Hello abhishek4124,

Thank you for sharing your concern.

If your OMEN 17.3 inch Gaming Laptop PC 17-ck1000 is experiencing issues with the fans not functioning properly even after replacement, it could be due to a few different issues. Here’s a detailed approach to troubleshoot and possibly resolve the problem:

Check BIOS/UEFI Settings:

Access the BIOS/UEFI settings by restarting your laptop and pressing the appropriate key (usually F2, F10, or Del) during the boot process. Look for any fan settings and ensure that all options related to fan speed and thermal management are set to default or optimized settings.
Update BIOS:

Ensure that you have the latest BIOS version installed on your laptop. Visit the HP support website to download and update your BIOS to the latest version which may include fixes for fan control issues.
OMEN Command Center:

Open the OMEN Command Center and try performing a system diagnostics check specifically for fans and thermal management. Ensure that the software is up-to-date as it might require an update to function correctly.
System Temperature:

If the system temperature exceeds a certain threshold, the fans should start spinning. Verify that temperatures in the OMEN Command Center are reading accurately, and if not, you might have a sensor issue.
Software Interference:

Third-party software can sometimes interfere with fan operation. Try booting into Safe Mode to determine if a software conflict is causing the issue.
Battery and Power Supply:

Sometimes, issues with the power supply or battery can affect fan operation. Ensure that your power adapter and battery are functioning correctly.
Reinstall or Update Drivers:

Reinstall or update your system’s chipset and thermal framework drivers through the HP support website or Device Manager.
Contact HP Support:

If these steps do not resolve the issue, and since a technician has already replaced the fans, it's advisable to contact HP support again or take the laptop back to the service center. There might be an underlying hardware issue, such as a problem with the motherboard or fan controller, which needs professional repair.
