Hi @Sudheer_P,

Welcome to the HP Support Community. 

I'd be happy to help you! 

If your HP Pavilion Gaming - 15-ec0043ax laptop's cooling fan is making more noise than usual, it could be due to a few possible reasons. Here's how to diagnose and address the issue:

1. Dust and Debris Build-Up:

• Problem: Over time, dust and debris can accumulate inside your laptop, especially around the cooling fan and vents. This can cause the fan to work harder, resulting in more noise.
• Solution:
  • Use compressed air to blow out the dust from the vents.
  • Ensure the laptop is turned off and unplugged before cleaning.
  • If you're comfortable opening the laptop, you can carefully clean the fan and surrounding areas directly.

2. Fan Bearing Wear and Tear:

• Problem: The fan's bearings might be wearing out, especially if the laptop is older or has been used extensively for gaming, which puts more strain on the cooling system.
• Solution:
  • If the fan is failing, it may need to be replaced. This usually requires disassembling the laptop, so if you're not comfortable doing it yourself, consider taking it to a professional.

3. Overheating and High CPU/GPU Usage:

• Problem: If your laptop is overheating due to high CPU or GPU usage, the fan will run at higher speeds to cool down the system, which can be noisy.
• Solution:
  • Check Task Manager: Press Ctrl + Shift + Esc to open Task Manager and check if any processes are using an unusually high amount of CPU/GPU.
  • Close unnecessary applications: especially those that are resource-intensive.
  • Update Drivers: Ensure that your graphics and system drivers are up to date.

4. Fan Speed Settings:

• Problem: The fan speed might be set to a higher profile, especially in performance or gaming modes, causing it to run faster and louder.
• Solution:
  • HP Command Center: If your laptop has HP Command Center installed, you can adjust the fan speed settings to a quieter mode.
  • BIOS Settings: Some laptops allow you to adjust fan speed settings in the BIOS. Access the BIOS by pressing Esc or F10 during startup and look for fan control options.

5. Software Issues:

• Problem: A software or firmware issue might be causing the fan to run at full speed unnecessarily.
• Solution:
  • Update BIOS: Ensure your BIOS is up to date as sometimes fan-related issues are resolved in BIOS updates.
  • Check for Firmware Updates: Check HP’s support page for any firmware updates for your model.

6. Thermal Paste Degradation:

• Problem: The thermal paste between the CPU/GPU and the heatsink may have degraded over time, leading to poor heat transfer and causing the fan to work harder.
• Solution:
  • Reapplying thermal paste requires disassembling the laptop and applying new paste to the CPU and GPU. This is a more advanced fix and might require professional assistance if you're not experienced with hardware repairs.

If you're uncomfortable performing these steps yourself or if the fan noise persists after trying the above solutions, it might be best to reach out to the nearest service center. 

They can properly diagnose and fix the issue, whether it's cleaning, fan replacement, or another underlying problem.

Hope this helps! Keep me posted for further assistance
