| 827482 | 2009-11-05 21:44:00 | Hey, how can I connect 3-4 case fans that all have a molex end, to the motherboard.? What do i need. I have a psu that has about 3-4 molex cords with a 3pin connector right at the end of them. |

| 827483 | 2009-11-05 21:52:00 | I have not seen any adaptors that let you run molex fans from a motherboard header, only the other way around. Even if you did do it, You would also have to make sure that you're not drawing too much current from the board. I suspect each fan header on the board is only designed to take 1 fan. Putting 3-4 on one would be a bad idea. I just daisy-chain all the fans together and then plug them into one PSU molex connector. If the fan wires are too short, I extend them. All you need is some more wire, a soldering iron (if that) and something to insulate them (I use heatshrink) |

| 827485 | 2009-11-05 21:57:00 | So this wont work? PSU>molex>fan molex>end of the same psu's cord 3pin into motherboard. Or what about fan molex end>molex to 3pin adapter>motherboard. |

PSU>molex>fan molex>end of the same psu's cord 3pin into motherboard If that involves what I think it involves, you'd be trying to power the fan power header with power from the PSU, and a fan in the middle. I expect there would be a lot of magic smoke |

| 827487 | 2009-11-05 21:59:00 | There are adapters to run fans with 4-pin molex connectors with the 3-pin male headers on motherboards. But running anymore than one fan from one motherboard fan header is not a good idea. I think the max load you should put on those motherboard headers are 0.5A. You'll probably be safe plugging in two 0.2A fans on one, but I personally wouldn't do it. | qazwsxokmijn (102) | ||
| 827488 | 2009-11-05 22:02:00 | How many fan headers are on the mobo?? If there's 3-4 then you can connect 3-4 fans. As Agent said, it may draw too much current, if you connect too many to one header | Speedy Gonzales (78) | ||

As Agent said, it may draw too much current, if you connect too many to one header P5Q-E CHA_FAN 1,2,3 PWR_FAN CPU_FAN How ever the cpu fan is on CHA_FAN 1. Can you get 3pin to 4 pin for the CPU fan to go on the CPU_FAN for speed alteration, so I can save CHA_FAN 1,2,3 for case fans. |
