Help me get to the bottom of this temp issue (c2d)

mobo reads from CPU socket, and generally aren't properly calibrated.


Im getting poor temps from my TT120 aswell. E6600 @ 3.535Ghz at 1.51V = 56C Orthos load :confused: Gaming/folding/video stuff only hits 50 :confused:

Stable so its ok :D

1.6v is quite a lot of voltage, remember this is over 2 cores..
Seeing similar (ish) temps at 3.9ghz and 1.6v on water here tbh, so they dont seem that far off.
The CPU's do kick out quite a bit of heat once you up the voltages and clockspeeds, similar to the AMD X2 series, once you bung above say 1.45v into the chips temps start to rocket.
I'd be less worried about your temps than the poster of this thread about his.

Good to know im not the only one

Me..same issue:confused:

When I built this system at stcok speed and volts memps were quite low for air cooling...mid 20's idle and about 40 full load..that was using Gigabyte's easytune5.
I overclcoked and have got a stable system at 3.5Ghz with 1.4V on the CPU in BIOS. Easytune reads a CPU voltage of 1.38. Im using a Scythe Ninja rev B.
My temps idle using Intel TAT are mid 40's and when full loading on both cores using Orthos hits about 70C. Ive tried reseating the cooler many times and have even hacked a bit of the mounting bracket cos I though it was resting against some motherboard capacitors (using a DS4)....still no change in temps.
I bought my CPU from here just under 2 weeks ago from here...do you think we have got a bad batch that dont seem to control the temps very well...albeit very stable at 3.5Ghz. :confused: :confused:

Also why does the motherboard monitor software read a lot less on the temps?? up to 10degrees less?

The temp sensors on boards have always been crap. Abit nf2 boards use to be nearly 20 degrees too high but everyone knew this so wasnt too bad
 
Have you tried this chip on another board [ui]ICEMAN?

As Its_Me says, Coretemp reads it direct from the CPU so the board type will have no impact on the reading.

Some people at xtremesystems say keep under 75 for stability. This is more than id like but does show how little the heat affects these chips compared to the opteron dual cores. I remember on my 170 when if i upped the voltage 1 notch it would fail prime due to the extra couple of degrees - 45 degrees was the general cut off point between stability and not
 
so what are you getting at...if you have a decent overclcok and a stable system with temperatures that arent toooo high then thats is good to go...dont worry about it until you get some instability!

Im happy with that...but I would still like to know (along with Iceman) why some people are running OC'd to these speeds with similar or higher voltages and getting far lower temps. Anyhow...I think my CPU/System will go fatser...its just that I dont want to give it any more power now. Its maybe worth buying and selling just to try another CPU.
 
So are people suggesting here that the temp from coretemp is read directly from the on-die temp sensor? i.e no post processing etc so the temp is pretty much always spot on?

Yes, read the links i posted - it explains it fully.
 
My temps as stated in the original post have always been from CT and TAT :( Temps are around 60c load now with 1.3v vfsb, 1.335 vcore @ 3.4ghz, guess this will have to do till my QX arrives later this week.
 
If at stock, using the stock cooler (fitted properly) you're CPU exceeds the max safe temperature for the chip (not sure what it is to be honest) then you have grounds for RMA.

Absolute max is listed as 85.

Its also important to understand that the C2D has 3 sensors on the chip, the 2 that TAT and coretemp read from are digital embeded within the CPU die at the hotest point.
 
A quick check of the Core2Duo spec says for a E6600 the max temp should not exceed 60.1C.

So If I stick the stock cooler on it and put it at stock volts and the full load temp is higher than 60.1C full load using Intel TAT...then I have grounds to RMA the chip back to Intel and get another??

no,

you must prove that the air inlet temp for the Intel HSF is less then 39.5 deg C, and also that it exceeds 85c under full load.
 
I think a big problem with the core duos is the top of the cpu isn't flat.. on my extreme, I can put a razor blade across it and you can plainly see that its not perfectly flat.. This coupled with the fact that at 1.55v im getting top temps of 65 degrees on water.... at stock voltage the load temps are around 40-45 however the voltage really does add extra heat to these.. I'd say that if you want low temps and good overclocks you need to be lapping..
