The laptop I use day to day is a Lenovo x121e. It’s a nice comprimise between a netbook-like form factor but laptop grade power. It has the same size and resolution screen as a MacBook air so I usually use it coupled with my 22″ external monitor. As good as it is, I’ve been noticing a problem with it recently.
It runs hot. Very hot. I have the laptop propped up at an angle to make it easier to type, which also increases airflow, but while writing this the temperature of the CPU is still hovering around a toasty 77C. The application I’ve included a screen grab of is ThinkPad Fan Control – An application commonly used to turn off the fans so the laptop runs quieter. I actually downloaded it to turn the fans up so I could try and cool the machine down. While playing games I’ve had the laptop randomly shut down, after feeling the underside, I can only assume this is due to the heat and it’s been automatically shut off for safety reasons.
I’ve taken the back off to ensure the fan is clear and no debris is blocking air flow. My next idea would be to try and re-apply thermal paste to the CPU, but I wouldn’t want to make anything worse!
