Without warning, the machine acts like you’ve ripped the battery out. This is what most people think of when you tell them your laptop is overheating. In that case you won’t hear the fan at all, even though your laptop is getting significantly hotter. Some laptops don’t have fans at all, and for those that do, many overheating issues are caused by the fan malfunctioning. Of course, a computer can overheat quietly too. That’s because the hardware is telling the system fans to run faster and more often in an attempt to force excess heat out of the laptop. It’s almost ironic that while the laptop is slowly struggling away as it tries to accomplish basic tasks, it starts screaming like an Airbus A380 accelerating down the runway. If it continued to operate unimpeded and the temperature kept rising, the hardware would become vulnerable to long term damage. The laptop is throttling back the performance of its own hardware to try to bring its temperature back to within a normal range. The reason this happens is simply self-preservation. Even typing or moving the mouse pointer happens more slowly than usual. A hot laptop will run like it’s from 2006. Performance Slows DownĪnother sign that your laptop is overheating is the massive performance drop you’ll notice. If you’re seeing those sort of temperatures, especially when you’re not doing a lot on your laptop at the time, you need to start looking at how well your cooling system is working. Once the mercury rises above 80☌ (175☏) for extended periods, it’s time to start getting worried. If you’re not doing much more than running a word processor or watching a YouTube video in your browser, the laptop’s CPU temp should hover around 40-50☌ (100-120☏.) If you’re gaming or running several programs at once, then 60-70☌ (140-160☏) is an acceptable temperature. You can use a third-party tool to check the actual temperature of your laptop: apps HWMonitor or Open Hardware Monit are free and do a good job. It’ll be blowing warm air around and feel hot to the touch, suddenly going from warming your legs nicely to feeling like you’re being branded. Once your laptop starts overheating, you’ll know it.
