Volcano 7+ odd wires question
OK, so I have a Thermaltake VOlcano 7+ I got recently.
Now, in addition to the variable speed switch between the fan and the HD power plug, there are two odd wires I don't quite get, aren't described in the sheet of paper that came with the fan, and I can't find explained on the Web. One comes out from the fan, I believe has a white three-hole clip, and the other comes from the speed switch and has a brown three-hole clip. Now, obviously the fit on the three pin plug on the motherboard for "CPU fan". But...why two of them? When I have the one from the switch plugged in, all three speeds of the switch works, although the BIOS can't detect the fan speed. When I have the one from the fan plugged in, only the highest speed works, but the BIOS detects the fan speed just fine. So, what's up here? Unfortunately I have only one place on my mobo for CPU fan or I'd try them both at the same time. Thanks for any clues, including simply a URL to someplace that might describe what they are/do. Thanks, Liam |

ink.net... http://www.thermaltake.com/products/heatsink/v7plus.htm Thanks, but unfortunately, unless I'm completely missing it, I don't see an explanation for these two plugs on that page: http://www.overclockercafe.com/Revie...no7+/1017.html (Odd, I'll have to open the case to make sure, but I could have sworn on mine BOTH of those plugs had only one wire each.) Thanks, Liam |

I was right the 1st time: there's a single yellow wire coming from the fan with a white three-pin plug, and a single yellow wire coming from the switch with a brown three-pin plug. Here's a new development I'm not liking so much...with the brown plug coming from the switch on the mobo, on the medium speed the fan will stop running after 30 seconds. If I play with the switch some, it'll start up again. Bad part perhaps? Come to think of it...that hasn't started happening until I got the new PSU. Weird.... On the highest speed it stays on just fine (but man is it LOUD!) Well, thanks for any feedback! Liam |

Seems when it's in medium, which is at one far end of the switch, it works fine if you press the switch hard all the way, but it eventually moves a micrometer off the spot and it stops working. It comes back on again if you press hard in the direction again. I guess the switch is off center in the shell or something. Dunno what I can do about that...except exchange it. Sorry to bother. But the question regarding the two single wires still stands. =) |

Dang man, it didn't come with a manual/diagram?

So since most 3-pin fans don't have the power and pulse leads split to two plugs, the switch needs to do the splitting. So the single-wire plug from the switch would usually go to the fan monitoring plug on the motherboard. The V7+ fan, however, has two separate plugs, one for power (two wires) and the other for RPM monitoring (one wire). Usually these are combined into a single 3-wire cable, but because some PSU-3-pin adapters don't handle the RPM wire (and given that the V7+ will probably burn out your motherboard if you plug it directly into there), the designers put in the additional plug. So now the fan's single-wire plug goes to the motherboard, and the switch's single-wire plug goes out of the way somewhere, unused.

That's a great explanation and answers my question perfectly. =) Thanks! Liam |
