undervolting my laptop

[hzk012]

my laptop is overheating everytime i do simple task such as web browsing and etc. ( light stuff ). i already clean the fan and repaste the cpu. but sometimes its still overheat. i look up at the internet on how do undervolt ivy bridge mobile cpu but i cant find it. ny question is, can i undervolt this laptop and if can how ?

No but you can reduce the maximum processor state in power management. Advanced power options. Maximum processor state is currently set to 100%. Try reducing it to say 90%. Try various settings until it cools down but is still useable. This is a desparation move, by the way. There is some kind of underlying problem with the CPU or the motherboard. This will mask the problem.

Is the heat coming from the CPU, or from the disk-drive?

Google-search for "download free SPECCY".

Download, install, and run this software.

It will report on the speed of the fan(s), the temperature of the disk-drive, the temperature of the CPU, and the temperature of the motherboard.

Also, when it is "hot", shut it down, remove the battery, disconnect the AC power, and open the access-door covering the disk-drive.  Check the temperature of the disk-drive.  If it is "hot", consider buying & using a SSD ("Solid State Drive"), which should run at a lower temperature.

It's coming from the CPU, 70-80 degree Celsius ( 158-176 Fahrenheit)

That is much too hot!

It should be in the 25 to 40 degrees Celsius range.

Take your computer to a qualified technician for a "cleaning", and to confirm that the internal fan is working.

SPECCY should tell you the speed of the fan  ?!

But, can you undervolt the laptop ? Or you just can't ?

Back to that, huh? Setting the processor maximum state does essentially the same thing but no you can't undervolt it as you can on a desktop with advanced BIOS adjustments. Can you imagine the warranty implications if you let people adjust the processor voltage on their laptops? Try what I suggested.

I definitely agree.  To repeat: take it to a qualified computer technician, to investigate the over-heating.

70 - 80c is okay if your running a gaming grade laptop. above those temps would be a worry.
If you have fan profiles then maybe change it to on that has a higher speed
