Ask HN: Tips for overheating laptop running linux

Posted by giis on Saturday November 21, 2015 @07:57AM
from the ask-hn dept.

I brought a AMD-A10-7300 CPU laptop running centos. Problem is heats up in 20 minutes. Virtually, finger are burning. Just ordered a cooling pad. Considering the fact, I'm running Linux, Is it possible to tweak some kernel module or stuffs like that to reduce the heat? any thoughts?

EDIT : I removed to Gnome-3 and installed MATE desktop.

Is it second hand ? You could open it to see if the fan is still working or if there's an accumulation of dust.

No, this was new laptop. Just 2 months old.

Note to all: thanks for the response, sorry for the delay.

good comments by all here i agree with jmnicolas. probably an accumulation of dust in the fan and its casing. most likely cause of over heating problem or perhaps the fan is dead. cpu governors could also be an issue. so i suggest check govener first as it is easy to check then get your screwdriver out and the tweezers .

Check you GPU driver. On Ubuntu switching from the open-sourced to the nvidia driver fixed the heating problem.

Currently its running 'On-demand'. I changed it to conservative. Lets see how it performs
