I have one 3 in x 3 in fan running on one 3 pin connector.My question is can i also run that fan plus one or two 140mm 12v fansI'm looking for a total cooling of the computer at the cheapest amountI can get the fans for like 6 bucks on OKorder and the cable for 6 bucks too. so what 12 bucks and my computer is as cool as the snowI am just curious if the plug will burn out if I am running too much power on it?
The motherboard has no capability of detecting whether the fan is on or not. Now, that being said you can rule off the fan problem. I believe the reason your computer shutdown could be because of one or more of the following: a) If this is your first time running a game the CPU could have overheated and in most cases caused the computer to shutdown. In some cases (very rearly) the CPU could have been destroyed but I highly doubt this. b) The computer shut down you say? Maybe it was a cable from the back of the machine that had caused this. A No signal detected is a common error for this type of scenario. c) Electrical failure - This can be caused by one various computer compoments and caused the computer to shutdown or possibly malfunction. Since you have new pieces I suggest trying in a dummy CPU to see if it works. You can go to a computer store and ask to try a CPU before you buy it to see if it resolves the issue. I hope I helped ~
You would have to add up the ampere ratings of the fans. If they add up to more than 0.4 ampere, they would most likely overload the 3-pin connector on motherboard. The motherboard may be able to carry the load for quite a while until connector melts. Better hook them up to an adapter so that they connect directly to the 4-pin molex connector of power supply. The power supply won't have a problem running about a dozen of those fans. Take note that the yellow wire is +12VDC.
