T500 thermal management

2008-09-15, 8:10 AM

I have a T500 with P8400 and integrated graphics. Though the notebook is almost always cold (and in addition I use Thermaltake ixsoft fanless cooling pad) the fan is almost always on (Everest indicates that even with core temps around 30 C). The fan goes off only when it is rather cold (17 C) in the room (using Maximum Battery Life energy profile).

Is this behavior ok?

What is the threshold temp to start the fan?

How can I alter the thermal management? (I tried BIOS and ThinkVantage power management)

Solved! See the solution

Hello,

 

try the little program fancontrol.

or Tpfancontrol from Troubadix.

Hopefully it runs on the newest T systems.

 

Regards

Andreas

Both programs seem to work. Manual control has immediate effects. However - and I find this surprising and puzzling - there is still a fan-like whirring cleary audible which seems to be coming from the rightside of the notebook. This one goes off only when its cold in the room and nothing is done with the ntb. Is there another fan?

It seems that the fan was off even without using these programs, as when the fan speed is set to 0 there is no noise from the top left corner where the exhaust ist.

Well fortunately it is not a cpu whine :) After I played with the power saving settings I am sure  it is the HDD. Gotta solve that now :)
