If the program runs on other notebook systems let me know !

If you've still problems with it, then please ask me only if you have problems using it on an Inspiron 8000/8100/8200 (my testing environment). If you have different hardware try asking on the I8kfanGUI forum or in the appropriate Dell Inspiron/Latitude Forum.


Fan control for other operating systems

  1. A FreeBSD/NetBSD/OpenBSD version of the original DOS i8kfan command line tool ported to *BSD by Damir Lampa (unfortunately the link is dead)
  2. Since Linux kernel 2.4.15 there's also a kernel module written by Massimo Dal Zotto to get access to the important SMM functions under Linux. The tools to access that driver are here:

    http://www.debian.org/~dz/i8k/

  3. Here's a daemon called dellfand specifically for the linux 2.6 kernel series:
