in my case speed of cpu'fan is zero,but it work .why?

the cpu fan has a sensor in it that tells the motherboard what speed the fan is spinning. the sensor can go bad and the fan will still work. your going to need to replace the fan. Most motherboards won't let the computer boot up with a 0 fan speed

check if the cooling fans are working properly.\n\nthing is, you might have to get a better cooling fan for your processor, or move your PC to a cooler place.

Sounds like you have to tweak the flux capacitor on your motherboard to make sure the output is 1.21 jiggawatts. Make sure the hard drive is spinnging at 88 miles per hour as well or nothing is going to happen.

Some brands has own power management programs with option to turn fan always on. Some has this option in bios. But I never seen option to turn it instantly off. I wouldn't do it. Even if you have good wind tunnel built for cooling. Factory fan is situated right in the place for most efficient cooling. Show mercy to your CPU.

Check the external temperature - working in a mildly warm environment can play havoc on today's 3.0GHz+ these days. You might want to try upgrading your processor fan.\n\nAlso, some programs place an extremely high demand on processors.\n\nOverclocking also does this - but I doubt you overclock.

Sounds like your running hot, so clean all fans and the heat sink, if you don't have a back fan fit one if you have a spar front bay fit a bay in put fan, this will make a pull through of air, try it it works, Cybercat.

i would be checking the cooling fan first.if it is not running thats your overheating problem.not knowing how old your box is?-what version of windows or are you using windows  makes it pretty hard for us to answer.have you overloaded it?have you done a recent defrag-there could be several reasons.

1. Check the fan, if the cooling system is bad the processor will automatically step down its speed\n2. Remove all spyware and viruses by installing a good antivirus software\n3. Make sure you un install all software that you dont need. Any thing that runs in the back ground such as database services etc.\n4. Check how much RAM is currently being utilised and which processes are taking max cpu time. That might give you an indication which program is slowing it down.\n5. Check memory for consistency by doing a memchk from command prompt. Also check that CMOS setup detects the right amount of memory installed (2GB in your case)\n6. Try using Firefox browser. Its more resilient to spyware etc.

I've checked the spec on your motherboard and it has a socket 939 processor. You have a relatively high spec piece of kit and I am surprised you do not have a fan controller panel.\n\nPersonally I would ditch your current CPU cooler and install something better. I have provided a link to a suitable good quality cooler with a 3.5" fan controller panel. It's on special offer this week. If you're not confident about installing the cooler, take your PC to your local computer dealer and get them to do it for you.\n\nHeat can greatly reduce the effectiveness and operating ability of your CPU, and therefore your PC as a whole, which you don't want if you are a serious gamer. Over time CPUs constantly running hot will have their live reduced significantly. For the sake of £20.00+ you can save yourself a lot of grief and improve your PCs performance dramatically.

I'd start by looking at the fan and giving it a clean if its necessary.  If you've changed memory sticks, then they could be defective - there's always the option of a virus infection as well

Check your bios. There is a numlock setting there.

Check your processor fan....since AMD heats up quickly...\n\nif possible change it these days AMD's company recomended fans are coming in market....\n\nComputer hangs just because of heat up....\n\nuse new fan...with new heat sink...\n\nchange cabinet if possible....for better vantilation\nor if possible fit extra fans in your cabinate\n\nu didn't tell what os u r using??\n\nand which net connection u r using??\n\nhanging of computer has nothing to do with virus\nits very rare case\n\nPlz look for new fan with heavier original AMD heatsink\n\nand make cabinet more vantilated...with more fans

Dust is bad for you computer. The fan could in the long run stop working and would cause the cpu to ovderheat which could cause the cpu to stop working or worse.\nPurchase a can of compressed air. \nShut down you computer.\nUnplug your computer from the outlet.\nOpen the computer case and spray the dust off. Keep the nozle of the can 20 inches away from the cpu.\nAlso you might want spray the fan of the power supply and inside the case in general.

I think there is some problem with your fan. I am using computer in bangladesh without AC and sometime in summer I run my computer for 3 to 4 hours without any problem. Consult with your vendor and if you are covered with warranty claim co change your CPU fan.

The second answer is pretty much correct, but I can assure you it's a fan probably the processor fan if not the power supply fan.  \n\nMake sure the fan for your processor is securely seated on the processor.  If that's not the fan check your other internal fan to make sure the are secure.

Your cooling fan failed on your computer.  This could be the one in the power supply, or some other fan in the case.\n\nYou'll have to open it up, turn it on, and see which fan is not spinning.  Check for loose connections to the fan.  Give the fan a spin to see if it is stuck and just needs encouragement to start spinning.\n\nIf that does not work, you will have to replace the fan or power supply.

There is also a program at www.Zdnet.com called \nSpeedFan 4.28  it moniters fan speeds and temps
