Posted May 18, 2013 Everybody on newegg seems to say the D14 doesn't have a PWM fan? I'm not quite sure what this means, if my impression is right, this means it ahs a 3 pin fan not a 4 pin fan? If it does then how does that affect it? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted May 18, 2013 It doesn't say on their pages, but if the provided fans aren't PWM, then they're 3-pin, yes. That being said, I have the cheapest Noctua cooler, and both the fans on that one are PWMs, so if the top tier cooler doesn't have PWM, I'd be surprised. How it affects performance isn't that big of a difference, it'll have just as good max performance, but it might be a little louder at any lower RPMs than it would be otherwise (and not as energy effective).

Posted May 18, 2013 the Noctua NH-D14 is a 3-pin fan kit, both the NF-P12 and NF-P14 are 3-pin fans. the Noctua NH-D14 SE2011 is a 4-pin PWM fan kit, both the NF-P12 PWM and NF-P14 PWM are 4-pin fans, but will not attach to any other platform other than the 2011 LGA. you'll have to order the secure2 kit to attach the SE2011 kit to say a 1155/1366/AM2/AM3. only difference between the 3-pin and PWM (4-pin) fans is how the fan control system is implemented. 3-pin through voltage control and 4-pin through cycle percentage of the on/off modulation. airdeano Link to comment Share on other sites More sharing options...

Posted May 18, 2013 PWM allows control of the fan speeds. Its quieter and more efficient. Get the SE2011 one with the PWM fans • i7 4770k @4.5ghz 1.248v • Noctua NHD14 • ASUS MAXIMUS VI Hero • Asus STIRIX 980 Ti • • Corsair Vengeance Pro 16Gb • Samsung 840 250gb + Samsung 1TB 7200RPM • BenQ XL2430T 144Hz • • Fractal Design R4 • CoolerMaster GX650 80+ • Razer Deathadder Chroma • Filco Ninja 2 Red • HD600/HE-4/ Fiio E17 • Link to comment Share on other sites More sharing options...

Posted May 18, 2013 Nocua lists all this on their website so you can get the correct model numbers for what you want. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted May 18, 2013 Your Motherboard should Use either Voltage or PWM to contol CPU fans, so i wouldnt worry about it.

Posted May 18, 2013 Included in the box are 2 Ultra Low Noise Adapters also that will lower the rpm fan speed. When I had mine I just left the fans on 100% all the time because they are really quiet anyways but after you get done OCing you could always through the ULNA's on if you want.

Posted May 19, 2013 As above, but also, don't pay attention to mini reviews on retailer websites. They're written by idiots, usually. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
