| 586558 | 2007-08-31 06:00:00 | Hi I have a computer using the Intel DG33BUC motherboard (G33 chipset), and every fan I plug into the case fan socket makes a very annoying clicking sound. I think this is the motherboard using a too low voltage for the fan (it's running at about 1200rpm). I wouldn't mind running the fan faster, but throwing it on the +12V line is too noisy, and quite unnecessary in terms of cooling. This needs to be a quiet computer, and it is apart from the clicking. There is no option in the BIOS to control how it controls the case fan, and no BIOS update mentions this problem. Any ideas? |

| 586559 | 2007-08-31 07:25:00 | where is the clicking actually comeing from? whats wrong with 12volt line, motherboard sockets are generally 12v. i doubt its voltage is to low, normally thay have current limits, put too big a fan on and it fries the header on the motherboard. |

| 586560 | 2007-08-31 08:50:00 | The clicking sound is coming from the fan, but I've tried three different fans, and they work fine running directly from the 12V line. The noise stops if I hold the fan still after it stops trying to spin. Motherboard sockets are 12V maximum, but they adjust this voltage by PWM or other methods to keep the noise down. Plugging the fan straight into 12V is quite loud. The fan isn't drawing an excessive amount of current. Those sockets are good for at least a few hundred mA normally, if not 1A, and this is under 100mA. |

| 586562 | 2007-08-31 09:33:00 | Will do later on when I'm down in the house. | george12 (7) | ||
| 586563 | 2007-08-31 11:20:00 | Hey I have used a couple of those boards and had the same problem. I didn't have any other fans to try and figured it was faulty case fans. In the end I just left the case fan disconnected as they were running everything at stock speeds and wouldn't be overclocking. |

| 586564 | 2007-08-31 11:39:00 | Interesting to see it seems to be a design flaw with the board. I might try a BIOS update just in case it fixes it, otherwise I will see how it goes without the fan. The PSU has a decent 120mm fan, so it might be OK. | george12 (7) | ||
