during startup, replacement is very likely needed.

Already decided on avoiding heavy tasks or prolonged use. Q-tips were quickly abandoned and I used a fine paintbrush for most of the job. Its gonna be replaced, because even with the 'fan is always on' setting in BIOS, I hear nothing

@Conner8,

Do you need help finding the cooling fan's part number?  If so, please provide the full product number and specifically the #ABA model number.
