Resposta para "Fan running at full speed, CPU throtled"Here is a photo of my temperature readout. The 128C is what the system is saying, which is nonsense as the air from the fan exhaust is cool. The two other temperatures are from an app called Temperature Gauge 4.1 which is set to give CPU 2 Core and CPU PECI temperature sensor readings.
Resposta para "Fan running at full speed, CPU throtled"I have a more cynical and conspiratorial answer to this. I have exactly the same problem with my 2012 Macbook Pro. However, this only happened after my machine would not switch on at all. I was told that maybe taking the back off and disconnecting the battery for 60 seconds would solve the problem, which it did. My Macbook started up with the power button for the first time in weeks, and I was very grateful..... That is until I realised the computer no longer recognised the battery, the fans suddenly started doing 6200rpm, and something called kernel.task was using 300% CPU time, resulting in my machine now being mega-slow. Apparently this is a panic reaction to temperature sensors reaching 100C or thereabouts and designed to prevent the user from commencing any activity which might push the temperatures any higher. All very logical you might reply, but I do not believe this was just coincidence. After all, I paid for my laptop years ago, and it is well out of warranty. If I choose to fry my CPU, or...
