trying to find the source of an annoying whine

[grind]

Hello people, today I woke up from my first day of vacation nap with my computer making a very annoying whine.. I quickly turned it off and on again because why not, at that point I still had no idea and didn't want to open the pc.

 

When it restarted it was ok and after some time the whine was there again. I now decided to open it and try to hear where it was coming from.. At first I thought it was my watercooler, but still unsure.

 

after fiddling with it for a bit, moving cables back and forth, unplugging the fans (restarting between one thing and another) to see if I could find the source, I still had no idea. One thing I learned with this is that the noise sometimes comes and go.

 

Then I opened up the computer and took out the radiator. PC crashed a few times on me and then stopped booting, I took out some stuff and let in just the basics, one stick of RAM and the boot drive, it didn't crash anymore, but once it has restarted for no reason.

 

Anyways now with the radiator outside I was able to hear it better and yeah, I think it's the source, but now the noise won't come back.. I think it has to do with the way the cables are when mounted.. Which is really annoying cause it's a very tight fit in my case and I can't just put it in another position..

 

To end this, I want to know if someone can help me identify the problem, i'd be glad if the watercooler is not it because it was bought overseas so I can't send them easily (don't even know if it's still covered by warranty, it's been more than 1 year). But still I'd really want to be able to fix this, having problems with my computer the exact same day I got my vacations is not looking too pretty for me..

I was going to post this but as I wrote the last paragraph the noise came again and I was able to record it, I'm uploading a youtube video to show it to you.. (also the noise went away, I'm starting to think it happens in cpu intensive tasks, I'll test it after posting..

possibly the bearings gone in one of the fans, i had it with my old GPU

Sounds like a bearing in the fan. Try stopping them with your fingers?

replace your fans

[grind]

I had stopped both of them when the noise was happening and it kept going but will check again as soon as it comes back.. Also I tested with a cpu intensive task and got nothing

[grind]

Yup, it was one of the fans, thank you guys a lot, at least I got one spare fan here to work while I try to get some better quality ones

 

wish I could like all of the posts, but unfortunately I can't lol, but still, thanks a lot

 

Also I'll take the chance to clean the pc more deeply than I usually do :v

 

edit: stupid me, I actually can like the posts k

that's not a whine, I would describe it as rattling noise - that's a bad fan
