QUOTE(Ryo @ May 31 2007, 09:37 PM) bro where to get those fan controllers for performance high amp fans like the deltas? scared if i use standard one it will die on me. in terms of the Delta FFB1212EHE (3.0A), there are NO fan controllers in the market that OFFICIALLY support them. wanna DIY the controller oso u have to look for the right parts which from what ive gathered aint that easily available. |

QUOTE(Ryo @ May 31 2007, 09:37 PM) silverstone got fan controller bundled in their fans. so if you want quite can turn the RPM down for quite operation. but it's reassuring to have the power when you need it....if you need more airflow just increase the RPM with the risk of noise tat's y.. when nid higher cfm from it means more noisier.. zzzz... but all in all, not a nice fan.. |

I'm using that Thermaltake smart fan, fully run will noisy, so i just turn it around rpm 1800~ 2000 is ok. If want use high RPM fan, use with controller will be nice.

Most boards since the Athlon/Pentium 4 have them. But fans taking more than 0.5A may have problems, >1A is not advisable at all to plug into motherboard connectors.bro where to get those fan controllers for performance high amp fans like the deltas? scared if i use standard one it will die on me.

You can still use the onboard PWM controller, but plugging it into the board directly will mean that the fan will not get enough power, or possibly even shorting out the circuit (not likely, but possible). What you'll need to do is to use the board's PSM signal to drive a power transistor that controls the fan itself.wanna DIY the controller oso u have to look for the right parts which from what ive gathered aint that easily available. There is an alternative design, a standalone PWM design.

The noise lv of dis fan may too high if at highest speed , about 1.8 sone . But the volume of air blowed almost 31 cfm . Anyone ever use Arctic Cooling 80mm led fan?

Tat fans controller i'm not sure bcz no data shown at offical web and i no yet surf for reviews.  Since dis thread is concern about CFM ... i dun think tat add the controller can increase the CFM . If u interest , can refer to karom's thread for Aerocool Silver Lightning rated at 19dBA@ 1m distance and 61 cfm volume blowed . http://forum.lowyat.net/topic/454798 This post has been edited by duo8668: Jun 4 2007, 10:22 AM |

 QUOTE Time and time again many customers have asked, "Hey Sidewinder, Do you have a fan controller for the Delta FFB1212EHE?" Until recently the answer was no, mainly due to cost. While there are several ways of doing so, the easiest and most reliable way seems to be a variable potentiometer. After high demand we have introduced this rheostat assembly from Ohmite. This rheostat is capable of handling exactly 25 watts of power. We have tested this with Delta part #s FFB1212EHE and TFB1212GHE. One of our test rigs confirm there is a wide range of control from 1932 RPM at full low to 4017 RPM at full high on the FFB1212EHE. Specifications Ohmite # RHS10RE (RoHS Compliant and Lead Free) Resistance: 10 Ohms Power: 25 Watts Features: Open Frame Voltage: 500 (RMS) Diameter: 1.560 inches (39.62 mm) |

anopther thing to consider is where you put the fan. the position is important as well. not juz the number of fans ryte?
to put down the noise, maybe we can install the fans on rubber pads. to absorb the vibration.. maybe then, the noise level will drop down.. or we can also put eggcart inside the case. thats how they soundproof cheap jamming studios.  fan controller? wowee!! but it looks like sumthing that we can make.. |
