    I could have sworn I saw a doc on how to get to it but I don't find it now... if one wanted to put AS6 on instead of whatever crap they use is it possible to reach the CPU without too much hassle?

    To get to the CPU you basically have to disassemble the entire laptop.

    You're better off getting a notebook cooler, as that operation you want to do for the arctic silver WILL VOID THE WARRANTY.

    Yeah I don't really want to go through that... just the replacement 1400 I got runs hotter than the previous one and I am trying to find alternatives to returning it...

    I don't want to go voiding warranties though...

    No. That is not true. To access the CPU, you just need to remove the heat sink. First, remove the L-shape cover on the bottom by the vent. Remove the 4 screws (start from #4). Take the heat sink out. Use a flat screw driver to rotate the processor release latch counterclockwise and lift the CPU out.
    Having said that, each CPU has its own ID and the unmatched ID may void your warranty. If your new system simply run hotter, try to add some thermo compound between the heatsink and the processor. Make sure you remove the old compound first to ensure good contact.

    I wasn't planning on swapping procs, just redoing the thermal paste...

    Problem is I am benching it and temps are running hotter across the board... to threadjack my own thread on my old one the cpu is running about 51/56 under bench and the new one is running 62/62...

    I am confused by the fact that the cores report differently and one is over 10C cooler... makes me wonder how that can even happen...

    Mem temp and GPU are both higher on the new one too by around 5C which I don't particularly like.

    Chipset was reading around 15C hotter yesterday than today and I can't figure out why at the moment...

    Once I get all my info together I will call up Dell and see what options they give me but I am not liking where I am just now...

    If one core is running cooler than the other it could be because only one of them is on. Power management may shut one off, and if you're looking at BIOS temps it may not use the second core at all.

    I am running a program called battery eater (it's designed to drain laptop batts) on both 1400s at the same time and I have a widget that shows core useage, it shows 100% for both cores so it's pushing both cores for sure...

    It seems odd that one laptop shows the exact same temp for both cores all the time and the other shows one as always cooler...

    I am not 100% sure this program is made to run on dual core machines but my feeling is that the cores both register 100% useage so that should mean it's in fact doing that.

    Temps are being taken with i8kfangui running on both machines.

    And they just finished battery testing and stupid me forgot to change power options but they both hybernated with about 10% left around 2hours and 10 min with the replacement (higher temps and more fan useage) dying about 10 minutes earlier.

    :(
