Ok, I did a quick replacement of the CPU fan and the temp dropped to 50 degrees Celsius. My Raq 4 never sent me any emails on this. Time for a perl script to watch this.
You might want to look at http://www.dogsbody.org/web/temp_monitor.html It works great on my Raq4, Qube 3 & Qube2 Hope this helps, Dan -- http://www.dogsbody.org/
