On some computers, when you first turn it on your fan spins loudly, and then goes quiet. However, mine goes loud and stays loud, and then I have to keep turning it off and back on until it goes normal.

I was wondering if anyone had this problem or if anyone knows how to fix it?

I have a quick question for you.

Have you ever tried turning it on, and applying pressure around the area that the fan is held at?

The reason i ask this is because my grandma had the same problem with her computer, and you could apply pressure to it and it would stop making so much noise so we replaced the Power Supply (i believe) and it stooped making the noise, so maybe you should just consider replacing it? (It being the fan) because they are really cheap!

Is the fan properly in place? Is it plugged into the motherboard properly, or is it an old fan? Did it ever used to be quiet? I'm sorry its just that you weren't very informative. You did not provide much details at all. Next time please at least give some information to help us. Besides your problem, for example what used to be like, what happens now, what you last did to it.

I have the same problem with my other computer never knew why but with my search results do the following.

Clean hte fan with a brush
use a air can to finish it off try it out still to loud
use a single drop of sewing machine oil in a tiny hole in the center of the fan

If that don't work replace the fan.

[Dagoth Nereviar]

Sorry about not being descriptive

It's a new case, with the powersupply (and I think maybe the old fan too, but with an extension on the case side).

Next time I turn it on, I'll try applying pressure...Then if that doesn't work I'll open it up and take a look around. I was going to do that, but I decided to ask first, so I didn't end up screwing around without having to

Thanks to all those who replied, will update when I've done the above ^.^

The other problem could be that your power supply does not provide enough wattage therefore it will heat up above a normal temperature and next cool down. Therefore, the fan will run continuously until you turn off the computer and let the power supply cool down.

[seanooi]

another one i could think of is that your processor core is heating faster than your fan trying to cool it down. Some(or maybe most) motherboards now monitor processor heat. If it gets too hot the fan will spin as fast as it could in attempt to cool down the processor. Or maybe there isn't thermal solution applied onto your heatsink. Trying giving those some thought too. Hope it helps.

[Dagoth Nereviar]

I've looked about inside and nothing's loose, but it probably is something to do with the fan not being able to cool it down as quick as it heats up.

However, it's not doing it as much as it used to (it just does it the one time when I first load it up, and then the next time it usually stops)

So you're saying that your fan keeps running at a high speed even after your computer is booted up?

I guess a couple of things could cause that:

1. Like someone above said, it could be a power supply issue, your fan is not getting a constant wattage so it keeps toggling the fan on or off. You may also have a bad power supply that is losing alot of power when trying to boot your computer or run more intense applications that are nescessary for your fans to run at higher speeds.

2. Your computer may just be running really warm. Do you know any internal temperatures of your computer? What is your motherboard running at? How about your CPU? The fan could just realize the high heat and keep running in order to try to cool down your case. Not very probable, but possible.

Try finding out what temps your computer is running at to see how hard your fans are needing to work.

Problems With My Computer Fan

The 2 fans on my dell laptop xps m1710 is not working what should I do ?

-question by usha

[jopak134]

sometimes dust can go inside the connectors try cleaning it first and check if the problem persist.

as of the fan spinning wildly, sometimes the powersupply will overload your fan during startup but this will not destroy it because only during the startup. if it is spinning wildly without stopping then look at your bios there is an option there.

no signal monitor, try cleaning it first if it still happens they try looking at the connectors see if some are crooked or to deep.

usually virus only affects your os files and such but not your motherboard. but there are some motherboard virus out there but usually pretty avoidable because some are preloaded with their own antivirus.

This has been speculated quite a bit recently. You can open up your computer's case and use a can of compressed air (search on amazon) to blow sideways on it to dislodge the dust (believe me, loads of dust gets clogged in the air vent, so it needs to work harder to continue)...

Try it; it really does work!

Else, take your computer's case off, and use a cloth to clean inside it... Do not use a vaccum cleaner!!!, this creates static and practically frys the computer's memory - so be careful!

[eukristian]

The best thing should be replacing the fans with new ones . Or at least only the ones that are not working properly .
About the screen signal , this is generally a video card problem , or a monitor problem . Any chances that you hit the video card during the cleanup ?

Asking again, sorry.Problems With My Computer FanHello. My PC has been running slow. I hear the fan going fast on the left side of the thing.It makes great difficulty when typing. The keys just stall, but after three minutes the letters that I typed out appear on the screen like magic.Do you know what the problem is? I just bought an expensive virus buster, and then installed it last night. It is still running slow.Thanks,James-question by James

Hi!

I think you've got the concept of cleaning the computer all wrong - you do not use a cloth to clean it. That creates static! Instead, you can use a vacuum cleaner (take the brush off and simply use it blow or suck up all the dust).

Computer wont startProblems With My Computer Fan

If your pc wont start after cleaning it, then usually you have created a static electricity inside it. To remove this disconnect all cables etc, from the back of your pc, hold down the power button with all cables disconnected and that should discharge any static electricity built up. I know it sounds stupid but it works I promise.

Problems With My Computer FanProblems With My Computer Fan

 I realize that this an old thread but..

Your CPU and/or case fans should normally spin up at full speed and slow down after POST. If they stay at full speed all the time:

The CPU is over heating - clean the thermal paste off the CPU and heat-sink. Re-seat the CPU and apply new thermal paste before putting the heat-sink/fan back on.

or 

The PSU is bad. Find someone that can test it for you and verify that.

or

The worst case scenario.  The motherboard and/or CPU is fried and need to be swapped out with new ones.

 

Another possibility is that the motherboard is grounding out on the case somewhere but this uncommon unless the computer was built by a novice.

One last possibility is that your graphics card is so shot that its causing your system to overheat. This would cause graphical issues during POST. (Weird colored blocks on the screen before windows boots up)
