    I'm new here, and some of you may have seen this in the
    alt.comp.hardware.overclocking forum, but I thought I'd post it here as
    well since it is an ABIT MB.

    So first let me say hello and thanks in advance to all who spare a moment
    to provide their thoughts.

    I have an ABIT IS7 motherboard with a P4 3GHz/1MB overclocked and stable
    at 267Mhz. So my 3GHz CPU is running at 4.005GHz. I'm using the stock
    heat sink and fan on the CPU. I'm running Windows XP Home Edition. I have
    the following settings and temperatures at idle and at load while running
    Prime95 v2.38 at maximum torture settings:

    Bus setting: 267/66/33
    Memory: 5:4 (512x2 DDR PC3200 @ 214MHz) someday I'll get PC4000 & try 1:1
    AGP Setting: Fixed 66/33
    VCore: 1.5875v (Prime95 produces errors at voltages below 1.56v)
    DDRcc: 2.70v
    +3.3: 3.3v

    Temperature at idle:

    Sys: 31c | CPU: 54.5 +/- 5c | PWM: 50.0 +/- 5c

    Temperature at load (Prime95 maximum torture setting):

    Sys: 35c | CPU: 72.5 +/- 5c | PWM: 71.5 +/- 5c (getting hot here)

    The system is rock solid at these settings and Prime95 ran error free for
    two hours. No crashes. No I/O problems with Sondra2005 disk drive test.

    Any suggestions on a better CPU and PWM heatsink fan combo that will fit
    on this MB inside by Antec SLK1600 case (300watt stock power supply was
    upgraded to 450watts, hey what can I say, the case was free).

    -------------------

    Here's the ThrottleWatch data @ 4.005GHz. The first throttled data point
    was at CPU temp of 68c. No throlling seemed to occur until that temp. Max
    temp was 72.5C +/-5C on CPU and 71.5C +/-5C on PWM; temp fluctuates up
    and down quite a bit on the ABIT EQ monitoring app, but never exceeded ~
    77C.
