    looking for a good 2x 140mm PWM fan

    Looking for a good quite and powerful 140mm PWM fan!
    For dual front intake
    I want it quite fan while browsing or doing light work!
    I don't mind fan noise if I want to play games or heavy load.
    Preferably around £20 for both delivered
    NO LED!!!!!
    Am looking at
    Akasa 140mm Viper S Flow AK-FN063
    Arctic F14 PWM
    any over recommendation are welcome!

    I have a bunch of the Arctic F12 PWM fans, and I'm fairly impressed with them, especially considering the low price. They are on par with the AP14s they replaced - although louder at high speed.

    If the F14 fans are anything like their 120mm stable mates, you won't go far wrong.

    I've got a BeQuiet 140 Shadow wing as a top exhaust. I never hear it.

    Re: looking for a good 2x 140mm PWM fan

    Well the big advantage of PWM fans is that if you've got good PWM control you should be able to run them at very low speeds (600-700rpm) for near silent operation without motor buzzing (often caused by under volting the motor)
    Remember you generally need 4pin headers on you motherboard to use them.
    While some of the very expensive fan controllers (we're talking £100+ range) work by pwm on a 3pin fan I've never seen it done on a motherboard because of all the additional power regulation that's needed.
    3pin Fan headers on motherboards (and the vast majority of fan controllers) are controlled via voltage reduction not PWM so there is no point getting a 4pin PWM fan if you are connecting the fan to a 3pin header.

    My choice would probably be the Viper, While I cannot confirm the current Apache and viper, the original Apache was made by Scythe and used the same great Fluid Dynamic Bearing as was used on the old S-Flex line.
    Side note sycthe also make some fans for Gelid and Thermalright (depending on model)

    Not sure on the Arctic F14 PWM, the 120mm version is good for a cheaper fan but the 140mm is a very different fan not the same fan scaled up.

    The Thermalright TY-140 is supposed to be good http://www.scan.co.uk/products/140mm...ssion-fan-blad and there's a higher speed version in the TY143 http://www.scan.co.uk/products/140mm...45-db-case-fan
    Note, these do have 120mm fan mounting holes not 140mm so may or may not fit, depending on the case and hole placement

    Thx for the interesting facts,
    I'm using Asus Z87 pro mobo, got 4x 4pin fan control + 1x 4pin cpu + 1x 4pin cpu optional
    my past experience asus fan control is not bad, hope the new one isn't a let down
    already had a look at the thermalright should fit, but it seem the blade is a bit smaller

    Yes really quiet seem it on my mate case,
    just feel I need to more powerful fan if I do use 2 SLi graphic cards.

    I agree Corsair fan looks awesome!
    Will get them either for top exhaust or side intake!
    Problem they don't have PWM like the smaller 120mm

    Beware the default image there is incorrect. It is showing the more expensive Silent Wings 2 fan instead.

    Hmmm. TBH I've had it about a year so can't be sure of the model, but the price is about right.

    wrong images and description happen too often and every so often wrong pricing.
    worst thing is they either refuse refund or charge us the delivery!

    It's easy to tell the difference, just count the fan blades.

    Re: looking for a good 2x 140mm PWM fan

    although corsair are not 4 pin you can get a silent edition if you want a quiter setup
    or the performance edition for cooler setup

    truth, after my friend had problem returning it.
    But most consumer buy based on pictures rather then description

    I pretty sure they only have 1 type for 140mm range

    correct they only do the AF140 Quiet Edition for 140mm

    That and saying
    although corsair are not 4 pin you can get a silent edition if you want a quiter setup
    or the performance edition for cooler setup
    is stupid as the OP is talking about low noise when idle/light load and higher air flow when under high load.
    The easiest way to do that on a z87 motherboard (the majority of z87 motherboards use PWM on all fan headers) is to use a full set of PWM fans so the speeds can be slowed right down when idle and sped up when additional cooling is needed.

    Granted things like blade shape and count do have an effect on air flow and audible noise but still the single biggest key factor is rpm.
    Under good pwm control a fan should be able to run around 600rpm at it's slowest which will be quieter than the AF140 and depending on the full speed rpm could well provide better air flow at full speed.
    This can be done automatically at a hardware level which is the major advantage of motherboard with PWM fan control over software or a separate fan controller. (granted hardware level automatic control can be provided by some fan controllers but they are not that cheap and the extra cost needs to be factored in)
