    High volume/airflow fans worth it?

    I'm considering getting a new intake, due to the fact that I only have 1 intake and 3 exhaust. I was considering the Delta one which shifts 190CFM air but produces 59dBA noise. I know that my current fans are 17dBA (for the 2 12cm ones) and 19dBA (for the 2 92mm ones). My question is, are these high performance fans worth it when the increase in noise is taken into account? Thanks.

    Your 3 exhaust fans will just be 'sucking' more air through the intake. The Tornado will make a difference but you need to be aware that you'll be putting more air in than you will be taking out.

    I would get a tornado and a fan controller - set it to 7v and you should be quite happy.

    trust me, a 92mm tornado on full blast will seriously get on your nerves after a few minutes, they shift an awesome amount of air, but they do sound like a jet engine, like a high pitched whistle as well as the rush of air.

    An extra intake fan wont make much (if any) difference in temps. Thanks too the miracle of air pressure, You're already drawing in enough air. If something is to hot, consider a better HSF for that not another case fan.

    Ok. I was just concerned whether the fact that the 2 92mm fans are essentially reducing the air pressure was detrimental and wheter you should have a higher air pressure to keep dust etc out. I'm not having any heat problems, although a nicer GPU cooler may be considered in the future, although the current one is very good at it's job.

    Dust filters work best, for keeping dust out. If you're not having any temp problems then everything is working as it should be and it's not worth the noise.

    You'll always get some dust, a quick blow every now and again is enough or you can be posh and get some compressed air.

    when there's dust a 100+ CFM fan cant rid off.. no blowing will help that much.. I had to spend a fiver on a can of compressed air off maplins every month just to get the loads dust out of my tsunami..

    i agree about the extra dust with the tornado, i had a sp-97 and that was usually clogged within a month, even with a dust filter on.

    Having positive pressure in the case will keep dust from being sucked in from
    all holes and you will only gain a degree or 2 in case temps.

    I would get rid of one of your exhaust fans get an evo for the cpu and duct it
    directly out.
