    I've downgraded my Inspiron 1420 recently to XP SP3 with all the device drivers properly installed. Everything seems works fine except that I found fan1 & fan2 always on at max. high speed (very noisy) and CPU always max. at 1.5GHz (seems lost SpeedStep control, checked enabled in BIOS, with SpeedStep control cpu speed should drop to lower rate while the notebook is idle), the fans and cpu speed status are checked via the utility program I8KFANGUI. If I enabled automatically temperature control in I8KFANGUI then fan1 can turn off as cpu cool down to below 55c and only turn on at Low speed at 60c (still very quiet, noise no noticeable) but still fan2 is always high at 4XX RPM constant rate, I8KFANGUI in fact reported fan2 is not controllable even for just turn on and off.

    I would like to know is there any DELL specific notebook utility for fan & cpu SpeedStep control under XP for the Inspiron 1420 that I need to install in order to get rid of these problems?

    Many thanks for your advices in advanced.

    If CPU Usage is at 100% that is going to drive the temperature up and make the fan run full speed.

    Not CPU usage or load, I mean CPU speed.
