609703 2007-11-09 01:21:00 Hey -

Yet another question about my new set up!!

When I check the BIOS and the Asus tools for my P5K Premium - they are both saying that the CPU temperature is 7 ~ 10°C (have seen it drop to 2° at one point).

What controls the temperature readings for the motherboard?

I'm using a Duo Core 2 - E6850 and a Asus Silent Knight II CPU cooler (with ALOT of termal paste on it).

I mean I'll be stoaked if this is the real temperature but some how I don't believe it ...

609704 2007-11-09 01:24:00 I would doubt that something that generates heat would have a temp lower than room temp. DeSade (984)
609705 2007-11-09 01:31:00 There have been several reports / Questions regarding the Duo Core 2 temp in these forums latley, single digit figures are common.

The Duo Core 2 do run a LOT cooler than the older CPU's.
I you think about it, the CPU runs cooler anyway and you have a fan blowing cool air on the CPU all the time, thats basically doing Nothing when idle - so it is going to get cooler than air temp.

609706 2007-11-09 01:43:00 Have just been reading some information on TomsHardware - thinking of running Prime 95's "torture test" on the CPU to see if I can get the temp up?

So - for now - I can assume that the temp reading is correct?

The motherboard temp seems to be fine - stable between 20 ~ 25°C which is believable and the ambiant case temp sits around 28°, so I know these are right.

609707 2007-11-09 01:50:00 So, you don't want your CPU's temperature to be low? I guess you'd be the only one. Get SIW by Gabriel Topola and see what that says about the temperatures throughout your system. beeswax34 (63)
609708 2007-11-09 01:59:00 the last time I looked into a reported temp issue it was on an AMD Barton CPU.
The sensing diode was read by a Winbond chip then the value was modified by an offset to make it sensible before the BIOS displayed it. The offset figure was changed several times in different BIOS updates. Something similar could be happening here except that nobody has decided what the offset should be.

You'd need a lot of airflow to get lower than ambient temps.

"with ALOT of termal paste on it" usually is a recipe for disaster.

609710 2007-11-09 02:20:00 The thermal paste just needs to be enough to fill any small gaps, a thicker layer doesn't help. You are transferring heat from the CPU to the heat sink any excess in the middle is an interruption. PaulD (232)
609711 2007-11-09 04:44:00 My E6750 at default 2.66GHz was 9 degrees idle in winter. In hot weather, idle temps are around 15 degrees. Load temps never exceed 48.

Now at 3.2GHz, idle temps are around 20-25, and load 45-50.

Since I updated to my P5K's latest BIOS (which supposedly fixes C2D temp interpretation), the temperatures seem to remain about the same.

609712 2007-11-09 05:04:00 If the room is at (say) 20 degrees how could the CPU possibly be as low as 2!

It can't really be below room temperature, because the air being blowing through the fan is at room temperature. "Cool air" just feels cool, but is really no cooler than room temperature unless air conditioning is involved.

Of course if you live in Dunedin and these temps happen on horrible sub-zero nights, then maybe it's correct...
