| 412453 | 2005-12-13 20:43:00 | Just added a small little cooling fan to my old PIII box. It works Ok except that it produces a high-pitch noise which is quite annoying. What's the remedy? Cheers |

| 412456 | 2005-12-13 22:18:00 | Well there are 3 possibilities: 1) Fit a similar sized fan which has a lower rpm setting. You may have to sacrifice CFM for low noise. 2) Volt mod the current fan to 7V (www.ocforums.com), this will make the fan spin slower and thus it will be a lot quieter (again at the expense of CFM) 3) Install a bigger fan. 120mm is recommend (these fans spin at low rpm but they still move larger amounts of air than the smaller 80mm or 92mm fans) The 120mm fans provide a good balance between effective cooling and low noise operation. Hope that helps |

| 412457 | 2005-12-13 22:45:00 | I just had the CHA fan start to make noise today, and it kept me from booting. The sensor would shut the boot off after a few seconds..but I still heard something noisey for the few moments it was trying. I took the side case off..hit the power and found out which fan was making all the noise..removed it and gently pulled off the foil cover on the back of it. I placed two tiny drops of sewing machine oil on the bearing using a toothpick to place it where I wanted and re-installed it. It's running quietly and happily..so am I..er...happy that is. Maybe it was due for an oil change anyway. :D |
