Undervolting a laptop

Conclusion

Undervolting is, as our tests prove, an excellent way of lowering the temperatures in a laptop. And because we’ve lowered the temperature of the CPU, other components will be a lot cooler because they aren’t affected as much by the heat from the CPU. You get a cooler system with longer battery time and if it is performed correctly, you won’t suffer any stability problems.
You can, as we’ve shown, also set different clock frequencies that the computer can “throttle” between. I not only use the factory defaults of 800 MHz and 1600 MHz, but have also added a middle-clock frequency of 1200 MHz. I can use this when I don’t think 800 MHz does the trick. Of course you can perform the same settings on a regular desktop computer where you can lower the power consumption and thus lower the heat development. But the effect is not as striking in spacious chassis, and you’re not dependent of a battery in a regular PC.

For those of you who are still unsure of the pros when undervolting, we’ve compiled a list below. We have yet to find any cons, because as long as you evaluate the correct settings there shouldn’t be any.

Pros:
+ Lower processor temperature
+ Lower system temperature
+ Longer battery time
+ More settings (Throttling)

Cons:

After writing this article, my hands don’t feel as warm as they would have if I hadn’t performed the undervolting of my laptop. That’s all from me, good luck with the undervolting!
