One P-core hotter than others P-cores

[kokodzambo]

I have one problem with my new laptop that causes my cpu to thermal throttle. I have intel i5 13500H cpu with 4 P-cores and the 4th one  is always 10+ celsius hotter under heavy load than the other P-cores. I tried some benchmarks and P-cores 1,2 and 3 were around 80-87 celsius but the 4th one was jumping to 97-98 celsius and that caused my cpu to thermal throttle is this normal or is something wrong with my laptop. I'll be happy for any help or solution

Hi @kokodzambo,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

It's not uncommon for different cores in a CPU to have slightly different temperatures under heavy loads, but a consistent difference of 10+ degrees Celsius is noteworthy. This could potentially indicate an issue with thermal distribution or the cooling solution on your laptop.

Here are some steps you can take to address the thermal throttling issue.

• Thermal Paste Check/Reapplication: Ensure that the thermal paste between the CPU and the heatsink is applied properly. Sometimes, inadequate thermal paste application can lead to uneven heat distribution. If you're comfortable doing so, you may consider reapplying thermal paste.
• Cooling System Inspection: Check the cooling system for any obstructions, dust, or debris. Over time, dust can accumulate in the cooling fins or fans, reducing the effectiveness of the cooling solution. Clean the vents and fans to ensure optimal airflow.
• Undervolting: You may consider undervolting your CPU. Undervolting involves reducing the voltage supplied to the CPU, which can help lower temperatures. However, be cautious and make sure not to undervolt too much, as it can lead to system instability.
• BIOS/UEFI Updates: Check if there are any BIOS/UEFI updates available for your laptop. Sometimes, HP releases updates that optimize thermal management and overall system performance.
• Laptop Cooling Pad: Consider using a cooling pad to enhance the airflow around your laptop. This can be particularly helpful if you're using the laptop on surfaces that might impede proper ventilation.

I hope this helps. 
 

Take care and have a good day.

I almost did all of the options that you said, only the thermal paste and the undervolting are left, but I can't do such a thing because I have this laptop signed up for a project called digitálný žiak. The only thing I can do is get the notebook checked at a shop or a service. So I don't know what I should do next. Thanks for helping
