|it depends on the cpu and laptop. Not all cpu's and laptops are created equal. Gaming laptops for example have overclocking options in the bios that allow you to overclock the cpu. Secondly all modern cpu's have thermal monitoring built in so it will keep the temps in check to make sure it doesn't get overheated and reach it's max TDP before shutting down. |
The Core i mobile series are diff beats. For one they are preoverclocked by intel with turbo mode which is designed to not effect temps all that much when turbo mode is active. Even if the user decides to overclock a Core i series mobile cpu there is room to do so without it effecting your temps that much within reason. Take for example my Intel 720QM I was able to overclock it from 1.6ghz quad core mode to 1.8ghz with a turbo mode frequency from 2.8ghz single core to 3.1ghz which puts it in the 840QM range in performance, while still maintaing temps of a 5c difference between stock and overclocked which is well within my TDP range. It just all depends on what type of cpu you have in your laptop and how good your cooling is on your laptop to determine how well and effective your overclock can be on your laptop while maintaining a good temp.
The down side to overclocking a laptop is even if you have a capable laptop with good cooling to overclock with, you will drain the battery life even faster when overclocked. Now if you have a gaming laptop, and overclock your cpu it doesn't really effect your battery life considering the vast majority of gaming laptops have poor battery life from the get go at stocks speeds anyhow due to the high powered hardware, but with normal mainstream laptops it can which is something you have to keep in mind.
