Possible heat pipe failure

[Anthony6575]

Hello, I'm working on a HP Beats notebook after a successful start-up things are working fine and a few mins later the machine will go into locked, black screen, and say system temp is (90D) 

I have replaced new CPU fan, and thermal paste. I suspect the heat pipe is somehow broken, is there a part number from HP or a way to get a new one from HP?

Hi @Anthony6575,

Welcome to the HP Support Community. 

I'd be glad to help you! 

It sounds like you're dealing with an overheating issue, which can definitely be concerning. Let me ask a couple of questions to help narrow things down:

Have you checked if the CPU temperature stays high even after replacing the fan and thermal paste, or is the temperature gradually increasing after a few minutes of use?

When the system reaches the temperature warning, does the fan increase in speed, or does it remain quiet?

Here are a few troubleshooting steps to further investigate and resolve the potential heat pipe issue:

 

• Visually inspect the heat pipe for any obvious signs of damage, bends, or blockages. Since heat pipes are crucial for transferring heat from the CPU to the cooling fins, any malfunction or breakage will significantly impact cooling.
• If possible, gently try to move or wiggle the heat pipe (if accessible) to check for any loose connections. A faulty connection could contribute to overheating.
• Check the airflow around the laptop while it's running. Ensure vents and cooling areas are not obstructed by dust or debris.
• Use a temperature monitoring tool (like HWMonitor or Core Temp) to track the CPU and GPU temperatures during operation. This will allow you to confirm if the temperature continues to rise rapidly, which indicates the cooling system might not be performing optimally.

Test the laptop without the battery (if removable) and connect it directly to AC power to see if there’s a difference in temperature, as sometimes battery-related issues can affect overall cooling efficiency.

These steps should help you narrow down whether the heat pipe is indeed the issue or if there are other factors causing the overheating.
