I5-750 on an MSI P55-GD65 MB - weird temps

[sjfphoto]

I'm running the 750 on an MSI P55-GD65. I have the CPU at (160Mhz x 20) 3.2Ghz. I'm running all default voltage setting with XMP enabled to auto profile. I'm using a ZeroTherm Core 92 cooler with Arctic Silver 5. I went across the CPU horizontally with the AS-5 as per the web instructions. My temps are significantly lower than with the Stock cooler. The weird thing is that at idle my temps are as follows:

Cores #0 and #2 are the same while Cores #1 and #3 are the same. Core #0 is using 3% CPU so I guess that makes the 1 degree difference. I find it strange that the temps seem to match in odd pairs. Any thoughts?

Do you think I could try to go higher on the overclock based on the temps I'm getting now?

Thanks,
Steve

Idle temps aren't that important. Load temps are. As far as the temperature pattern is concerned, I do not see anything significant. It's probably just random variations in the temp sensors that happened to line up that way.

Your idle temps are way too high! FYI, the idle core temps of my i5-750@3.6GHz are 27C-24C-26C-23C.

You will be fine as long as ALL core temps are within 72.7C which is the thermal spec from Intel.

Variations of 3ºC between cores is very commun. It's ok. Don't worry.
You can go higher on the overclock. Anyway, "Core temp" is there to control the temperatures.
Don't forget that the Tcase Max (CPU temperature) for this cpu is 78°C, the Vcore Max is 1.4v and the Tjunction (Core temperature, the Core temp ones) is 72,7ºC.

uuffff MSI whyyyyyy

all temps look fine for a stock cooler in a medium sized case - aok

Andy,

What MB are you using? What CPU Cooler are you using? What are your voltage and CPU settings in the BIOS?

I'm using the ZeroTherm Core 92 cooler with Arctic Silver 5. I have theAntec P-180 case. Very quiet; I thought very cool. The back case fan is currently off - I have to replace it.

I have my Vcore at 1.2188 v
VTT at 1.141 v
CPU PLL at 1.800 v
PCH 1.101 v
DRAM stock at 1.65 v
