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.

A cooling fan of a computer should be running on a constant speed it should not speed up and speed down, this is a clear sign of a fan that is already getting bad and that wont be able to maintain the good cooling system of your computer, I suggest you think of having that fan replace.

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.

When we turn on our heater on the temp is fine but when we turn the heater off the van overheats.


You may have an engine cooling fan that isn't working. When you run the heater you are removing some heat from the cooling system which aids in keeping the engine cool. If the cooling fan in front of the radiator isn't working then the engine can overheat at slower speeds when there isn't any air being forced through the radiator by the forward motion of the vehicle. If this problem is happening only at slow speeds then I would suspect a cooling fan BUT if it happens at steady speeds over 35 mph you may have a different problem.Hope this helps and good luck!

GE JVM1430 over the range microwave/exhaust fan unit. The exhaust fan (not the microwave cooling fan) all of a sudden has its speed slowed down considerably. The unit vents out the back, not top. ...


Sounds like a strip down of the fan and lubricate the bearings with sewing machine or thin cycle oil will do the trick.
Hope that helps.

Computers cooling fan keeps speeding up and slowing down is that a good thing or not


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 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!

Dell precision m90 overheats randomly


Either your motherboard has gone bad, or you fan AND cooling grid needs replacement. The grid is simply a series of metal bars, so to speak, which absorb heat to be passed out of your system with the cooling fan. The cooling fan has 2 speeds. If the system is not kicking in the higher speed on the fan, it's more than likely a bad motherboard. Also, make sure you keep your laptop plugged into the wall as much as possible. Going on battery alone does slow down the processor considerably to conserve the battery.

Best wishes.

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.
