e4300 temperatures

[mrknowitall]

I run an e4300 with the stock cooler at 2.7GHz. I'll turn her up a bit (only running 667 memory) higher one day when I get a better cooler.

OK, I know the temps here are a bit high, but they were better yesterday before I turned my one and only case fan (120mm in a P150) down to low. It used to be on medium. I just learned I need to set it back to medium

Anyway, my concern is the relationship between all the temps. It seems lots of people seem think TATis reading their e4300 correctly, but it doesn't look that way for me. Please enlighten me:

\\\\\\

Ambient = 24
Chipset = Intel 965
Motherboard = Gigabyte DS3 Rev. 3.3
C2D = Model e4300
CPU Cooler = Stock Intel
Frequency = 2.8GHz
Load = TAT 100%
Vcore = Stock 1.325


\\\\\

Idle:

Core Temp 0.94
Core 0 35
Core 1 35

SpeedFan 4.32
Temp1 40
Temp2 27
Temp3 -2
Core0 35
Core1 35

TAT
CPU0 57-58
CPU1 54-55

\\\\\

TAT 100% Load

Core Temp 0.94
Core 0 67
Core 1 66

SpeedFan 4.32
Temp1 41
Temp2 60
Temp3 -2
Core0 67
Core1 66

TAT
CPU0 79-80
CPU1 79-80

Also, seems like the delta between Tcase and Tjunction is much smaller for me than most others. Weird? It's like everything in the temps guide doesn't apply to me 🙁

Thanks!

mrknowitall, complete information is required so I can analyze your temps. Please follow the format in the Core 2 Duo Temperature Guide:

...when expressing Idle & Load test results, it's also necessary to define the variables such as:

Tcase = Idle & Load
Tjunction = Idle & Load

Ambient = Room Temp
Chipset = Model
C2D = Model
CPU Cooler = Model
Frequency = CPU Clock
Load = Test Programs
Motherboard = Model
Vcore = CPU Voltage

Thanks,

I modified my original post with the requested information. Thanks guys.

 

[mrknowitall]

maybe my offsets are wrong?

 

[CompuTronix]

The term "Delta" refers to Idle versus Load temps. In your instance, Delta exceeds 25c, which is Intel's spec, and typically indicates an improperly seated stock CPU cooler, and / or a concave Integrated Heat Spreader.

To avoid confusion, Tcase versus Tjunction is refered to in the Guide as "difference". In your instance, Tcase appears to be correct, and Tjunction is correct in TAT, but is offset -15c in Core Temp and SpeedFan 4.32.

Check the fasteners on your CPU cooler and verify that all 4 are securely latched completely through the motherboard, then re-test. Use the "Offsets" section of the Guide to configure SpeedFan to correct for your Tjunction offsets.

Hope this helps,

OK, so th delta is too high and I will look into that tonight.

And you're saying the almost 80c Tjunction in TAT is correct...so I was basically right on the verge of throttling when I ran the test? :0

Regarding the 'difference'...Tcase is Temp2 in my Speedfan?

Thanks.

 

[CompuTronix]

Yes, exactly. You were on the edge of throttling, which is overtemp, and SpeedFan Temp2 is Tcase.

OK, so last night I pulled up the stock intel heatsink to figure out why my temps were so high. Looks like the stock compound distribuetd nicely, but I think I am going to try again tonight with some better compound if they have any at Fry's. And I made sure the san was seated properly and tight to the board. In the end my temp did drop a bit, but not much. I was still TATing in the high 70s at 2.8GHz.

My question, though. Can Tcase and Tjunction be different? Because the difference between mine if only like 7 or 8 degrees. So to get Tjunction in Speedfan to agree with TAT and Tcase to be 15-deg lower (which is a PARAMETER, correct) I would have define independant offset for the two temperatures.

 

[mrknowitall]

OK, Comp, how about taking another look. Since my last post I have installed a new SATA drive and removed the stock intel cooler and replaced it with a Ninja RevB / 1400 RPM Yate Loon fan.

I present results at stock 200 mhz fsb, 300 mhz, and 333 mhz. Please let me know what you think.

Results are presented as:

TAT: Highest Core Temp (Core 0 usually 2-3 degrees higher than Core1)
Speedfan: Temp1/Temp2/Temp3/Core0/Core1
CoreTemp: Tjunction/Highest Core (though the cores are the same - or only 1 degree apart)

OK, I just realized that I made all those measurements with the clock-adjusting setting on in my BIOS. So it was idling at 6x instead of 9x. So my idle temps are actually a degree or two higher than what I listed.

It just seems like my temps are too high. I'm considering lapping my CPU. Does anybody have any thoughts on that? Or some good links on the topic? Almost everything I read is about lapping the heatsink, but I have a feeling it's the CPU...thoughts?

There can't be any Idle temps below ambient on an air cooled system, so SpeedFan Tcase is still offset, and SpeedFan Tjunction is offset by -15c, but since your Delta of 35 is so far out, (spec = 25), then lapping or RMA is necessary. Check the Overclocking / Cooler and Heatsinks section of the Forum for info on lapping.

Hope this helps,
