Very strange temps E6600??

THEMIGHTYMAXTOR · 10 May 2008 at 09:43

Just swapped out my E6300 for a mates E6600 and in coretemp, the CPU temp is at idle 35c however the 2 core temps are at 50c!! I am running on a freezer 7 which is fitted correctly, whats wrong with these temps??

50c whilst idle is too high, my old E6600 used to idle at about 30c. Try reseating the heatsink and replacing the thermal compound.

THEMIGHTYMAXTOR · 10 May 2008 at 10:59

i have already and tried different heatsinks/compounds, the cpu temps are fine at 35c its just the core i am worried about

Do you know what temps it was running at in your mates computer? as it might just be your motherboard BIOS incorrectly reading the temperatures.

THEMIGHTYMAXTOR · 10 May 2008 at 11:08

yes it was idle at 35 cpu and 35 core on his so I am thinking it may be motherboard, but even so, why does it come up so high in coretemp (which i thought was the most accurate)

Taken from coretemp website:

The temperature readings are very accurate as the data is collected from a Digital Thermal Sensor (or DTS) which is located in each individual processing core, near the hottest part. This sensor is digital, which means it doesn't rely on an external circuit located on the motherboard to report temperature, its value is stored in a special register in the processor so any software can access and read it.

The other CPU temperature is taken by the motherboard from a thermal diode on the cpu near the cpu heatspreader. So coretemp is correct and the cores are 50c. Are you using the latest version of coretemp?

THEMIGHTYMAXTOR · 10 May 2008 at 18:41

yes was the latest version of core temp aswell?! i was looking forward to overclocking this thing and im barely looking good at stock, mabye its normal for the cores to be this high, my cpu temp is only 35c!

EVILCOSMOS · 10 May 2008 at 18:47

At the moment my E6400 is idling at:

CPU = 26c
Core 1 = 31c
Core 2 = 32c

and that's overclocked to 3.2Ghz

What's the airflow like in your case, what volts is the E6600 on and is the fan on the freezer 7 at full?

THEMIGHTYMAXTOR · 10 May 2008 at 18:54

the fan is not on full, airflow is great, my other E6300 was at 35c on cores so thats not the problem, im so confused its weird, i havent messed with voltages they are at 1.280v

EVILCOSMOS · 10 May 2008 at 19:23

hmmmm it's a strange one alright, you could try and download everest and also speedfan to see what they give for the cores temperatures.

They're the same then? The only other things I can think of is to try updating the motherboard BIOS and to check that C1E and EIST are enabled in the BIOS.

If that doesn't change anything you will just have to assume the core temperatures are wrong when using that motherboard. Could you try the cpu in your mates computer again just to double check?

THEMIGHTYMAXTOR · 10 May 2008 at 20:11

Cheers for all the help cosmos, what is C1E/EIST??

No problem.

C1E and EIST are part of the Intel speedstep which lowers the cpu voltage and multiplier when it is idle to conserve power (and lower temperature).

THEMIGHTYMAXTOR · 10 May 2008 at 20:19

ahh yes cause i had this on 1.6ghz and i was told to run at 2.4ghz i needed to disable these features, will this affect temps though?

EVILCOSMOS · 10 May 2008 at 20:24

When it is enable the voltage on my cpu drops by 0.15v from 1.35 to 1.2v when idling, so it should be lowering them a little.

ron3003 · 10 May 2008 at 22:41

I have an e6600 overclocked to 3.4ghz and it idles in the high forties. If yours is 50c at the stock speed of 2.4ghz you deffo need better airflow. Dont forget it's been exceptionally hot just recently so you wont be getting the temps your mate got before the weather warmed up.

THEMIGHTYMAXTOR · 11 May 2008 at 13:15

a very good point, my temps are fine i think as my room is always hot, im looking at the swiftech compact kits as i really wanted to hit 3ghz! cheers for the help all!

Aren't the c2d's rated for up to 85 degrees? As long as you don't get too close to 80 I wouldn't care.

This hot weather is a real killer at the moment though which ever way you look at it.
