Issues with Thermal Controller
SPECS
Aurura
i7 930 @ 3.36GHz
12GB ram
Dual Nvidia GTX 460 SLI'ed
Command Center 2.6.1.0
Just bought a new Aurora and blew away the system reinstalled the OS on an SSD and installed drivers and what not from the Resource CD before I read the forum post that tells us not to install the Command Center off the resource CD.
Now I believe I'm having an issue with Thermal Controller. The temps that it's reporting for the three sensors range from 22C-24C no matter what I do on the computer. However if I run SpeedFan it tells me the three temperature senors are more the range of 27C-44C depending on the sensor with Temp2 reporting the highest.
I've done all the suggested steps for checking to see if the MIO board is bad. The diagnostics all passed. AlienwareFXTester reports no errors and says the Board is at 2.01.04. I find it hard to believe that when I'm taxing the GPU's and they reach temps of 70C that the fans never speed up or the ambient temps never get above 24C.
Has anyone seen this issue before? Is Thermal Controller or SpeedFan giving the correct temps? Or am I being paranoid about the GPU's being 70C?

The temps that ACC is reporting is just ambient case temps. There is a sensor near the CPU,GPU and front of the case that is sending info to ACC. That is why they don't move much if at all. SpeedFan is giving you the actual temps of the cores on the CPU and GPU. The cooling pump in the system is always at 100% so the CPU fan only kicks up if you are really pushing the system. Go run Prime95 and then you will see the fan pick up.
Now for the GPU the fans should be going up as it gets hotter. ACC has nothing to do with that. That is all done by the Nvidia driver and BIOS on the card. If you like you can go download MSI Afterburner or EVGA Precision and that will show to the fan speed and GPU temps and will also let you set the fans on Auto or Manual.

Thanks for the info. This is my first Alienware so wasn't sure if things were working right or not.
I took your advise and I'm now using afterburner to make the fans on the GPU's a bit more agressive.
