Welcome to the HP support community.

I understand that you are getting a 90B system fan error on your notebook, I am glad to assist you.

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.  

Keep me posted.
