    Fans...do Epias really need one?

    I'm on the last stages of my build. I have a Epia 800, do I need a cooling fan? I have a couple of 80mm fans that I can use but not using them would save me some space. I'm running a full sized hd if it makes a difference.

    I added one just to be safe. I figured it was easier to add it while I was building my case, than to find out I need one later and to have to go back and put one in. I just did 1 80mm fan though.

    If noise concerns you, space permitting, use a 120mm undervolted.
    It will be quiet but still move a bit of air.

    I incorporated one in my case plan too, but not having it would allow me to fit the case in another spot. If all else fails I can always add the fan before the final install since it was the original plan.

    I put my Epia800 in a cardboard box (20cm x 30cm x 10cm) temporarily to see whether it works etc, and with the lid closed it would get extremely hot within 20 minutes of running a DVD. It didnt shut down, but it worried me enough to install a fan...

    Best way to tell is to run a temp monitoring program while putting it under load. MBMonitor is a good one, but there's many out there. I don't remember exactly what the heat ceiling was (you might want to look it up), but I think you're ok well into the 70's and maybe even 80's degree C (yes, those numbers should freak people who have overclocked out, but this is a very different problem space.)

    You're probably ok if you have adequate ventillation, but it never hurts to toss a small, low speed fan in there. Mario, an undervolted 120mm fan is good advice in general for quiet cooling, but is way overkill for an EPIA!

    In almost all cases, you're probably right. I only mentioned an undervolted 120mm simply because we do not know what size case he was running. Also, he said a standard drive and not stating whether it was a 7200RPM drive or not. That being said, I suggested the 120mm. Panasonic as well as others make low profile 120mm fans that could work quite nicely undervolted.

    Just my opinion though...

    I have a 120mm in and 80mm out. The 80mm makes no noise, but the 120mm at 12v is like a hurricane. At 7v its not so bad and at 5v can barley hear it. Boards not an itx, but it keeps everything just a degree or so above room temperature, even the CPU. I plan on making the 120mm voltage switchable thru relay control and making a program when the temperature high the fans kick in to +12v instead of +5v. Might even add a +7v.
    I say you might want to think about cooling when designing your system. You might as well tackle heat in design then having to rework everything.

    Check out 'panaflow' fans they are super quiet and come in all sizes.

    I even have an extra 80mm I'd be willing to part with for what I paid + shipping.

    I actually did design the case with one 8mm fan in mind and the ability to add 2 if needed (in/out flow). My case is roughly (I'm at work and don't have it here, but the specs are pretty close)...4" high, 11" long, 8" wide. It's made of plexiglass that's < 1/4" thick. I have slots/air holes in the case so it can breathe. My HD is a 40 gig 7200 rpm maxtor. I plan on running a USB hub with nothing attached to it at this time. Just a place to plug in a pen drive or my mp3 player when needed. I'll also be running a full sized dvd rom. The case is going to sit almost on the floor in a center console that I'm custom building right now.

    I'm thinking one 80mm fan should be sufficient right?
