CPU Model: E6400 Stepping 6
CPU Clockspeed: 2.14GHz
CPU Voltage: 1.213 (CPU-Z)
Motherboard: Intel D975XBX Bad Axe
BIOS Version: 1334

I know many have discussed this, and I *HAVE* used the search function, but it seems it hasn't been definitively answered;
Specifically, the issue with Bad Axe reported CPU temps....


Using Intel's BIOS and utilities, and Core Temp, I get an idle temperature of the low to mid 40s and a load temp in the upper 50's; this is on stock. My system temps are also reported as 35C and 39C (two sensors).

This seems amazingly high considering that in the exact same case, with the exact same fans, I had an ABIT IC7-G Max II Advance with an overclocked and overvolted Pentium 4 Northwood; the system temp was reported as 29-33C, the CPU idle was 39-42C, and the load was 59-62C. This was using an old MCX heatsink that was inferior to the current AC Freezer 7 Pro I'm using.

In fact, I'd heard that the IC7-G reported temps a bit higher than they really were.

How can it be that a CPU running at a higher voltage and using an inferior heatsink have lower idle and load temps than this Core 2 Duo???
These temps *can't* be correct, can they?

[veryhumid]

bump?

[SupaMan]

its a little early for this, i think

[thunderstruck!]

I'd change the voltage reading to be reported by mobo software, dmm, or bios setting....basically anything besides cpu-z, since it's is never correct.

[veryhumid]

It's actually the same in bios as it is in cpu-z. at least at idle.

[Omarko]

bump bump ....

any temp readings anyone ?

[BlazingArrow]

well, my ASUS temps and Core Temp programs are about 20 degrees celsius apart....soooo ....which one should I report??

[Omarko]

I think we should all be using Core Temp, as aparently its the most accurate program we have that gives accurate readings ...

[Evilsizer]

well after dual prime95's for about 20mins the coretemp proggy read:


ambient temp around 70F
core1 54c
core2 53c

cant get the uguru software to work at all. no other program but coretemp works atm.

[mystupidmouth]

Isnt Core Temp just a Estimate?

[Omarko]

Core Temp reads directly of the digital diode on the core die so its VERY accurate.

Evil - those temps are about the same as mine when two cores under load ... 54-55C with intel stock HSF ....

I spoke ot another guy today with exactly same config as mine (p5W dh deluxe, e6400 and OCZ ram) and his temps are around 42C under load ... I was surprised and confused to see that.

funny part is im using a ninja with yateloon and rear case 120 denki @7v and at stock speeds.

Since all Intel cpu temps have been read from on-die thermal diodes since the P2, what makes Core Temp so much more accurate?

This is wrong. You are right that the capability to read on die has been there, but MOST mobo makers do not tap into this, and still dont. Also, the thermal monitor has been redone with the new core 2 chips which varied from the dual thermal diodes in P4's and before. The P5W DH STILL does not read on die.

If modern Intel mobos don't read the on-die cpu thermal diode(s), what do they read? I haven't seen an in-socket thermistor since I built my last AMD rig with a T-Bird 1200 and I've never seen one on an Intel mobo.

oh very nice that there's somebody else who uses the TT Blue Orb II.
I see that it fits on the P5B Deluxe, do you guess that it will also fit on the P5W DH Deluxe???
Because i'm tired of using watercooling, and for the fact that i also have to use some additional fans for the rest of the Mobo.

I can't see why not, though my orb dose extend 5mm past the top of the mobo, so you do require some clearence from the PSU.

The Blue Orb2 is under-rated, it performs within 1 ~ 2 deg C of the Big Typhoon, but is quieter, and dose a better job of cooling surounding components, mobo/northbridge/ram/display card. The only down side is it's not suitable for people who change ram modules more than there underware... which might apply to a few people around hear

Yeah, it just barely fits. There's less than a 1mm gap between the mosfet heatsink and the Orb. When it's fully tightened, I could just about slide a piece of paper between them

[qujck]

hehe yes its the same prob on my DFI N4 Ultra D, it seems to be very difficult changing the rams

i'll use the TT with an Allendale 6400, so its a good choice.

guys ... when your CPUs are on load for a while, lets say leave it priming for an hour or so, is the heatsink hot to touch ? at over 50C it should be ...

my Core duo shows 55C but when I touch the heatsink its not HOT at all, certainly not as hot as the block on my celeron D which runs at 51C , when touched, my fingers burn.
