E4300 Temperature Help

[markmc]

Posted before, but I didn't really understand what I was doing. I think I have the format down now. Temperatures seem high in TAT, but I have reapplied the thermal grease and reset the heat sink with little change. Please provide any input that you can. I'm curious as to if I can safely go on and increase the FSB. TAT says no, Speedfan says yes. FWIW, the HSF is not at all warm to the touch.

Results

Tcase (Speedfan 4.32) = 17c Idle, 44c Load
Tjunction Hottest Core Only (Speedfan 4.32) = 21c Idle, 61c Load
Tjunction Hottest Core Only (TAT) = 38c Idle, 46c Load

Variables

Ambient = 20c
Chipset = 965p
C2D = E4300
CPU Cooler= Tuniq Tower 120
Frequency = 2.7 GHz
Load = TAT @ 100% 10 minutes
Motherboard = Gigabyte 965P-DS3
Vcore = 1.3125

u seem ok to me in ur current speed 2.7ghz what thermal grease r u using?
dont pushit harder

jetfx, please read the Core 2 Duo Temperature Guide.

markmc, didn't you mean TAT 76c Load? Also, it's more than obvious that NO temps can be below Ambient, and SpeedFan shows a Delta of 40, spec is 25. In addition to offsets, I believe you have a concave Integrated Heat Spreader. Have you checked your E4300 for flatness?

Looks like I reversed them, should be:

What is the best way to check the flatness?

Using Arctic Ceramique, gave marginally better temps than the Tuniq grease

Well that makes all the difference. Your Delta's are now in spec, so Tjunction is simply offset by -15c, however, Tcase is uncertain. A Tuniq Tower at 1.3 Vcore should Idle very close to ambient, but no air cooled temps can be below ambient. If your computer is on the floor, it's possible the temp at that level is lower than the 20c ambient shown in your variables. Can you verify this?

Thanks,

The computer is at floor level, so it is reasonable to think it is 1-2 degrees cooler, but I can't provide an accurate reading. The ambient temp is from the thermostat, so it contains some level of error itself.

 

[CompuTronix]

Very well, then we'll go with your Tcase as is, since it's Load temp is comparatively accurate relative to Tjunction. SpeedFan Tjunction is simply offset by -15c, so use the "Offsets" section of the Guide to configure a +15c offset in SpeedFan to correct for this inaccuracy.

You should be able to increase your OC and Vcore until you TAT at 55c Tcase / 70c Tjunction, which will Orthos ~5c cooler. Also, configure your temperatures to "Show in Tray" the hottest core.

Hope this helps, and enjoy your rig!

Thanks, you have been very helpful

 

[CompuTronix]

You're very welcome. Were you able to configure the offsets in SpeedFan?

[markmc]

yes, thanks.


I'm thinking I'll leave it at 2.7 for now, doesn't seem like the small jump to 3.0 would be worth the extra heat.

 

[CompuTronix]

You may find that you're able to increase clock while maintaining the same Vcore. Increases in clock have a minimal effect on temps compared to Vcore. Each increase in Vcore of .05 volts will result in a corresponding increse of ~3c in temps. Remember that at no other time will your computer experience loads equal to TAT, so with a high end cooler like the Tuniq Tower, you still have plenty of OC ceiling available, since your present load temps are still comparatively quite cool.

Hope this helps,
