Predator 17 G9-791 CPU frequency and Fan issues

PredatorG9-791

Hi, I have two issues that developed suddenly one year after using my Predator 17 G9-791 with an Intel i7-6700HQ CPU @2.60GHz.

 

Issue #1: The CPU frequency as reported by Predator Sense has dropped to 800MHz from 2600MHz and the CPU temperature is now showing as 0 degrees celcius. This is clearly shown in the screenshots below:Predator Sense and CPU-Z informationTask Manager

Issue #2: At the same time issue #1 happened, the internal fan started to work continuously at maximum speed from the booting till the laptop is turned off.

 

I reported these issues to Acer Technical Support who asked for the laptop to reset to Factory image. This was done without any success. All new updated drivers were also installed but this remained the same. They then asked for the laptop to be sent to them, only then to be told that the system was normal after they ran full stress tests on it for 48 hours. I received the laptop but the same issues remain.

 

The laptop does not show any high temperatures as it's been in the same location for the past year and used on daily basis without any problems before these two issues.

 

Any advice, solutions and/or recommendations would be appreciated.

 

Thank you.

You're experiencing Thermal Throttling. The most common cause is when you're laptop overheats. Did your laptop suddenly turned off while you were using it then when you turned it back on this issue occured?

 

However, whatever the cause is, use this as a temporary solution:

 

1. Download ThermalStop.

2. Turn BD PROCHOT off.

 

After doing these two steps, your laptop's clockspeed should go back to normal but it won't solve your fan running at maximum speed. 

 

I experienced this problem before (although my laptop didn't overheat), and I sent it to a technician. I wasn't billed because they told me it was a driver problem and they solved it simply by updating the Thermal Control drivers. 

 

(I cannot believe Acer support wasn't able to remedy the problem you had, when I brought my Predator laptop to Acer they solved this problem is less than two hours.)
