I have a Lower end ALienware Aurora that has recently started having the fans kick up to amazing heights. I used CPUID HWmonitor and ran Dell's diagnostic tests and during the test (and while playing nearly any game) the Motherboard temp will average out at 103c and spiked to 107c. Seems like everything is running hot and it did not used to perform like this.. not sure what to do.
I haven't changed any voltages or anything since I got the thing.

Here is the info as I idle and write this:

Ever blow the dust out? Those 2 x GT 545 cards don't seem to be hot. But the CPU is too warm. Especially if that is idle temps! Have you checked the cooler to see if it is loose? If the PC has been in use for a couple years, it may be time to replace the thermal paste between cooler and CPU.

Machine was pretty dust free, and all fans working. Replaced the paste... no change. However another suggestion was that the pump on the water cooling went out... replaced it with a corsair h55... works great now
