Heat sink and thermal sensor...

I have a Mid-2012 MacBook Air that is doing the kernel_text 600%+ thing. I ran the diagnostics and received this code: 4SNS/1/C0000008: Th1H—124

Everything I’ve read tells me that code represents the heat sink. Other articles I’ve read tell me that it is a heat sensor. This thread in particular dissects the code: Test give me this error: 4SNS/1/C0000008: Th1H - - 124

And this article talks about ways to get around the sensor:

I am wondering something. If I go through the trouble of buying and replacing the heat sink, will that solve the problem? It doesn’t seem to me that it will, since the heat since does not appear to have a sensor component on it. It looks like just a heat sink: MacBook Air 13" (Mid 2011-Mid 2012) Heat Sink

If so, then where is the sensor indicated in the code 4SNS/1/C0000008: Th1H—124? I can replace the heat sink, but if I can’t also replace the faulty sensor, I won’t have achieved anything.

Thoughts and insights are appreciated.

You’re right, there’s no sensor on the heatsink, avoid wasting time and money on a replacement. Unfortunately there’s no physical sensor that can be replaced either, most likely it’s some component failure that needs to be troubleshooted. Either you’ll have to dive for some time into schematics and probing or get your board fixed by a lab into component level repairs.

So the fast answer for somebody who doesn’t have access to micro-soldering is simply to replace the logic board. And that doesn’t feel very cost effective.

I’ll try the weird software bypass until I’m ready to get a new laptop.


Removing the .kext will silence your fans, but will remove fan controls too and won't solve your issue. Remember to use at least a fan control utility to avoid toasting your board.

The error 4SNS/1/C0000008: Th1H—124 on a Mac Air is a SMC chip error. Unlike a MacBook Pro which has a sensor your system does not. Here’s another person how had the issue and as you can see in pictures there was corrosion on the logic board: CPU throttling sensor error code: 4SNS/1/C0000008: Th1H- -124
