CPU temp getting to high?

The machine will work as a server that is always turned on. It has to be stable. Using mbmon, I notice that the CPU fan constantly works at 2700rpm, regardless of the CPU temperature. The temp starts at about 50七/120了, but when stressing the machine a bit it quickly exeeds 90七/195了. The only way I have made the fan speed change, is by using the "AI Quiet" option in BIOS. But it just started at 1000rpm, worked its way up to 2700rpm after some minutes, and stayed there while the temperature was rising much higher. I have upgraded to the latest BIOS and reset the settings, and also tried the Q-Fan option. Nothing worked. What does this mean? Is 2700rpm the maximum for my fan? Are degrees over 90七/195了 unhealthy for the computer? Any way to get the speed to increase more properly? Here is my dmesg: http://axel.pusen.org/dmesg.txt And here's the output of sysctl -a: http://axel.pusen.org/sysctl.txt Thanks in advance! -- Axel
