auxiliary fan not spiinning

Hi.
just recently replaced power supply in my pc which has an auxiliary fan and now fan is not running.  I might be connecting power cables incorrectly but wanted to know aside from the connection to power supply, am i also supposed to connect fan to auxiliary fan1 3pin connection on motherboard?

I presume this auxiliary fan is meant to blow air either in or out of the case.

These types of fans usually are connected to motherboard if there is a connection point on it.  They don't have to be.  They can be connected to the Molex connectors on the power supply - these are the connectors to the floppy and hard disk drives.  You'll need the proper adaptor, this depends on the pins on your fan connector.

See http://www.amazon.com/Ultimate-3Pinto4PinAdapter-3-Pin-4-Pin-Adapter/dp/B000BSJGL0 for example.

If I tried both the 4pin molex and 3pin motherboard
and still doesn't spin should I try the auxfan2
Connection instead on motherboard? How can I
Test if fan is broken? If I don't use fan will pc overheat?
Yeah go ahead and try the auxfan2 and see if that will work. The fan may be dead or there may be a short in the wire. Was the fan working before you replaced the power supply? The only way to test it is to just try different power connections, and maybe turn the blades with your hand a little while the computer is powered on to see if something is causing it to jam.

You shouldn't have a problem with heat as long as you make sure the CPU fan is connected and working properly. That being said, you can take the fan to Best Buy or any computer electronics store and they will help you get a new one for pretty cheap. More airflow is always better in computers.
