Cpu fan heatsink spinning at abnormal top speed

My computer has been working fine for more than 2 years. Suddenly my cpu fan started going really fast, like even when no memory is being used. It just keeps on spinning really fast. I opened the case and checked for dust and used air compressed can to clean up an dust on my mobo or the heatsink. When its really hot and humid( I live in ottawa, Canada) the speed of cpu fan keeps on increasing until it once reached 2900 rpm and i just shut off the computer. One thing i noticed that one of the sensors named "Remote" is showing 98-100 C. i use speedfan software. It could be because of that but i am not sure. Would changin my fan solve the problem? if yes where do i buy it? thx a lot for your help!
Intel celeron 3.06 Ghz

i have only one air suply fan at the back and the heatsink which is causing noise problems. Everything else works fine, akk the programs inside. display problem

i think your PC must be going off after some mins or half hour ...

if this is true then this is due to the Video adapter IC (integrated circuit) failure ...
this happens if the video adapter IC is getting over heated on the motherboard ....

so you need to replace that video adapter IC then everything will go on fine ....

you need to contact the motherboard technician and get the video adapter IC replaced ......

if the heat sink is only making noise then remove the processor with the heat sink and check for the obstacles if there are any obstacles then clean it and refit the processor then i think you will not get this noise again .....
before removing just have a check is that the heat sink making noise or some other device (it may be hard disk too ) so it is better to have the check before removing processor...
do it if you are good at removing it otherwise no way you must and should contact the technician only ....

i think it s easy you can do it ...

any doubts you can reply me
i am always here to assist you
thank you
rate my solution ...

I'd change the fan. It could be the thermostat is acting up.

Fan not running , cpu very hot.Will that cause the fan not to run and laptop proline m548s switching off?

Oh nooooo !! If your fan never turns on, then get the problem fixed, but please don't continue trying to use the poor computer.
A CPU can get hot in less than a second, and if used without suitable cooling will eventually kill itself. Your computer turning itself off is a built in safety feature, but this usually only happens when the CPU is already dangerously overheating (when I say dangerous I dont mean it will explode or go on fire, I only mean it will damage the CPU beyond repair inside).
Some fans only start spinning when needed to save power/electricity/battery so those types have to wait until a certain temperature has been reached in the CPU before it will start to spin, which can make it appear that the fan is broken.
The first thing to check before replacing a fan is see if its blocked with dust/fluff - for towers or laptops, but laptops tend to be far worse for collecting fluff.
Make sure all fluff is removed from the heatsink area of the fan assembly, it should be completely clean all over - the fluff will collect in the heatsink fins.
If that's all ok (and this should always be done anyway), check that you have some kind of heatsink compound between your heatsinks base and the CPU - this is essential on most computers - the compound helps take heat from the CPU onto the heatsink to spread the heat away - and the fan helps keep the heatsink cooler.
Another thing is, as its a laptop, make sure that wherever you use it, you don't have any air vents being blocked up. Many many users have them on a lap, or cushion etc. and don't know that the air vents underneath are then blocked, causing massive overheating problems soon.
One of my most common jobs is to clear all the fluff from air vents on laptops, so that's what I would check first though. I get many that have a solid wall of fluff insde, some as much as 1cm thick. Some even have damaged CPU's from the heat as the owner has kept turning it on again and again, but actual damage is very rare :-)

Computer beeps every 30 seconds

It is car brakes. Turn that game off.


BIOS speaker is broken, and you hear high pitched beeps?

CPU temperature in normal............
What is the CPU, and what is the temp? Hey, I gotta know so we are on the same page here, lol!

Those repeated high pitch BIOS Beep Codes indicate a CPU problem.
I would remove the Heatsink/Fan combo, and replace the Thermal Paste.
(Following Anti-Static Precautions, and cleaning the CPU, and Heatsink, of course)

Also make sure the Heatsink is sitting flat.
Yes, I know what you stated about Speecy, and Core Temp, but I would try it anyway.

Still no?
CPU is sounding Taps, and telling you goodbye.

My cooling fan on a HP Pavillion a1133w never shuts off and is louder that what i would expect. I'm not familiar at all with the decibal count from different towers/fans. It was given to me and works...

Yeah usually towers are pretty loud; but loud is good, because then you know your fans are working and you do not want the fans to stop spinning.

Try installing drivers for your CPU, or look at the settings for your video card, or look in your BIOS; there may be a setting or driver that enables automatic control of the speed of the fans, based on the heat.

My computer suddenly dies within 1 / 4 hour

Hi. Thanks for your question.
My first guess on your case would be overheating of your motherboard which could cause "sudden dead".
To proof my guess we need to check temperature on motherboard and chips. There is a very fine and free program that can do this it is called speedfan and you can download it hear ----->
Once you downloaded it and installed have a look at temperatures. Are they rising up to the point when computer shuts down?. If yes it isn't all that bad. On some motherboards speedfan let's you control speed of fans :-). so you can run your PC cooler. If this is not the case with yours please check for dust in the case. Are fans clogged up? Is computer standing in the corner with no access to air? Get it unplugged and brush gently of the dust. Keep it clean and your temperatures should improve.

Hope this help. Good Luck and please do not hesitate to ask more questions if you still didn't find an answer. Thanks

Overclocking on this board with an E2180?

When the CPU overheats it shuts down especially if you overclock it.
Did you put any heatsink compound between the CPU and the heatsink (this aids heat transfer from the CPU to the heatsink/fan)?

Your BIOS may have a setting that can adjust the CPU fan speed/temperature.
You can install additional fan/s in the case to draw more air into the computer case.
To further cool the CPU, you might have to install a better and more efficient cooling heatsink/device/fan on the CPU.

Computer shutting down automatically

Remove case side and clean out ALL fans then remove fan from heatsink DO NOT remove heatsink (probably stuck on CPU) clean all fluff and dust from heatsink.
Use a stiff brush and vacuum cleaner on power supply fan area
then vacuum out case include all vent holes and behind power supply. test start.should be OK

Cpu fan noisy/chip fan fail error messages


Yes. This sounds like a fan issue. The noise often comes from bearings failing within the fan. Also, a failing bearing can make things harder on the motor as it brings the fan up to speed. This is likely the reason that you see increased warnings during the fan speed check while booting because it comes to speed more slowly as bearing wear increases.

I give this a 90% chance that your CPU fan is causing the issue. Since a decent CPU fan will cost you ~$20 online, it's not much out of your pocket if you happen to uncover another culprit.

I'll keep an eye on this post. Let me know how things go.

CPU fan stops, computer shuts down

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.

Good Luck! Take your time.
