As said earlier, our server room is not equiped with the latest and most powerful cooling equipment available. As it is summer in Norway, the temperature in the room could get above 35C. This room is not optimal, but it is the best solution available to me. So, in order to track the temperature changes I have made a quick hack with MRTG, perl and ipmi-sensors to read the temperature from the IPMI 1.5 BMC on the PE2850 and PER200s. The result is available at http://decagon.frode.biz/ipmistat. As you can see, it also displays fan speeds.
