Fan running at full speed, CPU throtled
This seems to be a fairly common issue but with various causes and I can't seem to find the cause on my laptop.
I understand that the fan running at full speed and CPU throttling often point to a faulty temperature sensor.
I'm using the program TG Pro to check sensors, and it's telling me that the HD sensor may not be working correctly. I replaced the SATA cable (where I believe the sensor is located) but no luck. I've tried a different hard drive, a solid state drive, with no luck.
I got fed up and went ahead and replaced the logic board, figuring this would surely solve the issue. Still I'm getting the full blast fan and throttled CPU.
Any ideas? What else could it be? Is there a HD temp sensor that is located somewhere other than the SATA cable, logic board, or HD itself?
I will note that when I boot into safe mode, the fan still runs at full speed but the CPU throttling goes away.
Is dit een goede vraag?
