E6600 Temp Verification

Hi all,

I recently put together a rig featuring an EVGA 680i (A1) motherboard, an E6600 Core 2 Duo processor, a Tuniq Tower, and 2 8800 GTX graphic cards. The case is a Silverstone TJ-09 with two TriCool fans mounted on the top (in exhaust.) The fan nearest the heatsink is set on low, while the fan over the RAM is on medium. Nothing is overclocked yet. Ambient air temp varies between 19-21C.

On boot, the CMOS often reads the processor at 33-35 idle, which I suppose is average but not great. In Vista (x64 edition,) Core Temp reads a much more pleasing 23-25c (averaged between cores.) I use Vista x64 because I have four gigs of RAM, but as a result, I can't run TAT. I was wondering which reading (CMOS or CoreTemp) is more accurate, and if there is another reliable temperature gauge that works with Vista x64, so I can verify the CoreTemp reading.

Thanks,

Mark.

CoreTemp or SpeedFan v.4.32 report the correct core temperature of the Core2Duo.

Ignore the temperatures reported by anything else.

I don't agree. Coretemp doesn't seem to give accurate temps for my E6600 ( see my sig. also) at all.

It would be very normal to assume that the people who fabricated my Mobo P5B-DL, Asus, know how to make the right Bios and software to read those temps...wouldn't it?

PC Probe is such software from Asus which is in the extra Asus P5B-DL package on the MB CD.

The temp in the Bios "Asus Monitor" is higher than in Windows with Asus Probe II but that's explainable cause in the BIOS the CPU runs constantly 100% like in the DOS mode. The MB temp is exactly the same;

In fact the Temps in Coretemp are too far off the chart unless you assume that Asus is not able to read it's own temp!??

BIOS Hardwaremonitor:
CPU Temp 35 Celsius
MB Temp 37 Celsius

In Windows with Asus Probe II
CPU Temp 24 Celsius
MB Temp 37 Celsius

Coretemp:
CPU Core 1 Temp 32 Celsius
CPU Core 2 Temp 32 Celsius
(Normaly the Core temps should be a little bit diffirent like 1 or 2 Celsius but thats a minor question)
 
Hmm...

It seems that the question as to which program gives the most accurate reading is quite dependent on individual specs: i.e. motherboard, processor, etc...

I wasn't aware that the bios temp is read while the processor is under 100% load. Is this is true for all motherboards? If so, that explains why the idle temp in CoreTemp (on my machine) is about 10 degrees cooler. Also, I read that the bios reads the surface temperature of the chip, while CoreTemp reads the internal temp. Anyway, if a 10 degree difference between the bios temp and the OS read temp is to be expected, then I'd imagine CoreTemp on my machine is pretty accurate. I will try Speedfan when I get home from work.
