Thermal Throttling on i7-8750H on HP Pavilion Gaming Laptop 15-cx0020nf

HP Recommended
Pavilion Gaming Laptop 15-cx0020nf
Microsoft Windows 10 (64-bit)

Hello,

 

I Made few test with intel XTU utility (XTU bencmark) and on this laptop I get thermal throttling on the CPU and high températures (95°C max).

Even with undervolting core & cache with -150mV the "problem" is still there and the CPU is reducing his performance when overheating.

 

I would like to know if you have any suggestions about which thermal grease I can use to replace the original thermal paste on the CPU ?

Do you know if the cooling system is made of cooper or aluminum ?

If this is cooper, can I use some metal liquid thermal paste like Thermal Grizzly Conductonaut ?

 

Thanks 🙂

@Nonororo Welcome to HP Community!

 

I understand that the Thermal Throttling on i7-8750H on HP Pavilion Gaming Laptop 15-cx0020nf.

 

HP will not recommend to apply the thermal paste. It will void the warranty.

 

I have a few steps to resolve this issue:  

Symptoms of heat issues and causes of excessive heat  

The following list describes some of the issues caused by overheating in the notebook:  

  • Games stop responding during play.  

  • Windows stops responding during use.  

  • Fans inside the notebook become louder because they are spinning faster as the laptop gets hot, to remove the heat.  

  • When starting the laptop, it sometimes stops at a black screen and does not open into Windows. Windows usually stop responding when it does open.  

The following list describes some causes of excessive heat:  

  • Dust inside the laptop.  

  • A new component, such as a hard drive, is added. The extra component causes the power supply to work harder and generate more heat. Extra heat also radiates off the new component and adds to the temperature inside the case.  

  • Over time, some cooling fans might slow down and wear out, as the laptop is getting hot, depending on the usage of the laptop.  

  • High ambient room temperature.  

Step 1: Removing dust and lint by cleaning vents  

Step 2: Ensuring proper space for ventilation  

Step 3: Updating the BIOS  

Step 4: Using HP CoolSense technology  

Step 5: Placing the notebook in a cooler room  

Step 6: Testing for hardware failure  

If the hardware has failed, capture the failure ID and revert for further assistance.  

 
If the Fan is Noisy and Spins Constantly, PC is Warmer than Normal: Click here for more details.

Hello Praveen196 and thank's for your answer 🙂

 

Indeed it may not be a good choice to try replace thermal paste at this point and to not void the warranty.

For now I have a preset installed with the program throttlestop (-125mV for cache & -150mV for cpu core).

 

I have encountered small "game stop" during few games of starcraft 2 on this notebook I will try to desactivate throttlestop to see if this is still happening.

 

This notebook has not been used many times since we bought it (it must have about 100h of utilisation), we do always take care of the computer, there is no dust inside the laptop, and the ambiant temperature of the room is between 20° - 26°C for now. We have not added any composant inside this notebook, the bios has been uptaded with HP support assistant.

 

I haven't tried HP coolsense technology yet, I will give it a look !

Sorry for my english (french here) I should have used french forum^^.

 

I think the cooling system for this notebbok is a little to light but I will try with HP coolsense !

 

Edit : I figured HPcoolsense was already running on this notebook
