Casefan horror Hello, I'm building my new system. (see below) When I connect the 3-pin connector of my 3 chassisfans to the motherboard (to CHA1_FAN) and power up the computer, my 3 casefans (120mm 1200rpm) make a terrible noise, especially the one at the front! (~60db+ ) Are they swirling too fast with too much voltage? They come with the gigabyte case, and are supposed to be silent. When i disconnect this cable and boot up, the pc is very silent, as it should be. What can i do about this? I've tried CHA1_FAN, CHA2_FAN and PWR_FAN on my motherboard with similar results. ----------------------------- CPU E6600, Scythe Ninja rev B CPU cooler, Twinmoss 2x 1gb DDR2 PC6400, Hiper 480Watt PSU, Asus P5B motherboard, Nvidea 8800GTS 320mb GPU, Gigabyte Aurora 570 case |
Look in your BIOS if you can alter the speed. Or buy a fancontroller.... |
are you connecting ALL three fans to the same header?? |
No bios options to alter speed. They are alle connected by one plug. It gets split in 3. I think the noise comes from chassis vibration. Will try to unscrew the fans and listen if the noise remains. |

I will try to connect them seperatly (if possible) tonight and see what happens. I could buy some conversion plugs to hook it up on the PSU. Thanks for the tips! |
What does gigabyte have to do with Asus P5B ? ;) |

I doubt that this would be the problem though. I suspect that massive chassis vibration is producing all the noise. |

And, there are more motherboard fabs than Asus and not every motherboard will be able to supply 7A on one header ... What fans are you using and what speed are they running at ? |

I solved the problems: 1. The front fan suffered from a half-loose dustfilter. I had to dismantle the case to access it. 2. The rear fans were not properly screwed in, thus making them vibrate. Poor build quality from gigabyte! Thanks for the tips. I connected one of the fans directly to the PSU. The other 2 remain connected to the MB. |
