Loud Fan on my Laptop

Go buy a can of compressed air and blow out the fans and vents. That should get it running quiet again.

Sounds like the fan is going out. I would take it back to the store and swap it for a new one. Alternatively, if you decide to keep it you can try to put a drop of 3-in1 oil in the center of the fan to prolong and/or fix the noisy fan.

if your computer is still under warranty take it in if not you might have to buy a cooling dock or buy a fan and swap the old one in for anew one personally i would not do it my self if i didn't know haw to work it but take it in to a best buy and they will fix it for like twenty or thirty dollars

Hi:
Not sure of a user cause for the fan to run full speed, unless you are using the laptop in a high heat environment, or setting it on a bed or other area where it is not getting adequet cooling air. If it does it right away, when you turn it on , cold, then there might be a laptop hardware problem. If you leave your laptop on all the time, then you might be inducing the problem. I had a HP high performance laptop, that the fans would not turn on at all till it ran an hour or so, then they would stay on loud for 10 or 15 minutes, then shut off, then cycle.

Hi

Its normal for a laptop computer or a desktop computer to spin its fans at maximum speed during start up - its part of the power on self test.

If the fan is very loud like on this video the sound is very bad -


that would be a bad fan, constant bad noise. but if your fan only makes noise in start up, its normal.

your warranty should cover the replacement of the fan if its bad.

the gears for the revolving front panel is worn and slipping.

well if its not attached to the motherboard in any place, for example the heat sync, or the cpu, then you can remove the fan, any other place, you shouldnt replace it because the mother board sets the fan at a certain rpm, and which would sound loud with any fan. I know this because i replaced the fan on my sony computer, and on a generic motherboard, and it was quiet, but when i put it on my sony computer, it was loud, so if you want to replace your fan, i suggest liquid cooling, it is completely quiet, and keeps your cpu much cooler than a fan. Best of luck.

I would not recommend this. You could fry your cpu and then you would have no notebook. If you are going to open the notebook make sure there is nothing interfering with the fan. The fan can be replace. Take the fan out and try to replace it, if needed. Do not run the notebook without a fan.

usually loud fan noise in computers means that the fan you have got is too fast for you computer or too slow for your computer. go back to the place you got your fan from and ask them to check its compatibility with your computer.
otherwise try cleaning the fan or removing it and making the screws a little bit looser. might jusdt be rubbing
