Fan not spinning

post #1 of 6
Thread Starter 
hey all..ive got a not to bad OC goin here .. at 2.25ghz..temps are startin to get near 50 durin gaming..but i opened up the kit and noticed that my "exhaust" fan on the back of the case isnt spinning? i checked and the cables are plugged into the MOBO..why isnt it workin? my little fan on the front/bottom of my case right under the power switch is working just fine..and the heatsink of course is working..any clues on what i need to do? how much will this improve my temps?? thx


just to add..im using ITE Smart guardian for fan speed control

What does Smart Guardian say? (DOes it notice the fan is not spinning?)

Fans do die. I have had more than my fair share go out.

Try different power hookups (if you are using a MB connection, try a different one - if it still doesn't spin it is dead. you can also connect your current working fan to the connector the dead fan is on to rule it out and know that the fan is dead.

i dont know how do what you just said.. sorry newb still in some areas. smartguardian only recognizes that my Heatsink fan is working..but in reality the other fan is working too but it says its RPM is 0000 so i donno what that means. is it hard to change the connections to my fans? maybee i can find someone who is more knowledgeable than me to take a look at it..good news is i took off my side case and my temps wont go above 40C on full load.


is 1.6AGP voltage too high?


thx!

Not gonna get into OC stuff since a dead fan is.. well.. a dead fan

Trace the cable from your dead fan. It will either go to the motherboard or to a connector from the power supply.

Here is a pic of what a MB hookup looks like...

If you are on the MB, try to see if there is another connector.

Try to trace the cable from the fan on the front of the case and try to hook it up to wherever your current fan is hooked up. Does front fan still work? If so, you have a dead rear fan.

Or, hook the dead fan up to the power source that the front fan is hooked into. If it works, that means you have a dead connector and you just need to find another (either on the motherboard - or buy a molex splitter from a computer store.. looks like this.)

And keep in mind, so long as you are not bringing a massive amount of static or magnets into your case, it is pretty hard to screw it up.

The fan is really just like a house fan.. it has a few wires that plug into something.

Edit:
And for speed monitoring software to watch it, it has to be hooked into the motherboard somewhere or to a third party chunk of hardware (a fan controller, etc.)
