    You think so?

    Well, maybe so. I still remember seeing 43ºC idle and 80ºC under load when I was in Finland, but, well, the Finnish winter doesn't exactly have 32ºC days like today :)

    You are quite right - it makes sense that using a 65W supply would result in slower processor speeds. I was still a bit surprised as that has not been a problem with earlier XPS or other Latitude machines ... and checking the specifications from Dell they at one point indicates this adaptor works with the E6400.

    Those specs also indicate that the machine should work at temps up to 40C. Most annoyingly in those conditions Acers, HPs and Thinkpads seem to "sweat it out" OK while I am shutting the E6400 down b/c it is unusable.

    Thanks again to everyone for exploring the issue and how to correct it.

    It's really hot today and my e6400 reaching fan 4800rpm speed. Temps are not so higher as usual:

    Sensor Properties
    Sensor Type Dell SMI (ISA B2h)
    GPU Sensor Type Diode (NV-Diode)

    Temperatures
    CPU (T9600) 41 °C
    Chipset 48 °C
    Aux 48 °C
    DIMM 48 °C
    GPU Diode(160nvs) 52°C


    Cooling Fans
    CPU 4835 RPM

    Voltage Values
    CPU Core 0.90v
    Laptop is at light usage. Sometimes I can reset fan with fn+z to 3600rpm, and after not long it goes to 4800. What can be the problem? I tried different bios versions - same.

    So your problem is high fan activity, but there is no throttling?

    Did you try running HWmonitor to see if there are any temperature spikes that are triggering the fans?

    Or you can try the system data hack:
    This may reveal another sensor.

    I agree that there is nothing in the temperature data that should trigger such fan activity.

    Did you try the system data hack (it's not dangerous)? If I recall correctly that shows the sensor values that are used by the BIOS.

    yes, i wonder what sensor 2 it is
    sensor 2 have the lowest critical values (46C)
    p.s. gpu sensor have incorrect data seems so, from cold fast wake up gpu have 44C(41C value from bios), while other components ~33C

    I can throw no further light on this. It might be time to try to find an enlightened person in Dell support.
