alienware 046mhw runs crazy hot during idle and especially under load

[xbomb]

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 memory test (and while playing nearly any game) the Motherboard temp will average out at 103c and spiked to 107c. The CPU was at 70c. Seems like everything is running way too 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:

I plan on removing the water cooling and replacing the thermal paste. I looked the fans and heatsink but they seemed to be free of dust.. I will make sure the fans are running when it is on, but the damn thing sounds like a jet liner getting readyto take off so I imagine they are

HELP!

It looks like it's the CPU. The video cards are running normal. If it has water cooling the pump may have quit. It doesn't matter that the fans on the radiator or motherboard kick up if the water isn't circulating to draw the heat away from the CPU. If it doesn't damage your CPU it will likely throttle it down and may even shut it down eventually. Also, check the Southbridge chipset fan if it has one. That may have died but they usually run a little hot anyways and usually large heatsinks are enough for those.

Do you know how I could test if the Water Cooler went out? Should I just replace it?

Replaced cooler with corsair h55... works great now.. Thanks for the suggestion
