E6600 OC 3.4GHZ - Normal Temps?

Last response: in Overclocking

I have my E6600 OC'd to 3.4ghz. Speedfan is giving me these temps at idle, has flames next to temps. Just curious if these are acceptable temps? At stock it runs 41-45 celsius on average. System is air cooled, and I have a Zalman fan on CPU.

CPU- 54 Celsius
Core 0 - 51 C
Core 1 - 47-50 C

Before you post questions, please ^look^up^ and read the Sticky's at the top of the Forums, such as the following:
Core 2 Quad and Duo Temperature Guide -

Your answers are in the Guide. Also, you haven't provided nearly enough information, however, at a glance, your temperatures are obviously not calibrated, because CPU temperature (Tcase) can not be higher than Core temperatures (Tjunction).

From the Guide:

Section 2: Specifications

Since temperatures can be confusing to decipher and compare, it is very important to be specific, so when listing Idle & Load test Results, it is also necessary to list the Variables as shown below:


Tcase = Idle & Load ???
Tjunction = Idle & Load ???


Ambient = Room Temp ???
Chipset = Model ???
C2Q / C2D = E6600
CPU Cooler = Zalman Model ???
Frequency = 3.4
Load = Test Software ???
Motherboard = Model ???
Stepping = B2
Vcore = CPU Voltage ???

Section 4: Thermal Flow

  • Tjunction is higher than Tcase.

  • Tcase is higher than Ambient.

    Section 6: Scale

    Scale 5: Duo
    E6x00: Tcase Max 61c, Stepping L2, TDP 65W, Idle 12W
    E4x00: Tcase Max 61c, Stepping L2, TDP 65W, Idle 12W
    E21x0: Tcase Max 61c, Stepping L2, TDP 65W, Idle 8W
    X6800: Tcase Max 60c, Stepping B2, TDP 75W, Idle 24W
    E6x00: Tcase Max 60c, Stepping B2, TDP 65W, Idle 24W (Spec# SL9S)<--E6600
    E6x00: Tcase Max 60c, Stepping B2, TDP 65W, Idle 12W (Spec# SL9Z)<--E6600
    E6x20: Tcase Max 60c, Stepping B2, TDP 65W, Idle 12W

    --60--/--65--65-- Hot
    --55--/--60--60-- Warm
    --50--/--55--55-- Safe
    --25--/--30--30-- Cool

    Section 8: Tools

    Note 2: SpeedFan - Very flexible and configurable, SpeedFan is the preferred temperature monitoring utility because Tcase and Tjunction can be Calibrated. SpeedFan detects and labels thermal sensors according to various motherboard, chipset and super I/O chip configurations, so the label for Tcase can be CPU, Temp 1, Temp 2, or Temp 3. Even if Tcase is labeled as CPU, it is still necessary to confirm the identity of Tcase prior to performing Calibrations.

  • Repeatedly start and stop Prime95 Small FFT's at 15 second intervals, while observing which SpeedFan temperature scales with an Idle to Load Delta similar to the Cores. This will identify the label corresponding to Tcase. Labels can later be renamed using the Configure button. See Section 11.

    If a temperature shows a flame icon, this indicates alarm limits which require adjustment. Use the Configure button to set CPU and Core temp alarms to Warm Scale. If a temperature shows Aux 127, this is simply an unassigned input which can be disabled using the Configure button. See Section 11.

    The Guide can be used to learn how to properly test, calibrate and monitor CPU termperature and Core temperatures.

    Hope this helps,

    I've followed the directions for Speedtest/Primer95 and CPU/Core0/Core1 are the only temps that change when I start a stress test. What would I need to do to get the correct temperature for the cpu?

    I think I understand how to set the alarms according to the guide, but I'm still lost as to which is "Tcase"

    Section 8 in the Guide explains how to identify which temperature is "CPU" and Section 11 has more detailed instructions, as well as a link to SpeedFan's homepage. SpeedFan is a somewhat advanced monitoring utility, so if you find that it's a bit much for you, then perhaps you should instead just download and run RealTemp -
