Alienware thermal controller reports 27 C while Speedfan reports around 35 C. ATC does not report the correct temp.

Where did you get Speedfan?

Thanks,

Yeah, he said it gives a little bit higher temps (idle was 32C for the 4 quads). Fan speeds were also a little higher. I'm amazed that the Alienware Thermal software doesn't  work considering how long it has been around.

Thanks,

Hi Harvey,

In a carpeted room with 20 cm clearance behind the PC my CPU temp reads ~ 28degrees.

Is that from the Alienware software? That's what mine reads and the question is whether or not it's correct.

It works but it is showing ambient case temps not the cpu temps.

I downloaded Speedfan to see what it was doing. I didnt play with it much, just let it detect sensors.  What I saw on my machine Aurora ALX was that it detected sensors for:

• 4 cores. Speedfan calls them core0,core1, core2, core3 and reports them as Chip = INTEL CORE, Bus = ISA
• 4 hard drives. Speedfan called them HD0, HD1, HD2, HD3 and reports them as Chip = HD0, HD1, etc, Bus = ADVSmart
• 3 other sensors. Speedfan calls them temp1, temp2, temp3 and reports them as Chip = F71882F, Bus = ISA
• It didnt detect GPU temp sensor for me (HD6870)

SpeedFan's HDD and Core temps report the right temps. I had RealTemp running at the same time to verify the Core temps, and I ran Prime95 to heat it up to verify they were in step with RealTemp.

The other three sensors (temp1, temp2, temp3) however were not so straightforward.

In Alienware Thermal Controls, all three of my ambient temperatures when testing were at 20C. My ambient temps rarely change no matter how hard I am hitting the system either CPU or GPU - but they do change based on room temp so i know they work.

Anyway, Alienware CCC Ambient temps initially matched SpeedFan's Temp1 as both were at 20C at idle, however the other reported Temp2 = 38C and Temp3 = 41 so those two did not match the Alienware Ambient temp sensor temps of 20C.

When I ran Prime95, Speedfan's Temp1 sensor immediately shot up to 46C, so that sensor is certainly related to CPU temp in some way, even though it didnt match any of the CPU Core temps at the time because those were all in the mid to high 50's.

I ran FurMark to heat up the GPU, and while the GPU temp sensor went from 53C to 65C pretty quick, none of the SpeedFan temps moved more than a degree, so none of them were the GPU temp sensor.

In summary, although SpeedFan detected three ambiguously-named temperature sensors in my AuroraALX, none of them reported the same temps as ATC during testing, so I am not sure what those temp sensors are ? I suspect Speedfan is actually detecting the Alienware ambient sensors, but is misreporting the temperatures.

hgratt, joealc, and realbrush - Alienware Thermal Control (ATC) Ambient sensors are reporting temperatures of the various system fans (system, PCI, HDD) and NOT cpu temperatures. So when running CPU or GPU intensive programs like games or SuperPI or Prime95, you probably wont see the ATC temperatures change very much at all perhaps only a degree or two perhaps more on the PCI temp sensor if you have 2 GPU cards.
