Found this handy little guide on another forum in helping to cool your CPU by a fair few degrees for those of us using Win2k or XP. As the progs ones out there at the moment are all aimed at Win9x & don't help cool the NT-based OS's, eg. CPUidle/Hmonitor etc.). This is for the VIA KT266 chipset though (sorry). Take a look. Click here for the guide.... (ps. I'm just showing this link to someone else's work as it maybe helpful to someone here, ie. I'm not trying to take any credit for the author's work).
I'm gonna try it out when I get my T-Bird here shortly (tommorow or thurs). I ought to post this tidbit of info on the main page.
