Downclock CPU reaching critical temperature
- by Draga
I have an HP tx1250 laptop. It always had serious overheating problems and although usually it runs fine I'm now running a continuous test for my dissertation, this brings the CPU temp close to the critical and from time to time the computer shutdown for reaching it (checked the log).
I use to have the same problem on Win XP but I noticed Win Vista and 7 downclock the CPU when is necessary to cool it down so I was thinking if the same is possible on Ubuntu 12.
The only program I've found that may do the job is computer temp ( http://computertemp.berlios.de/ ) but it doesn't seems to work under Ubuntu 12.
The inside of the laptop is fairly clean, the thermal paste is quite recent, I'm keeping it lifted from the desk and judjung by the sound of the fan that's running fine as well. The pc in now running between 78 and 91 degrees C but about once a day it shut down for reaching 95. I need the results of the test it's running pretty soon so it's important that it runs non-stop.
I've though to set the maximum clock of the CPU to slightly less the maximum but then these tests I'm running would take much more time.
Thanks!
PS: first and last HP laptop for me.
