Loud fan noise on desktop pc


Could be the case fan or the CPU fan. Open the case and determine which fan is noisy by unplugging them one at a time. Replace the bad fan with a new one and you are good.

I have a Dell inspiron 1525...I have found that now, after a year and half the fan has become loud and noise. So noise, I wake up in the middle of the night, hearing my computer cooling b/c the fan is so...


you need to buy a new fan, your fan is about to give up the ghost. if you let the fan die while the pc is running, it might burn out the cpu.

fans are very cheap, like a few dollars, and do not always last forever.

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.

Hi, my compaq CQ50-115NR used to make great fan noise...now, nothing and it gets hotter and hotter...what should I do?


Have the fan replaced.

The 'great fan noise' you heard was the fan's bearings.
The looser the fan bearings became, the more the fan tilted, allowing the center hub of the fan to rub against the bearing base.

A laptop has a poor cooling system. All of the hardware components, are crammed into one tiny box. Air is the only cooling medium to keep these components cool.

The Processor, and the graphics chip are the two components that give off the most heat.
When a Processor becomes too hot, it turns off.
(BIOS turns it off)
This is a Fail Safe feature built-in, to keep the processor from burning up.

I would advise not using the laptop until this has been corrected.
Is the laptop still under warranty?

yes the fan can be changed before that your noise making fan can be fixed only you have to do is that unscrew the fan first take small brush clean the fan leafs and blow some air from your mouth to the bearings and motor part put a few drops of oil or 2-3 drops of oil in side bearings and slowly rotate your fan with your fingre to and fro so the oil can reached to the bearings and it will get lubricated wait for five mintues and fix the fan back in position and you can use it ot need to add more oil to it again add 2-3 drops thats all once the fan is lubricated it will not make any sound in the future this is applicable to all cooling fan it is must that once in a year you should lubriacte the fans for better perfomance and it will get more life too.....

Often you can blow the dust out of the fans and it will help. In your case the bearings have most likely dried up on a fan. First blow the dust out of all the fans. To find the offending fan you will have to block the blades with something. Once the fan is found you can either replace it with a fan of the same size or re-oil the bearings. To re-oil, carefully peal away the label on the fan. There might be a plastic plug over the bearing, carefully remove it. Drop a few drops of 4-in-1 oil or sewing machine oil into the bearing. Stick the label back on and put the fan back into the system. It should be much quieter now.
