extreme temperature

#1 Post by nrj45 » Tue Jan 10, 2006 2:32 pm

Hi,
just to show you that my t43p was running stable at very high temperatures (i forgot to shut down the fan control before gaming and suddenly i felt that my keyboard was becoming very hot...).

Here are the temps :
[10.01.2006 19:36:45] Fan: 0x00 / Highest: 93°C (90 73 57 93 44 n/a 30 n/a 73 71 66 n/a)
EDIT :
BTW, i'm using CHC to undervolt the processor and the "thinkpad t43 fan control" to enter my own fan scheme according to the temperature. But when a game takes 100% cpu, the fan control utility crashes, and letting the fan off.

wow. 93°C. the maximum operating temp. of pentium m is around 100°C although realistically it could probably take more.

That's actually the full load temp I'm experiencing while gaming if I don't undervolt. Stock cooling and gaming at full throttle will put me in the 90's C.

According to the sources I've seen the thermal throttling should kick in around 94 C and at 99 C the processor shuts down to protect itself.

I don't know my temperature and don't want to know most of the time. Never had the CPU shutdown/hang, and the chassis never feels anything over "warm".

Not me. I have to know the temperature at all times (which is why i run the excellent Centrino Hardware Control). I normally undervolt and underclock the CPU and GPU when on batteries which improves battery life and decreases temperature. I get around 40°C under load. When on AC I just undervolt and get in the high 40's under load.
