    Whatever CPU you buy has certain "Stock" settings which are what the cpu was rated to use. When you overclock you are making your cpu go faster than rated so therefore the lifetime based on stock speeds will decrease according to the overclock.

    So basically this last day or two id say my computer was on for 15 hours. Most of those hours were while the cpu was overclocked so instead of my cpu decreasing in 15 hours of its life expectancy would it be reasonable to say it really lost 20 hours instead due to the amount of time it was overclocked?
    Even if that eventually happens, as long as you keep your OC settings reasonable your CPU will most likely be obsolete by then. As long as you don't go crazy with Intel Burn Test or similar tools.

    My dad is still using a Pentium 4 2.8ghz with 768mb ram and a 6800XT AGP so until my computer gets to that point I don't think I really have to worry about much. Besides I DO plan to overclock when 2.66ghz doesn't cut it anymore but that will probably be a LONG time because a lot of games still work fine with a single core and I have 4 of them plus hyper threading.

    The Intel 68C Thermal Specification for a Core i7 920 is measured at the geometric center of the heat spreader after drilling a hole into your CPU and mounting a thermocouple. This isn't very practical for the average user which is why Intel mounts sensors on the hottest point of each core. Core temperatures are what programs like RealTemp and Core Temp read and the data from those sensors is what ultimately controls when the CPU will start to thermal throttle or slow down.

    When running high stress programs like Prime 95 or Linpack, the peak core temperature can be a good 25C to 30C hotter than the Tcase temperature measured at the center of the heat spreader.

    Most Core i7 CPUs will not start to thermal throttle itself and slow down until the core temperature reaches 99C or 100C. The whole point of this is that even during the most extreme conditions, your CPU will still be able to run within spec and should rarely if ever reach the thermal throttling level.

    If it does happen to briefly reach the thermal throttling temperature, that's not the end of the world. Intel designed these things so when that happens, the multiplier will cycle between 21 and 12 which helps keep the heat under control. I haven't tested a Core i7 yet but I ran Prime 95 on my E8400 with the fan disconnected just to see what would happen. Three hours later, Prime Small FFTs was still happily running and only one core hit 100C and that was only for 1 second. Most of the time the core temperature sat at 98C and the CPU never skipped a beat.

    If Intel thought that running one of their chips at these extreme temperatures was going to damage it or reduce its life span then they would lower the thermal throttling point but they haven't. The whole reason why Intel went to on chip sensors when they developed the original Core processors is so that users could reliably get all of the performance out of their CPUs without the chip prematurely thermal throttling and slowing itself down due to inaccurate, approximated, Tcase temperatures.

    The short version. Intel makes great processors that do an incredible job of taking care of themselves. Stop worrying. CPUs will let you know when you are trying to push them too hard because they will lose stability. If you are stable and not thermal throttling then there is no need to be concerned about your core temperature. The OK word in the Thermal Status area of RealTemp means just that, everything is OK.

    Excessive voltage can kill a CPU so only use what you need. When overclocking, look at other things that might be holding you back before adding any additional core voltage.

    Im no expert, but even if you use higher than spec'd voltages but your cpu is running below spec'd temps, it should live a long healthy life . It would basically become obsolete before it dies as another poster said above.

    Then again, i dont really see the i7 becoming "obsolete" for a very long time.

    lol I see we are no longer posting our i7 temps here . I think i have found my 24/7s and should have this up tonite. I will post them in progression from when i started tweakin to where i ended up at.

    Come on everyone, throw some screens up for our viewing pleasure.

    One thing i really noticed was even with the AC on full blast when it was 90f outside ,temps were well above everyone elses.

    Now, on days when its 70 , my temps are more of what i was expecting and at nite it only gets better. We'll take a look later on.

    Thanks to everyone who took the time to bother with my posts. Everything i learned i learned from Tweaktown and LSD. Well not LSD LSD, LSDMEASAP hehe

    Truly appreciate it everyone.

    Ussing OCCT under 100% load I am getting temps just at or below 80c. average around 76,78. Idle is about low 50's. This is overclocked to 4ghz, is this too hot?

    Voltage is more of a concern than temps. I wouldn't want those temps all the time but let's face it full OCCT load is far from normal. Low 50's on the other hand is never going to hurt anything.

    I have an I7 920 running on a stock HS/Fan you can use for comparison

    Vcore @ 1.232 (cpu-z)
    QPI/VTT @ 1.200
    Dramm @ 1.580
    BLCK @ 170 x 21 (turbo on) = 3.57mhz
    Room temp = 22c
    idle temp = 48c-50c
    running LinX max mem 20 passes ... real temp shows 85c + and climbing

    After disabling cpu multi threading I dropped my vcore down to 1.23v, stable at 100% load. And now my temps barely hit 70c
