Yea, it's a shame a lot of people just don't read the stickies. Though, the search feature leaves a lot to be desired at the same time.

Lots of good info. Well updated

Been a while since I had read OP. I like this Intel quote.

Quote:
Moreover, if a device is subjected to these conditions for any length of time then, when returned to conditions within the functional operating condition limits, it will either not function, or its reliability will be severely degraded.

Great guide, thnx for this info!
So I recently downloaded a bunch of cpu monitoring apps, so I could see which one was most accurate. Now I like HWmonitor, and speedfan the most because it gives me my overall CPU temps, along with the individual core temps, whereas the others just give the individual core temps. All the others such as realtemp, and coretemp, had my TJmax nativley set correctly.
My question here is that you said TJmax was inaccurate when idle, and my computer is idle more times than not, so how can I accurately monitor my idle temps??

The best thing to do is to not worry about the idle temperature since the idle temperature is very inaccurate anyway. But if the idle temperature were like in the mid 40's to the 50's, then it is good to be concerned. Otherwise, all that is important is what the load temperature is.

Something to note is that most of these programs are using a formula to calculate the CPU IHS temp and that is not a real reading.

I would add that if your CPU is reporting idle temps in the 40's and 50's, but the load temperature is not much higher say high 50's low 60's (small DeltaT), then it's still fine.

If you really want to know what your true idle core temps are, then drill a hole into your Integrated Heat Spreader (IHS) and put a J-type thermal couple onto the core itself. Since this isn't very practical, I would just accept that idle temps are not really that important as the CPU is designed to run at consistently high temperatures.

Have any of you guys noticed how HWMonitor seems to report very strange core temperatures compared to most other commonly used applications (core temp/real temp) when using i7? Check this out: http://www.xtremesystems.org/forums/...79044&page=155 (scroll down to post #3864 and read from there)

It's not so much that TJmax is inaccurate at idle. As it is the distance measured from TJmax gets more inacccurate the further away from TJmax you go.

I always thought the slight differences I saw in HWMonitor were do to the fact that it obviously doesn't update with newer readings at the same times as RT and CT do. RT and CT seem to update in tune with each other. HWM marches to the beat of its own drummer.
