why my cpu fan sound so loud?
116238
Your fan sounds so loud, because it is having to spin faster than it used to, in order to provide adequate cooling for the CPU.  Most CPU fan for the last 3-4 are 'variable-speed' fans. Which simply means that the fan can be spun at more that just one speed.  The fan controler sends variable votage to the fan to alter the rotation speed.\n\nSo, you need to ask yourself, why is CPU getting hotter....?\nAs the other posters pointed-out, one reason could be that dust build-up inside your case, and or the cpu fan/heat sink will reduce the heat disipation of the air flowing around inside your tower.  When dust covers something, it acts like a blanket, and convection heat loss is markedly reduced. If you can elevate the tower off of the ground by say 4 to 5 inches or more, you can dramatically reduce the amout of dust that the tower will suck into itself.\n\nA more common occurenc that I'VE personnaly run into in my shop of late, is that a tower with multiple fans...has had one fail.  Many towers I see have 2 case fans and the power supply fan (many p/s have 2!) So when one of them fails, a system that WAS barely heard, suddenly becomes noticable.\nThe more fans total there are, the less impactful the loss of just one would be.  \n\nHOPE THIS HELPS !

WHen you run the program, it is going through all the files in your whole computer, thats a lot of work. Your fan is probably heat controlled. WHen your CPU is working hard scanning, it is heating up so the fan comes on faster.

Ur fan is making Noice due to low grease ,and mayb its to old get it replaced it will cost abt 2USD(Ebay.com). or jus follow this.\n\nTurn of ur System.then Open the cabinet of ur system.Again turn on ur system and see which fan is making noice.When u get the rite fan jus agian turn ur system of remove the power cable attached with fan.there must be 2-4 screw attached to it,u just hav to unscrew them and take out the fan.\nThen remove the sticker(Brand name) and but some lubricant oil in it. rotate it 3-4 times.attached it again on ur MotherBoard or SMPS from where u hav taken it out.attach power cable.u r done!!\nIF problem still presist change the fan.\nFor more detail u can call me on +919893784025.

Its not the fan on your hard drive (it doesnt actually have one!).  It is possibly a dirty fan, and you may want to open the case up and clean the fans.  Just use a paintbrush (the big house painting kind) and you can easily wipe of all o the dust on the fans and heatsinks in the computer.  If it sounds like a loud BUZZing noise, then it is likely the bearings on the fan went out and it will need to be replaced.  If it has always been this loud, consider buying a more expensive "quiet" fan to replace it.

I believe the only parts of a pc which produce noise are the Power Supply fan and/or the hard drive.\nIf it's the fan, then it sounds like you need a new Power Supply (thankfully these aren't expensive) - however, if it's the hard drive that's making noise, it's a good sign that it's on it's way out - in which case, back up your data and replace it!

The extra fans will add to the noise.  So will the extra processors, and extra drives.\n\nPlus, servers are usually working a lot harder than your average workstation, so you will hear drives spinning up more often (and the fans running to compensate for them.

normal. but if your computer is in an encoles space on most sides, it could be overheating. just move it out into a more open area. the noise should die down a bit. but it is normal. the buzzing means that all of the grears are moving properly.

That could be a temperature issue. Make sure the air vents are clean and clear and that your fans are running.

Check your Cmos setup, if there is no setting for the fan, then i would not worry about it, it better to be cool than hot....It must be a Dell, just joking.....they have the most complaints....

just check the fan on processor is running and it is locked on the proses.bey be prrocesser geting heated up

Try this site:\nwww.almico.com/speedfan.php\nIt offers a software that can monitor and change your CPU's fan speed, to hopefully reduce noise. I don't know how well it works. It does say, "This program is aimed to the power user" (as in, it's not for basic computer users, since they might accidentally blow the thing up?), but from your questions, it seems like you are pretty knowledgeable. You might try it.

I had the same problem. Is was an electrical surge from my power source. Caused by  the fan motor in the processor. I had the motor replaced and it is back to normal.

Possibly your power supply fan.  Check to see if it has a lot of dust in it (at the back of your tower).  If it does, then you need to get some anti-static air spray and blow it out.  My Dell used to do that, but I always believed it was because something may have just been loose, and it was the case--all I had to do was tighten it up.  So, if you're computer savvy you could check out the innards to see if the IDE/SATAs are pluged in properly and if your processor fan is getting dusty--do the same to it, if it dusty.\n\nNow if it is more like a 'beep', then that means your computer has encountered an error.\n\nGood luck.

check if your CPU temprature is high.\nthe most common resualt of "CPU fan" problem is hanging or freezing.\ncheck if your CPU fan is working properly.\nthe next problem may be RAM.try to change RAM and test your system.

I run an AMD 64 but not an FX-62.  The idle temp is different depending on what OS and idle processes you run.  If you're finding that your cooling is inadequate, see if you can find a higher rpm cooling fan instead of (if this is your case) a prong heat sink.  If you want it to run quieter, relieve some of the load off your cpu (if you really want it quite and don't mind, underclock it).  Or, just stop some unneeded process via. msconfig in the 'run' bar.

Buy an aftermarket CPU fan.  These will be much quieter than the stock fan.  But you will have to buy one that fits on your processor socket, AM2, 939 and so on.  There will be different slots for AMD and Intel processors.  Once you know that you can buy a larger aftermarket fan/heatsink.  The other option is to go with liquid cooling but unless you REALLY know what you are doing, I don't recommend installing that yourself.  I just got liquid cooling for my processor and it is now super quiet.\n\n\nHere is a site with a few tips on how to make your PC quieter, http://www.endpcnoise.com/cgi-bin/e/buildaquietpc.html\nThere is another option to either buy sound insulation foam to put inside your computer case or sound insulation around the area where you keep the PC, if it is sitting on a shelf in a computer desk.\n\nAlso with the new fan/heatsink for the processor, you will want to consider Artic Silver thermal compound for better cooling and heat dissipation, though they may include some, I would use Artic Silver instead.

I think everyone is right about the fan.\nI have a fan that is making noises.\nIt doesn't do it all the time.\nI leave my pc on all the time (another debate)\nbut sometimes it growls at me and sometimes it is quiet.\nIt think eventually I will have to replace it because I don't know if you can oil it.\n\nThe first link I give you below shows how to replace your computer fan yourself very cheap.\nThen I add some links to help see what to buy later.\nGood Luck\nSteffy
