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

Hi...
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
bye
rate my solution ...

I have a hp slimline 3100. the cpu fan runs fast everytime i open a program or play a cd. it speeds up the slows down. sometimes it runs really fast, then the computer shuts down. whats going on?


This is an indication of overheating within the PC. Open the PC case and clean all the air vents. Take the heatsink and fan off the CPU and give it them a good clean. Put the heatsink and fan back on to the CPU and start up the PC. check that the fan on the heatsink is running smoothly.
Also, make sure the vents on the power supply are clear and the fan on the power supply runs well.
If you go into the BIOS setup, you may be able to monitor the fan and the CPU temperature.

Fix OVERHEATING Notebook


This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:
  1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
  2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
  3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
  4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A135) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

When turn on my computer after a seconds the system is shutting down.. i don't know what to do, is there a problem with the processor?


A overheating CPU will shutdown and won't start up again until the CPU has cooled down.
The overheating problem (ie. thermal shutdown) is most likely caused by a faulty CPU fan or dust clogging the CPU fan and heatsink.
Check the BIOS CPU fan speed could be set too low, check the fan speed/temperature setting.
If this problem is not fixed, then the CPU will eventually fail.
Check the fan to see if it spins freely, if not then replace the faulty fan.
If the fan and heatsink are cligged with dust, loosen and remove the dust and use a can of compress air to blow away the dust.

How to recover my intel pentium D 2.8ghz processor its over heating of 70 degrees.


If your system is five years old or older it is possible that the thermal grease/tape has dried and will need replaced. There is no need to remove the CPU for this. If you can enter your bios you can also check the fan speed of your CPU heatsink fan rpm. It should run between 2800rpm and as high as 3500rpm. If its not than replace your heatsink assembly.

How do you troubleshoot the processor cooling fan-to see if it's spinning fast enough?


Go into bios and under advanced functions it will tell you CPU fan speed and CPU temperature

Compaq presario cpu cooling fan will not start spinning unless "helped" with tip of pen to spin over.If I dont start it manually,I get No cpu fan message,and shut down.I just replaced fan,as old had broken...


If the CPU fan speed is too slow or not working at all, the computer will shut itself off automatically to prevent damage to CPU from overheating. You may end up having to throw more money at the problem and get a new fan. I went to Compaq's web site, looked up your particualr computer, found out what type of fan you needed, and I did some research. I recommend getting the fan in the following link. It's very cheap, and has good reviews. The other fans on the site all have bad reviews. Hope this helps.

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.
