Re: Cpu Fan error
Do you have a manual for the mother board?? Sounds like someone forgot to plug in the fan or you didnt say if the fan was working on the microprocessor or not?? If its not working then the plug for the fan should be right by the socket fore the processor. If it is working then theres a setting in the bios that has to be reset. I would take the board to or ask the person you bought it from about it. Did you buy the board with a case or all pieces separate? Good Luck

Three causes of ovheating: 1) Dust. Dust inside the computer, Dust around the vents, fans, cpu and heat sink. Take a can of compressed air and clean the dust out of the computer.
2) A Fan not working. Make sure the fan inside the Power Supply where you plug the power cord in works. Also there is a fan that sits on top of the CPU and Heat Sink. Make sure it works. Normally the system will give you an error message if the fan is not working.
3) Thermal Paste - The Thermal Paste around the cpu and heat sink has dried up or is too thin to keep the unit cool. Apply a fresh coat of Thermal Paste on the CPU and Heat Sink.
The fault could be the cpu, wrong type of ram, a faulty ram module
or a fault in the mainboard.
Check all the settings in the manual and the bios aswell.
Here is a list of beep codes: Basic Beep Codes for ABIT AWARD BIOS Motherboards
No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board
One beep - board is working fine
One long beep then machine shuts down - faulty, improperly installed or missing CPU
1 short(Beep) System booting is normally
2 short(Beep) CMOS setting error
1 long - 1 short(Beep) DRAM ERROR
1 long - 2 short(Beep) Display card or monitor connected error
1 long - 3 short(Beep) Keyboard Error
1 long - 9 short(Beep) ROM Error
Long(Beep) continuous DRAM isn't inserted correctly
Short(Beep) continuous POWER supply has a problem
A two-tone siren, generally caused by overheating or out of specification voltages
Four beeps then machine shuts down. This is because this version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header or clear CMOS to reset to default (no checking).
Open cover and switch it on, check if fans turn (assume CPU fan), if not switch it off and remove from mains, replace faulty fan or clean the fan with a small brush and vacuum cleaner might be clogged with dust. If this fails check bios settings for CPU temperature and adjust accordingly, do not exceed recommended CPU temperature, or CPU will overheat and eventually be destroyed.
Computer shuts down and beeps due to over heating and bios shuts down machine as a precaution.
You are right when the laptop first starts up it is the fan, if you are getting error message then it is the heat sink (fan on top of cpu) that will need to be replaced.
I would only recommend changing it if you know how as getting to the motherboard is quite tricky to say the least
Please dont listen to the geeks at bestbuy, they obviously dont know what they are talking about
If this has been useful please leave positive feedback/vote/testimonial - Thank you again
I agree with both of you. As long as you are not experiencing any heat event (shutting down and rebooting) just ignore the error message. If the fan is on and running at a fair speed, you shouldn't have and problems. Now should you start to have heat problems, don't boot the computer until you have a larger CPU fan in place...and too you may be able to add an additional fan to the system for reassurance. the added noise is worth the security of not having a CPU meltdown. Those large 120 are very quiet and move air, if you can find a place to hang it. Good luck, hope this helps. please leave rating -thank you kindly
hi my name is gary i will try to help you out with this problem......
the first thing that comes to mind is the cpu could be over heating... this could be caused by the cooling fan not working correctly ..if this is the case what is happening is that the bios has a setting that looks after the temperature of the cpu and if it get to hot will shut the pc down to protect any further over heating and of course other components within the pc tower...to check if the fan is working take off the side of the pc while it is turned off you will now be able to see the large fan located on the mother board...now switch the pc on and see if the fan starts up ...if not this will be the problem ... just pop to your local computer shop and they can easily fit a new one for you.
also if the fan is matted in dust this could also cause the pc to over heat and shut down.....if so just turn the pc off and get a small paint brush (new not used) and clean down the fan and the heatsink.
You must have the CPU fan plugged into the CPU fan power connector or the system can not monitor the fans speed. Your PC will shut down & give you that message. (The fan must be connected to the correct power plug). If when you did replace the CPU's fan & had to remove the heat sink, which is where the fan screws into & did not clean the old thermal grease off the CPU & heatsink & replace with new thermal grease than your CPU will still overheat. If you add thermal grease over top of old thermal grease your CPU will over heat. This is all a balancing act. If any one is not correct your system will shut down. (This is better than killing the CPU). To remove old thermal grease use a clean cloth damped with house hold alcohol & use the same on the bottom of the heatsink. Please allow plenty of time for the alcohol to dry.
Hi MonaMona,
Replacing a CPU fan is easy, but be carefull, the CPU will have old thermal grease on it, so unlatch the CPU at the same time you take the fan off. Because the CPU will come up with the fan, so unlatch the CPU pins, to release the CPU pins, when taking the fan off. And when putting the new fan on the CPU, & the fan nust be smaller then 80mm, the sell just CPU fans. Make sure you put on thermal grease on the CPU, so it won't over heat & will protect your CPU, also don't cake on the grease. Put on a small amout & spread it on the CPU thin. Let me know if that does it for you.
