| 581003 | 2007-08-14 20:46:00 | I have a case fan in a PC I want to slow down. It is already running at the slowest speed I can get it to run at using software (Speedfan), however I would like to slow it down further to reduce noise. I had an idea of simply wiring a variable resistor in line to the fan, so I can throttle it up and down. Does anyone know whether this will work, and if so, what size resistor do I need to go for? | somebody (208) | ||
| 581004 | 2007-08-14 21:11:00 | What fan is this? CPU? Case? PSU? | CYaBro (73) | ||
| 581005 | 2007-08-14 22:44:00 | What fan is this? CPU? Case? PSU? I think that he/she already specified that it was a case fan. Have you considered buying a fan speed controller? You can get them off Tradme for about $30 and then you can turn them up/down whenever you want. I have one and its really handy - when gaming i turn the speeds up a little, but when just surfing on Press F1, i can quiet it down a little. Controllers like: Link1 (www.trademe.co.nz) Link2 (www.trademe.co.nz) |

| 581006 | 2007-08-14 22:52:00 | I second Link2 (www.trademe.co.nz) - I've got one and it's brilliant. It also lets you turn the fans right off, and can control cathode lights etc. :D |

| 581008 | 2007-08-15 00:24:00 | This is a SFF pc so any sort of "proper" fan controller is going to be too big to fit, hence why I wanted to try an alternative such a a small trimpot or something. | somebody (208) | ||
| 581009 | 2007-08-15 00:29:00 | Whatever you do remember that a fan needs more V to start spinning than to keep it running. Slow it down too much and it might be iffy starting. | PaulD (232) | ||
| 581010 | 2007-08-15 00:53:00 | What pin connection does it have, 4 pin molex, or 3/2 pin for motherboard connection. Just asking cause I have heard of people just using the 5v cable instead of the 12v to slow them down... | SolMiester (139) | ||
| 581011 | 2007-08-15 02:00:00 | 2pin - plugs into header pins on the motherboard. | somebody (208) | ||
| 581012 | 2007-08-15 02:01:00 | Sollie's got it, just rewire it. As pointed out by Paul, be aware of the starting voltage though, some fans will find it difficult to start at >5v, though simply swapping 12v feed for 5v will give you 7.5v or thereabouts. There are plenty of instruction for doing such things on the interweb. Start Google or Silent PC Review, actually the latter will probably get you there quicker. |
