    there is a brand call be-quiet...the fans actually will carry on spinning for 3 minutes after shut down, this is to remove the heat in the casing quickly to lengthen the life of the components
    my superflower psu is temperature controlled with manual speed override, even on low speed its noisier than my gigabyte cpu cooler, so i think brand matters and i chose the wrong brand/model... any recommendations on locally available ones welcome.

    Sounds like my theory and crude design in connecting the fan to a PVC pipe to cool the CPU. This will enable full concentration of wind to the CPU

    i have E800 too and the noise cancelling feature is known as voice clarity...doesnt make much diff to me (eg. using the phone in MRT)

    I am using a Thermaltake Silent Tower...running at 2250rpm.....it kept my Precott 3GHz at ~50C......but unfortunately it's not silense at all

    Hmm, you don't need a 12cm fan for that though a direct aiming tube like what you're suggesting is a good idea because it will bring cooler external air to cool your CPU most efficiently. You'll be surprised how effective a simple mod like that can do to cool your CPU a fair bit more than normal. It's funny how this simpe CPU airpipe idea (you can even read about the specs for one at Intel's site) is so old yet so few case manufacturers have actually provided for one over the years. It's only lately that I see a lot more cases having that.

    Even if you're going with this, the noise of the heatsink fan is to me usually the most crucial noise factor and because of that, a large efficient heatsink with a low spinning fan is IMO, the only way to go.

    Personally I don't like water cooling. It's too high maintenance for my lazy lifestyle. I like to keep things as simple as possible to minimise problems.

    The other thing I like to do to keep fan noise low is to run some of my 12V fans at 5V. My two front intake fans are running extremely quietly as is the bottom of HD fans.

    And finally, choose a low noise power supply. I like Tagans. They are extremely well made and very very quiet. Fairly reasonably priced too compared to the super exotic ones.

    been there and done that...u will regret when the external fan suck in all the dust and clot your fans + other components...therefore now i make the fan blow OUT instead of suck in

    one of my heatsink fan already got this "tube" build in...so i just need to attach the tube to the case fan at the back

    Aiyah this Zalman not as cool as this one

    Eh, fan blow out, air still must come in from somewhere man, and hence dust too.

    Personally I think dust is unavoidable. Best to keep the room environment as clean as possible.

    Every half a year or so, I pop the hood open and vac the accumulated dust.

    yup..i have the tagan too..cable are twisted to reduce clutter and got auto fan speed control so the noise is minimal

    i got wire guaze for the front in-take fans to filter the dust, it is washable too, better than using air-con filter or stocking....

    i have this in my main system and it does reduce the dust accumulated inside...compare to my brother system, it already got lumps and lumps of dust inside without the filter
    We are HDD of PC & FT are MB add to storage;
    so PC never hangs with enormous storage capacity - LKY

    Actually one of the best things I ever did for peace and quiet was to abandon a very very pretty (and rather pricey) aluminium Coolermaster case for a Chieftec steel case. My take is that most thin walled alu cases let out too much sound. The damn Coolermaster case was so noisy it wasn't funny.

    Pity, it was the nicest case I had ever owned. I gave it to my best friend when I built him a PC from my old components after I upgraded.

    I lost touch with PC's for quite a while.. Does the Zalman cost as much as the Soldam cases? You know... Those Soldam cases that cost S$1000++ w/o PSU..

    I am amazed at your gf hearing, is she a musician?

    An unofficial wisdom from manufacturing, if you can't get rid of something, try to mask it. Just turn on some music, much cheaper than any of the super duper cooler or noise reduction phone.
