OC e4300 Temps

[FloJa]

Hi all

Just wondering if this is right? I changed the offset on Core0 and Core1 on Speedfan up by 11. So they now sit roughly 15c higher than CPU (Tcase). Is that right? Do I ignore TAT now? Is that incorrect? I am running vista prem as well.


Tcase = 26 & 53 (Speed Fan 4.32)
Tjunction = 42 & 67 (Speed Fan 4.32), 52 & 71 (TAT)

Ambient = 20 Guestimite
Chipset = P965
C2D = e4300
CPU Cooler = Zalman 7700
Frequency = 333*9 = 3000
Load = TAT
Motherboard = Gigabyte P965 S3
Vcore = 1.424

Thanks heaps

Keep in mind that your Tjunction offset correction should agree very closely with TAT:

Interpretation

** The second part of the spec...Since Intel's Thermal Analysis Tool (TAT) is a Notebook tool, and desktop C2D's have an integrated heat spreader, TAT will typically indicate ~ 2c lower than SpeedFan 4.32.

Tjunction offsets are typically 15, which should apply in your instance as well, and not 11. Offsets of other values such as 5, 10 or 20 may be appropriate under certain situations.

Your Vcore is increased beyond the capability of the Zalman 7700 to cool even fairly well, so under the circumstances, Tcase idle is too low. If you increase Tcase offset by +5c and Tjuntion by an additional +4c, (total Tjunction +15c), then the following corrected temps are justified for your system:

Tcase = 31 & 58 (Speed Fan 4.32)
Tjunction = 47 & 72 (Speed Fan 4.32), 52 & 71 (TAT)

As you can now see, Tcase + ~15c = Tjuntion still applies, and TAT Load ~2c less than SpeedFan Tjunction Load also applies. These temps make sense, as they're appropriate for your Ambient, Vcore and CPU cooler.

Hope this helps,

Thanks comp,

changed all that. All looks good.

Thanks

You're very welcome! At some point in the future, you may prefer to upgrade your CPU cooler, since your temps are close to max'd out at low ambient, but for now, enjoy your rig.
