    Default Heat Problems

    I have a 6 month old system that is still under warrenty:

    P4 2.5 (512kb cache, 400FSB)
    P4s8x-x motherboard
    512 DDR PC333
    80G hard drive
    ATI 9200se 128MB

    underload temperature
    cpu:45-50C motherboard:27-30C room temperature: 20C

    full load temperature
    cpu:55-58C motherboard:31-33C room temperature:24C

    fan speed = 2500RPM

    At summer, my room temperature can reach 33C, and stay that way for 5 or 6 weeks.

    I am not such a computer expert so I am not so sure if I have a heat sink on my cpu or not. I opened up the case, but I am not sure what a heat sink looks like.

    I plan to use my system another 3-4 years.

    Is this temperature too hot?
    Will my cpu survive the 33C summer?
    Do I need to get a new cooling system?
    Do I need to lower my core speed?

    by the way, I am not a gamer, so speed is not really that important, I can live with 2.1 or 2.2

    the heatsink will be a large aluminium block with a fan atop it...

    I just went to my bios to check on the temperature. I stayed in the bios for about 15-20 minutes for the temperature to settle (underload).

    After the temperature settle, the cpu = 52C, motherboard = 30.5C, in a room temperature of 21.5C.

    is that temperature ok for underload?

    Not critical, but for a P4 2.5a, thats a little too high. Now, you could underclock the cpu, but that depends on if the board lets you adjust to a lower fsb in the bios. unless it has a pci\agp lock and lets you set memory speed independently, you'll also be underclocking the other components.

    Probably better to get a decent cooler (maybe a Zalman 7000AlCu), and some arctic silver 5 thermal compound. You'll need to remove any traces of thermal compound left on the cpu surface after removing the stock heatsink and fan, before installing another, although the equipment comes with instructions

    Since i am not a gamer, I don't really think I want to get another cooling system athough it is not that expansive anyway. I was wondering, I found the "Clockgen" program on http://www.cpuid.com/clockgen.php, do they work? I download one of them that supports my motherboard, but I am not sure how much I should under clock. Can any one please help me. I am not a expert.

    I ran that program, I clicked on "set values" then it told me my current clocks.

    CPU-2500.17
    FSB-100.01
    Memory-125.01
    AGP-166.68
    PCI-83.34

    How much should I underclock?
    And is this program safe to use?
    And can I change back to my original clock if I am not satisfied?

    You'll be fine with those temps. P4s have GREAT thermal protection, you could even pull your heat sink off while under full load and be OK, it'll just throttle itself back and run at a much slower clock.

    The AGP should be 66mhz and PCI 33mhz.. You sure that wasnt a typo?

    I am not so.

    My question is, can I use the program to underclock?
    because bios only let me to overclock, not underclock
