CPU fan reinstall, heat probs

  1. a short story, lazy readers can just scroll down and see the figures...
    recently moved my comp to another room and on the way there ofc bumbed the machine into a door frame. Next morning went to set it up on its new place and boom. it turned on for a few secs only. once almost got to windows...
    Found out the minor bumb had been strong enough to release some of my cpu fans attachment plugs and it wasn't connected to the processor anymore.
    So got some zalman thermal grease (ZM-STG1) and cleared the old paste off and applied the new thin layer(on the bottom of the cooler, a round part that touches the processor + a thin layer on the processor, shape of the cooler-part touching it).
    Everything back together, things looked fine.

    Thought id make sure and installed pc probe. Don't know much but according to teh internetz and some forums the temps were high.
    Installed other temp monitoring software (speedFan, core temp and Pc wiz 2008)
    all reported same high temps.
    After a day of struggling about, I took it apart, removed the paste, reapplied (an even thinner layer, only on the processor and all of it's surface area), and booted up.

    temps were even higher...
    (although i found a thin plastic film under my graphics card cooler unit, which said remove before use :D(it seems have lowered my GPU temp a touch)).

    im running out of solutions...
    Is my processor broken somehow? Could the temp measuring thing be broken?
    is it the fan that sucks? Did I mess the Thermal grease part? has my comp always been this hot. or am i just too paranoid about the temperatures...
    (The thing is, I have no idea what the temps were before this whole shebang)

    current temps according to speedfan:
    idle-busy (in celsius) [room temperature 20C]
    MB: 38-45
    CPU: 48-77
    core 1: 47-78
    core 2: 47-78
    GPU: 47-76

    CPU: 900- 2300rpm
    POWER: 1000-1100rpm

    System (factory settings)
    MB: Asus P5B
    Chipset: Intel P965
    Processor: Intel Core 2 Duo E6300 @ 1866 MHz
    Physical mem: 3gb
    graphics: Nvidia GeForce 7600 GT
    OS: XP Sp3

    this is what ive learned so far:
    cpu temp normally around 50C, bad if over 60C...
    is this correct?

    Every bit of help is very appreciated! I Feel really lost with this...

    The funny thing is that the cpu fan sink doesn't feel warm to the touch at all, not even when the temp is reportedly at 78C and the chassis feels really room temp.

    Design specs for the E6300;

    Core 2 Duo E6300
    (dual 1.86GHz - 2MB) 1.2V
    (0.85V~1.5V) 1.55V 75A 65W 61.4° C

    Thus, at 61.5 degrees it starts to throttle and if the temp runs higher faster it shuts down.

    I would suggest one leg of you heatsink is NOT attached.

    strangely it still doesn't hang up even at 78C :D

    I' ve checked that the heatsink is securely in place, it doesn't jiggle a bit.
    rechecking now... yup it is solid.
    I had a closer look when i reinstalled it the 1st time, and couldn't find any broken parts.
    Even checked the Motherboard holes where the plugs go in. looked unharmed.
    I had some worries about the fan condition too, but it seems very solid...

    Then SpeedFan is bonkers.

    What does your Bios say? Or Everest?

    Bios say approx the same idle temps. around 60C at 1st.
    For some reason I can only get to the bios temp check every other time without the whole comp freezing up, even then it takes a while.

    Ill try everest, but i have 4 programs now that all show the same numbers, more or less..
    PC Probe II, core temp, speedFan and PC wizard 2008

    [everest ] showed the same temps [/everest]

    If you have disabled CPU TM in Bios you won't throttle and could blow the CPU.

    The setting is under Advanced, CPU Configuration, 4th from the bottom.

    It's possible it already is shot.

    edit: what Bios version do you have? They had a temp algorithm fix in 509.

    CPU TM is set to enabled. has always been.

    my bios version is 0806 (10/26/2006)
    its american megatrends and its the one that came with the comp. haven't had any need to update yet.

    I hade a stock Intel heatsink that wouldn't 'jiggle' BUT one leg a piece of the spreadable plastic bent so it was 'kind of' attached BUT not making good contact.

    Outside of that, I have no further =ideas (have a severe head cold and am not totally here).

    Many thanks anyway.
    Ill have to look into getting a new cooling options.

    take care mate

    Fixed now. Fan was faulty, got a new bigger one.
    temps normalized.
