I've experienced some strange noisy sound in my laptop. I can't definitely tell it's from the fan, but I think so because hdd failure sounds are different.
The laptop is Dell latitude e6410, its hard disk and its cooling fan is next to each other so I can't distinguish where the sound comes from.
Here is the sound: https://youtu.be/3ud-5u_jJnk, sometimes it runs continuously.
It's not overheating. I've checked the temperature and it's around 50 - 60 celsius. It's maximum degree is around 100, so it is not the cause of heat.
I also tried disassembling the fan but it has two plastic weldings which I can't open. I tried using blower and using a brush to clean out dust but the sound continues.
Is it definitely the fan? then should I replace it or can I try something else?
Thank you in advance!
1Is it possible for you to disconnect the harddisk and power on the machine without the disk? – kasperd – 2018-12-02T22:39:35.907
Generally speaking, if your hard disk drive is making loud noises it hadn't made before, it's in the last stages of dying, and you'll notice other effects than just the noise (like, the laptop not booting). ;-) – DevSolar – 2018-12-03T09:43:37.590
3@kasperd loading a live disk off USB should be enough to have the PC running with no disk access - or even just enter the bios - though if it's only evident at higher fan RPMs it might not cause enough heating to produce the issue. a OS will allow the CPU (and thus fans) to be stressed. The HDD can also then be mounted and accessed, to see if that causes the sounds to begin. – Baldrickk – 2018-12-03T11:38:35.467
1100 degrees Celsius on a CPU is quite hot. While you're in there fixing/replacing the fan you should really consider getting new thermal past on the CPU and presumably GPU. – MonkeyZeus – 2018-12-03T16:03:08.577
1If the HD were wobbling, I would expect there to be a rather conspicuous symptom of, at best, files being corrupted, and at worst your computer going boom. – Acccumulation – 2018-12-03T22:42:49.577
@Acccumulation sometimes my hdd makes some clicking but I think it is not serious. – Gamal Othman – 2018-12-06T13:10:48.640
