Being that it's new it's probably still covered under warranty. Sounds like the motherboard is the suspect.

Displays momentarily and asks for CPU fan connection. I have changed 4 fans and still get the same error message and the display goes off.


You're sure you have the cpu fan connected to the correct socket? sounds like it's not connected, or is connected to a different socket. Does the fan turn?

Motherboard Power Problem


Hello Alienware,

Could be a few things.... such as the micro-fuses that have gone on the MB....

But what I dont understand is this:...."Then I disconnect the 4-pin cable that goes from the Power Supply to the motherboard near the CPU and the pc turns on fine"

How????
You have just disconnected the cable from the PSU to the motherboard....it CANT turn on! LOL.

Do you mean that the lights turn on?
Or you hear the HD spin up (if you left it connected to the MB that is)?

Please advise so I can help you more.

My Asus A7V8X-X AMD Athlon 2500 motherboard was custom built. There are three fans, front,CPU, rear. There are only two motherboard connections, 1 chassis, 1 CPU. rear is disconnected. How can I connect...


If your rear fan has a small 3 pin connector and there are no connections of that type on your motherboard, you will need an adapter to connect it to a four pin molex connector from your power supply. Something like this...

Cpu fan stop few second after starting pc


Hello,have you installed new motherboard or CPU?
Follow these steps again
1) Disconnect the power cord from the back of the computer & open up the case.

2) Wear an anti-static glove or at very least discharge your static by touching a metal surface or power supply

3) Disconnect the main 20pin ATX power connector from the motherboard & the square 4pin ATX2 power connector

4) Remove any PCI cards you have & disconnect ALL drive cabling from the MOTHERBOARD. Also disconnect any internal USB fly leads from the motherboard.

5) You should now have ONLY the cpu+heatsink/fan, memory & video card installed. Locate the round silver battery in the bottom right corner of the board. Just below it, you'll see a plastic jumper cap. This cap should be covering 2 pins (pins 1 + 2) with pin 3 bare. It will be marked JP1. Move the jumper to cover pins 2-3 instead. Leave in this position for about 30 seconds, then return the jumper to its original position (pins 1-2).

6) Reconnect the square 4pin ATX2 power connector & the main 20 pin ATX power connector. Make sure that the case speaker or buzzer is connected also.

7) Make sure the only external devices connected are the keyboard/mouse & monitor. Reconnect the power lead & power on the system

Let me know what happens

I have a K7VZA motherboard when i turn power on


The very first thing you need to do is unplug all drives inc power.
Now remove as many add in cards as you can without compromising the system.

Try to boot at that point.
If it boots re-connect each piece of hardware one at a time until you find one that causes a problem.
Double check that item for any issues and replaces if needed.

If you have had the fan off the cpu for any reason then you should have cleaned both the cooler fan underside and the top of the CPU and put fresh thermal grease made for that purpose on there. DO NOT use too much as that is almost as bad as too little.

Is the fan the correct type eg motherboard takes 3 pin and fan is 4 pin ?

Make sure it is connected to the CPU FAN pins on the board and not system fan.

If you have another computer and the fan can be removed from the cooler itself you could plug it into the system fan port of another computer to try it out.

under no circumstances should you run a system without the CPU cooler running as it could cause irreparable damage to the CPU

ASUS P5KPL-AM CPU fan connection.


You should still be able to connect the 3 pin connector of the fan to the 4 pin connector on the mobo, the keying tab is offset so that you cannot connect it to the wrong pins.
If you still don't want, or can't connect it there, simply go on the Bios (press delete after you turn on your computer) and you will find an option to monitor CPU fan speed.
If you need any more help, let me know

Extra wire /fan 3pin hole 1wire where to plug in X 2 fans


If your cpu fan has a 4 pin connector & your mb has a 3 pin you can still use it. Just leave one pin exposed. The extra pin is for a speed control sensor that not all mb's support. The chassis fan has a different connector on the board marked "cha fan". This one is a 3 pin connector. Most of the asus boards have 1 of these. If you wish to run more than one you can either buy a "y" adapter that allows you to connect 2 fans to 1, you could use an extra 4 pin molex to power an extra fan but that would give you no control over the fan, or you could buy a fan controller and hook all your extra fans to it. Hope this helps & please take a moment to rate my solution fixya. Thanks.

I'm building a computer, using a p5e3 deluxe with wifi. I have the bar minimum hooked in, and when I turn on the computer, I end up with the ps fan coming on and the case fans working, but the cpu fan does...


Make sure you have the cpu fan plugged in. With Asus the plug should be right beside the RAM sockets. It will be marked with a small cpu fan and will be either a 3 or 4 pin connection. If your cpu fan has a 3 pin plug & the motherboard has a 4 pin connection you can still use it. Just leave one pin not plugged in. Hope this helps.
