Core 2 Duo Temperature Readings

[dopee123]

I'm convinced those with high temps have a concave IHS or heatsink. Remove your heatsink and check the thermal paste distribution and see if theres is good contact in the middle. If not bust out the sandpaper and get to lapping or RMA like I did. I'm still waiting for my processor to come back from Intel. My comp pieces are just sitting in the living room collecting dust. Makes me pretty damn sad.

With my E6300 running at stock speeds and up to 450 FSB (vcore unchanged), Core temp and TAT showed both cores idling at 58C, loading one core brought it up to 77C and the mobo shutdown. This is with an Thermalright Ultra 120 too, and the drop of artic silver in the middle of the cpu method.

This "Thermal Specification" means nothing. What are they testing to get that temp? are they saying if you go above this temp that the chip will instantly become unstable, or if you are running it 24/7 for 10 years at this temp it won't last for another 10,...

Most are putting more volts than spec( 0.850V-1.3525V which is what it needs to "run properly.") and it seems to run fine. Generally specifications like this have a very large margin for error, part of it is usually built into how these things are calculated. Like I would think they need to think about those who will be running this hard for months on end, and are using the worst of the batches of cpus, in a genaric case without after market cooler. Or it may take into account that some time in the future after it has been running for a long time and doesn't run as well as it does new that it should still run given that it's under a certain temp. There are just so many things to consider when looking at these numbers that they really don't mean much. I would think unless you are unstable or have very high temps it shouldn't be a worry at all.

Define "very high temps". I think that's is the key issue here. A CPU running at 60C is "very high" imo. Esp. when the manufacturer says 61 is it's "rating", yeah whatever that means.

I'm currently stable at 3.36 ghz (1.25vcore) on a 6300 with a Big Typhoon. I idle at around 38 and at full orthos dual core load, I top out around 61C after an hour or so. I was a little worried I hadn't planted the heatsink on the arctic silver correctly (the heatsink is huge - hard to get big hands in case ), but it seems to be falling in line with others' experiences.

I might try to remove it and replant it again, just to see how variable it is.

I just replaced a Gigabyte DS3 mobo with an ASUS P5B dlx.
The idle temps on the ds3 for my e6600 where @ 28-30C, but with the p5b they are 38-40C. Stock speeds. no OC. I use the same HSF (zalman 9500) on both motherboards. I tried reseating the heatsink but not change.

I don't see how the same processor can run 10C hotter on a different motherboard. Is this possible?

thanks

ps. I was getting my temperature readings from the system BIOS.

Core Temp is buggered on some chips I believe. Here is why I believe this, while running phase I have tried out 4 processors. Each one has come up with a different number that is the minimum that the processor idles at on Core temp. One said 1 degree C for each core, Another said 8, Another 11, and Finally another 13. Each of these processors was running at between -25 to -8 at full load. I believe the Intel thermal diode is just poorly configured on some processors because it was never intended to be used. That is why some people say Core temp is 10 degrees high, when the processor bottoms at 8,11,13 which should be the bottom point of 0 it would scew all results.
