    People will think you are mad.

    Why on earth do you need that much cooling?

    in an effort to reduce the internal temps of my computer case to below 33c
    it is now with 5 fans runnig.....i am considering using a tumble dryer
    flexable tube to atach to the back of the case so that the fan draws air
    directly from outside the house to cool it down. anyone see any probs with

    Hmm...might be a risk that the outside air is moisture-laden?
    Ok when it's not foggy or raining I suppose ;)
    Don't forget the dust filters, especially if you live anywhere near a
    busy road...

    Couldnt you just get the wife to stand next to it fanning it? Thats what I
    do.....she moans like f&&k but then what else is new?

  5. If you were to do that then you shouldn't connect it directly to your pc
    because your fans wouldn't have sufficient draw to pull up enough air through
    the pipe. If on the other hand you stick a in-line 230v trunking fan, then
    you're going to create wave disruptions in the air flow (that is unless you
    don't connect directly to the back of your pc, but leave sufficiant space
    behind it so that it can balance itself out). Are you running a Cray X1 or

  6. Hmmmm my pc is humming, must be the cpu fan?
    Nope, it's half a dozen bumble bees, 4 wasps and 18 flies :)

  7. The OP's post smacks of geeky overclocker to me. Just another way to get
    attention to how fast he can make his kit go and at a temperature of 0.1
    degrees below his nerdy buddies.

    If the OP has 5 fans running and his kit is *still* overheating then I
    suggest he reconsiders his whole machine build. He might as well spend the
    £450 to get a vapochill if he really wants to impress.

  10. 1) Why bother. Mine's at 34 (41 on a really hot day) and works just
    Yes; most axial fans (and certainly the ones on a PC) do not generate
    enough pressure to drive air through even the most modest length of
    trunking. If you want to move air that way you need a mains voltage
    centrifugal fan (look at the pressure rating on an 8CM case fan - a few
    mm of Hg if you are lucky. You get bigger pressure differentials than
    that when a car drives past 10m away.)

    I've been thinking of fitting a water cooling block and have it all
    running through a Mini (car) radiator mounted outside the window.

  12. Why? My shuttle XPC sits at 50-55'C (hit 70'C this summer during the super
    hot days) all day at full load with only one silent fan and the PSU fan

    It has bene running like this 24/7 for the last year with no problems. I
    really don't know what all the fuss with temps is to be honest. I even
    ripped the fan off my TI4200 and stuck a passive Zalman onto it and that
    runs fine too.

    bugs...dust.....and what are you going to do when the outside air
    temperature gets a little warmer than it is now?

    FWIW, my CPU temp is currently running at 33c and I don't have ANY
    fans other than the CPU fan and the one in the PSU. Its also also a
    lot quieter than it would be with 5 fans

    Yeah, bugs, of the spider variety i would imagine.
    Imagine all that lovely warm air in a dark, cobweb filled tube.

    Dust filters are a great add-on to a CPU fan. The close finned HSs we
    see nowadays don't take long to get clogged with shite, seriously
    reducing their efficiency.

    I use a 50 to 80mm adapter - - mounted on top
    of the fan, and an 80mm filter - - to give
    maximum area and flow.

    Where are the case fans sited? The single biggest improvement to my
    system cooling was to mount a 50mm fan in the top of the case. I made
    the hole in the case fitted with a grill, but mounted the fan on a flat
    piece of aluminium folded at each end so that it sat, like a saddle of
    the inner top case rails.

    (If you have removable side panels then the above would not be helpful.)

    Anyway... The top mounted fan bought case ambient down to below room
    ambient, and CPU temperature lower than with the case cover removed. I
    also like to make sure there are no open PCI slots at the bottom of the
    case letting all the cool air before it does some good.

    A compromise with the outside air duct would be just to duct the CPU
    HS-fan outside the case. There is a uk.c.h poster who has some details
    of such a mod on his web-site, but a quick Google didn't find it. :-(

    my original solution was to water cool but the expense is holding me
    back...idealy id like a water cooled cpu with the radiater outside of the
    windowso that i have a silent pc.

    my computer is not far from an air grill so i would only need a metre of
    pipe and would be an easy cheep solution. my office is small with limited
    space and is boxed into a small space so it is hard to introduce cool air to
    the area. even with 5 fans running the internal temps are consistently 33c.
    cpu is 55c. looking increasingly like im gonna have to fork out £170 for a
    water cooling kit.
