I'm using Ubuntu 16.04 on my MB Pro 2013. Lately, my CPU is throttling to a very low frequency and the fan is running at max whenever I turn on the laptop. It drops down sometime but after a few minutes start throttling again.
After running lm-sensors it looks like some of the sensors are reporting -128C as temperature which makes the governor kick in and start throttling the CPU.
Is there any way I can disable these faulty sensors or write a fake valid value to them so that the system thinks everything's alright? I don't care about potential system damage since this laptop is already unusable in this state.
