Hi,

Yes that is a good thing that you can hear the fan going as its cooling the system down.

If you have noticed that its louder than normal then you may have to clean the fan blades of dust. It should be a little quieter after that.



Regards.

Why will my fan not run during use but i hear it when the computer powers up?


Fans, mainly the CPU fan, have a speed control which slows the fan down. This is usually controlled by the BIOS. The speed is based on temperature of the CPU. If it's cool with little load the CPU fan will run very slowly and you won't be able to hear it. On startup all fans ramp up to 100% until the BIOS takes over and slows the fan down.

How do I control fan speed?


Keeping the fans clean is especially important, because the fans blow out hot air and bring in fresh air to cool down the laptop.


Fans attract dust, however, which can slow them down, resulting in a hot laptop.

If the laptop overheats, vital parts can cease functioning altogether.


Consequently, keeping your laptop's fans clean is crucial.



The fan speed on a laptop can determine how it operates consistently and reliably.

You can slow it down or speed it up, based on the circumstances.


For instance, slowing down the fan speed may be useful in reserving processes or during a prolonged slow time.


Speeding it up is beneficial in keeping the laptop cool during ongoing use or high-traffic times. For the long term, find a happy medium for regular use, so you won't "psyche" out your computer by constantly adjusting the settings.


Click on the Start menu and select "Control Panel." Next, choose "Performance and Maintenance."


Select "Power Saver."


To slow the fan speed, locate the slider next to "CPU Processing Speed" and slide it down by moving across to the left.


To speed up the fan, move the slider to the right.


Press "Apply" and then "OK," if prompted.


Hope this helps

Engine temperature reaches to high before cooling cycle begins


could be a bad temp sensor or faulty thermostat. so by cooling cycle do you mean electric fan, or water circulation. a bad thermostat will slow circulation down causing overheat even if cooling fans are on. a bad sensor will not operate electric fan properly or at all and car will get hot at idle or slow speed and cooler at higher speed. Keep in mind that electric fans can turn on at any given time so KEEP ALL FINGERS AND LOOSE CLOTHIG AWAY at all times.

I am using a Dell Dimension C521 Desktop and the other day I noticed the fan started constantly entering a cycle where it would kick into high speed and then slow down again every 2 minutes. After trying...


The fans change speed depending on the temperature the sensors detect.
Give your machine a thourough cleaning.
The CPU sensor is usually located under the CPU if it's loaded with dust it may think it's hotter then need be and kicks the fan up.

My computers cooling fan keeps speeding up and slowing down is that a good thing or a bad thing


I'm assuming your desktop has an AMD processor?
AMD have a process called "quiet and cool" this basically speeds up the fan when the processor is under load and getting hot or slows it down when the processor isn't working as hard.

Why does my fan seem to be cycling at all times which is slowing down the computer big time


your fan has nothing to do with your computer slowing down.
your fan goes on when a threshold is reach in the cpu temperature or another component's temperature being cooled. the question is what's is causing your cpu or your chipset to work harder than usual causing your system to seem to be sluggish??

the simple answer is malware and need for a clean up and tune up

I suggest you do the following:

1. get an air can, open the case and without touching anything and watching for ESD, dust off your system free.

2. close the case and turn your computer on

3. update your antivirus and run deep scans

4. get all critical updates for your system from windows update

5. download, spybot search and destroy, malwarebytes, superantispyware, and a square free edition, update them and run deep scans.

6. defrag your hard drive

7. to improve perforamance make sure you update or upgrade memory

good luck!

Fan races slows down races again


the fan is supposed to speed up when the processor gets too hot, then slow down after it has cooled a bit. if it is running more than normal, maybe you should take the cover off the pc and clean the dust out of the cpu heatsink.

Compaq Presario 3000 incredibly slow firing up, opening up anything. Loud fan all the time too


This advice relates to the Compaq Presario 3000 Notebook series but may also apply to other notebook computers as well.

The heat sink and fan assembly is probably clogged with dust and airborne particles. The clogged cooling parts can lead to heat problems with the CPU. When the system (CPU) gets to hot, the fan has to kick into high gear to try to cool things down. Once you remove dust and debre from the heat sink fins and fan, you will immediately experience better cooling and less fan usage. Your system may also be set for dynamic switching of CPU speed. If you CPU gets too hot, the system will reduce clock speed and ramp up fan and everything will slow way down. Use a good system monitoring software such as Notebook Hardware Control to monitor your CPU temperature, HDD temp and so forth. When the system starts getting too hot, first look at clogged heat sink fins as possible culprit. If you're good at electronics you may be able to service the unit yourself. Get a copy of the system's Maintenance and Service Manual or have a professional do the job for you as you will have to partially disassemble the computer to clean out the heat sink. Depending on the system, the job can take as little as 15-20 minutes once you become proficient at it.

I think my cooling fans are out


These fans often have variable speeds based on demand, so a change in speed or even stopping may not mean anything.
Look for dust/dirt around the fan vent.
Are there any signs of overheating?
