239940 2004-05-28 05:29:00 Greetings,

Ive finally found the cause of all my crashes with my laptop:
Overheating CPU!

It gets to around 57 - 60C degrees before the fans kick in... and that's just too hot, and programs start segfaulting etc.

Basically, Ive been using gkrellm (http://www.gkrellm.net/) to monitor the CPU, and I've been running:
cat /dev/urandom
to add load to the CPU (And I've also been using cpuburn to do the same job but without the random output to the terminal).
I find that the fans kick in way too late.

Is there any way in Linux and in Doze that I can make the fans kick in faster, say, at 50 degrees?

Many thanks


Chill.

239941 2004-05-28 08:00:00 SppedFan (www.almico.com) This one should do it in doze. Can't see any info on whether it has been ported to linux though.

I used to run it a while back on a dodgy board that was always hot and crashing. Seemed to do the trick on the hot side of things but couldn't make it a better board ;)

239942 2004-05-28 08:07:00 If there isn't a setting in the bios I would say there was a fault somewhere as the fan should kick in well before then. Have you tried a different fan yet. mikebartnz (21)
239943 2004-05-28 08:11:00 The fan control is likely to be hardware. That means a temperature controlled switch on the CPU heatsink. In such cases there is no programmable control. Replacement hardware is called for. godfather (25)

pardon my lack of overheating knowledge...

Segfault or segmentation fault is very basically what Linux programs can do when they lose the plot and terminate for whatever reason. In Chill's case, it is his CPU overheating which affects its performance. If you start up a app from a console window and it segfaults on you, the returned output is displayed with the segmentation fault error. Not something you like to see :p

239947 2004-05-29 09:32:00 Chill here is what I did to cool my cpu
Get rid of noisy oem cpu fan and grab an old psu fan, set it up to blow onto the oem cpu heatsink and try it @7 volts, + to psu yellow wire and - to psu red wire. Either mount it onto the cpu heatsink or make some kind of bracket so it blows over heatsink and towards an extra case fan also @ 7 volts.
Works sweet.
