| 1128753 | 2010-08-18 07:06:00 | The running the two fans in series effectiveley runs the fans at half voltage & in theory at half speed. Idea No 2...Ascertainn the Ohmage of the fan & get an equal Ohmage Potentiometer , variable resistor, & run it in series with one fan. PJ |

| 1128754 | 2010-08-18 08:03:00 | Not being ungrateful or anything, but how do I go about setting this up exactly? | 8ftmetalhaed (14526) | ||
| 1128755 | 2010-08-18 08:52:00 | something about connecting the red wire to the black wire :D | jareemon (5207) | ||
| 1128756 | 2010-08-18 08:53:00 | I think you basically would connect the positive wire from one fan, connect it to the negative wire on the other, then use a plug for the remaining two wires and plug it in, but dont take my word for it, | jareemon (5207) | ||
| 1128757 | 2010-08-18 09:40:00 | Ah. Well I'd rather not go butchering my nice new fan's wires. I will keep it in mind though, depending on how much a controller will set me back :) | 8ftmetalhaed (14526) | ||
| 1128758 | 2010-08-18 10:33:00 | If your mobo supports it, try using software to slow the fan; www.almico.com |

| 1128760 | 2010-08-18 11:26:00 | It connects to a 3 pin connector, but are there 3 wires coming off the plug (usually something like red, black, and yellow)? If there are only two wires coming off the plug, then it'd be missing the third "control" line . That is incorrect . That 3rd wire is for the RPM readout, it is not used to control fan speed at all . You can vary the speed of any fan by reducing the voltage or using a PWM controller . I tried speedfan, but it didn't work . None of my fans reduced in speed, despite their RPM's appearing . It worked on my old PC, so I'm confused as to why speedfan doesn't work on my new one . Any ideas/solutions? What is your Motherboard model? You need support from the hardware monitor chip as well as extra circuitry to change the fan's speed . Often the low end boards use a monitor chip that can control speed but the rest of the circuitry to do the actual voltage control isn't there, so while Speedfan reports it as changeable, it actually won't change . |

| 1128761 | 2010-08-18 12:41:00 | It's a gigabyte UD4 p55 mobo, cost about 300 bucks when I got it I believe. | 8ftmetalhaed (14526) | ||
| 1128762 | 2010-08-18 13:57:00 | There are other reasons why the speed may not change 1) Often a board may have several fan connectors but not all are speed controlled. Often they can report speed (for fan failure detection) but can't change voltage. Check your manual to see which ones are speed controlled or not, likely not all of them are. 2) Speedfan incorrectly detecting your chip (unlikely if it can read the current speeds) 3) Speedfan not changing speeds very fast. My MSI board actually takes a couple of seconds for the speed set by speedfan to kick in. In any case, I would do a test on all your fans. Individually set them to 0% speed and see if they stop. (Of course, set them back to 100% straight away!) You may need to wait several seconds. The CPU fan at least should stop. If even that doesn't work then there is something wrong with speedfan probably. (Are you running Vista\Win7? may need to run Speedfan as Admin) |
