Re: CPU fan failure
The bearings in the fan or internal mechanism may have burned out. If the fan does not generate a cool enough environment, you run the risk of frying the processor and other motherboard components that are temperture sensitive.

Hello Sounds like you need a new cooling fan.You may be able to save yours with some electrical contact cleaner spray. Remove fan and spray. The cpu will heat up quick and shut down everything to protect itself.Im sure once you get a new fan you will be up and running again. You may consider reapplying new conductive paste to the processor while you have the case open.
see do one thing check the cpu fan whether it is working properly and is not producing any noise if it is then probably you need to replace your cpu fan with a new one also makke sure that your power supply fan and chasis fan is working as excess heat gets generated in the system they remove it
to change the cpu fan
1.see it will depend on what kind of cpu socket you have pin or pinless
for pin-open the plastic clamp on the fan
for pinless -unscrew the heatsink
2.remove the heatsink and replace it it will be much better if you replace the full heat sink with a new one .also don't forget to put thermal grease compound for effivient heat transfer in between the cpu and the heat sink contact generally these days heat sinks come with pre-applied thermal componds but still it is recomended to apply it firmly over the cpu before installing the heat sink on it
3.if you wish to install the old heatsink by just replacing the top fan then replace the fan and rub the bottom of the heat sink with a sand paper to make it even and free from dust and oxide apply thermal compond and install it on the processor .plug bak the cpu fan header cable .
start your system it will stop overheating..
..plz do check the following as in order:.. the Hardware part:.. 3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..change if required..
dust neatly..dust is non-uniform in nature n may cause jam/short
circuitry/excess resistance n many more..resulting an increase in heat..
open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink
Compound" (available in local electronics chip level spare market)
between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it
tightly in position..
8)on main/mother board..see with a debug
card for mb error..may bshort..look for defective capacitors(esp
above1000mfd)/mosfets..go through the mb's south bridge n the circuit
lie around atx connector..the crystal clock generator (if cpu isn't
heating up).. if u r not a professional, always better to seek advise from ur system admin/vendor....
One of the most common failures is Power Supply. Try first, unplugging and leaving off for a few minutes before trying to start it again. Sometimes this helps, but I expect you will need to dig deeper.
this sounds like one of two things to do with heat:
the cpu cooling fan, is it working all the time,
a fault with the motherboard processor socket causing the overheat.

It sounds like you have a couple of potential problems. First it could be the fan is not working due to failure or not being plugged in properly. Second is that you need to put Thermal Paste between the processor and the heatsink. If you have not done this before, I suggest seeking out a friend that has to help out. There is many kinds of thermal paste and not one is universal. Find out the one that the CPU manufacturer recommends.
When you say power is going to the mobo, are other fans and lights turning on? You also may have forgotten to plug in the large ATX power cord from the PSU, or the smaller 4-pin rectangular 12V power cord. Is the correct local voltage setting for your PSU selected (110 or 220)?
Todays CPU fans are set to automatically up their RPMs if the processor overheats or is overtaxed. But the trick is when the fan itself is not cooling enough but rotates and makes this sound like a heicopter. Since you see it turning, you may not realise its cooling is poor. The best and long last solution is get a brand new fan and install it. The baby will stop crying.
