QUOTE(asunakirito @ Feb 16 2014, 07:31 AM) Non-pwm is better than PWM. Why are you swapping them? For your case, that is. but PWM fan are always better, PWM fan has no cold start problem, meaning you dont have to worry about your fan cant spin if the supplied voltage is too low. non-pwm fan may have already stop spinning.  |

QUOTE(asunakirito @ Feb 16 2014, 09:23 PM) Not sure for Enermax Cluster, I have 2 Cluster 120mm, tried on mine, it won't come out. Don't dare to put too much force in it otherwise spoil. According to their site: http://www.enermax.com/home.php?fn=eng/pro...a1&lv0=4&lv1=32I also have Enermax Magma 120mm, that 1 easily come out compared to Cluster. Use very little effort to pop in and out. I'm currently thinking of getting 3 140mm Enermax T.B Silence (Turbine instead of Batwing). But could not get much info on it, whether its pwm or non-pwm. Not much review/benchmark for this fan.  They have manual mode, 3pin and pwm version. You can get the pwm version if your mobo is Asus that support AI Suite 2, so even pwm fan can be operate on voltage mode. |

QUOTE(ntw @ Feb 16 2014, 11:57 PM) what's the difference between magma n cluster? and where do u get these clusters from? Starting from M5A99X i think, or any asus mobo that supported by AI Suite II, PWM fans can operate between voltage mode and PWM mode, that's one of PWM fan advantages, but when PWM fans operate at voltage mode, it will have cold start problem just like any other 3 pins fans.Asus mobo can control pwm fans using voltage?! Btw it's not something new, as pwm fan header have a fool-proof notch to let you insert it into 3 pins fan header  |

QUOTE(ntw @ Feb 17 2014, 01:33 AM) So i guess you r saying that 3pin non-pwm fan can also work on 4pin pwm header.. But in voltage mode the fan can work but the fan speed can't be controlled right? Yeap, it works but it will spin at 100% duty on most regular mobo,but latest Asus ROG mobo can auto detect whether if the fan is pwm or 3 pins, because it has a switch on the pwm fan header. while Gigabyte mobo can change between PWM and voltage mode on BIOS, but i tried on their 890FX UD7 only, other mobo not too sure |

QUOTE(henshin80 @ Feb 17 2014, 10:57 AM) allow me to ask newb question. buy y splitter, http://www.gelidsolutions.com/products/ind...=2&cid=11&id=63 fan splitter has some limitation, cant connect too much fan else the fan cable melt or mobo spoil, while pwm splitter cannot control more than 5 PWM fans simultaneously.im using bitfenix outlaw casing with lots of fan space. but the thing is my motherboard doesnt have enough chasis fan pin to connect the fan. how ah? or get a fan controller. |

QUOTE(asunakirito @ Mar 20 2014, 08:07 PM) Tried NOiseBlocker, much louder than Noctua, not recommended. If you have fan controller, can use NoiseBlocker to lower rpm around 1000+/-. But the performance delivered in terms of airflow and static pressure is still lower than Noctua. Also to take into account, most fans out there takes more watt/power compared to Noctua (e.g. NF-A14 FLX uses 0.06amps at 12v = 0.72watt. Bitfenix takes almost triple of this, NoiseBlocker at full rpm is 4.5watt (similarly to a HDD power consumption.) Which model of NoiseBlocker fan you were testing?The only limitation I can see with Noctua is oil leakage, since they use oil to reduce friction between the fan blade pillar and the housing of the bearing, there is a risk of leaking oil. I had 1 NF-P14 in my Noctua NH-D14 leak oil, but the 12cm NF-P12 did not have this issue. I had Enermax fans which I used for like 4 years, and does not have this issue. If only Enermax had reduce their power usage similarly to Noctua, I would buy them instead since its much more friendly to clean with their patented pop-out fan blade. I currently have 2 M12P multiframe running, you could say they are louder at full blast because the model im using are 2000RPM fans As for leaking oil, my Noctua NF-F12 PWM also leaking oil after several months of usage. Another downside of Noctua fan is, it require high startup voltage especially the 140mm 3 pins model, i had 2 of them, their fans wont even budge until i my CPU started to warm up |

QUOTE(aizielectreon @ Apr 26 2019, 11:49 PM) i got 8 fans..using Lian Li 011 casing.. You can try to use tweezer to press the connector pin's wing then push it out, but all use molex. so full power spin, and its quite loud. its there any recomended fan controller for 9 fans? https://en.wikipedia.org/wiki/Molex_connector#Disk_drive By default is 12V, if you change the pin location to 3 + 4 it will become 5V, 1 + 4 is 7V, just make sure the polarity is correct before power on. This is easier than redo the connector that can connect to mobo fan header, those requires to buy specialized tool and JST pin + connector which normally only hardcore hobbyist does that. |

QUOTE(aizielectreon @ Apr 27 2019, 01:04 AM) erm...is there any device that can do all this? There's no way to alter the voltage/amp of the AMP connector (not Molex, but both looks similar). You can daisy chain all the fans together, then just switch the final connector wire position(1+4 or 3+4), you only have to do it once. Blame Lianli with their stupid idea lol/ |
