    Re: A Tip for Cooling Your Case

    Wow

    Indeed impressive... I have my favourite laptop in my draw which is over heating.....but the air intake is on the base of the machine and moulded[gggrrrr] I am going to use your post as an experiment and see if I could raise it off the desk to see if i can increase air flow.

    It is an XP machine, is there any software out there that can measure heat of the CPU?

    In addition to cooling the system, you may wish to visit TomsHardware to see how you can also create a quiet environment.

    Enjoy...

    20C is pretty impressive.

    What was your rational for removing the front fan? What we've done here sometimes is to have a front fan sucking air in, and the power supply fan and big 120mm rear fan blowing out.

    Re: A Tip for Cooling Your Case

    I removed the front fan because the negative pressure caused by the two exhaust fans (theoretically) exceeds the ability of the front-mounted fan to pump air into the case. If my logic holds up, having a front fan would actually serve to impede airflow through the case since the blades and would provide more of an obstruction - an air dam type effect. I recall having read some time ago in an AMD-published document that their testing had shown an intake fan to be of negligible value overall. Also, on this case the on the lower edges of each side-panel are slotted, so there should be no problem with air being drawn in.

    Mark,

    That's an impressive improvement in cooling!

    I do join Jim H, in asking why the removal of the front intake fan?

    Re: A Tip for Cooling Your Case

    You answered Jim's question just as I posted mine.

    That's an interesting theory.
    How about going a little further and replacing the front fan again and measuring the difference with just the other three changes in place?

    How many "Dust Bunnies" did you remove?
    These will build up and keep a CPU real warm and toastie.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    Re: A Tip for Cooling Your Case

    I'm not sure if you had a similar setup to mine, but I've actually got my front and side fans blowing in and my two back fans sucking out. Unfortunately, my case doesn't have much room for airflow, but the concept is good!

    Of course, I'm running a P4 2.4 and it usually keeps below 40C, except for when the room gets hot during the summer.

    Re: A Tip for Cooling Your Case

    Not too many, the box was in a fairly dust free environment. Or so my internal inspection seemed to prove...

    Re: A Tip for Cooling Your Case

    Hmm. Interesting.

    I've also wondered if a front-low mounted fan would act like a vacum clener, and suck dust up into the computer. I hadn't thought about back pressure.

    A Tip for Cooling Your Case

    To illustrate the benefits of proper ventilation in a "white box" computer that is built using off the shelf parts, I present a real-life experience that might help someone down the road.

    I worked on a system that was showing all the tell-tale signs of overheating. Strange lockups, random shutdowns, delayed responsiveness in Windows... so I checked the BIOS readings and installed Motherboard Monitor 5 to check from within Windows. The computer was running within five degress Celsius of the maximum allowed according the the CPU spec. To help alleviate things, I changed three - wait, four - things inside the case:
    1. <LI>I used ties to pin the cables back so that there was an airway between the front air intake and the area around the CPU,
      <LI>I removed the intake fan from the front,
      <LI>I upgraded the exhaust fan (not the power supply, which had a bottom intake) on the case rear, and
      <LI>I moved the sound card out of the slot next to the GPU so that the video card could breathe.
    After starting the machine back up - as well as removing the accumulated dust - the new CPU operating temperature was [b]20

    Same one I used (sadly no longer in development): Motherboard Monitor 5. <img src=/S/meltdown.gif border=0 alt=meltdown width=15 height=15>

    Re: A Tip for Cooling Your Case

    Ok...so what do us non A+ techies do with our over heated boxes? <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15> PS: I opened up a malfunctioning toaster a while back to see if I could get it to toast my morning bread. After switching it back on, it went "Poof", with a little smoke and NEVER worked again!!! I hesitate to think what I can do with a PC.!!!

    Could I just put it next to the aircon which is set to 15 celcius? <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15> Alternatively, I will FedEx the box to you...if you dont mind! <img src=/S/thumbup.gif border=0 alt=thumbup width=15 height=15>
    Regards,
    Rudi
