Is there a way to determine exactly where vibration in a pc is coming from?

This started yesterday and its bugging me. I have tried putting my finger onto the fans to stop them spinning but still the rattle/vibration is happening.

Im thinking its either a hard drive I recently fitted or the water pump.

So I am going to remove power from the hard drive and see if it goes away, but on the off chance its not creating the noise is there a good way of finding where its coming from other than sticking my head in the case? :D
 
try putting a little pressure on the GPU.( if not watercooled)

those sapphire cads are very long. i have the same annoying vibration with my 290 tri-x.

1 nicely placed cable tie to support the end has eliminated it.
 
I think it might be the pump, especially if you recently fitted it.
I have a D5 on Bay res and it sometimes does this rattling sound (fitted it this week).
Happens if you didn't clear all the small bubbles.
 
Did not think about the graphics card to be honest, and the pump was not noisy to begin with its just the way I had to move the tower to be able to put the hard drive in might have moved something.

But I also had to take the graphics card out anway to get to the sata ports.

So its either:

- Hard drive
- Water pump
- Graphics card

Will have a look a bit later see if I can find it. Its so annoying as its a new build, it was virtually silent to begin with but as I have discovered any slight movement in the case can bring these annoying sounds.

Cheers all
 
Ok now its just taking the **** :mad:

I removed power to the hard drive I thought was vibrating, noise persists.

I lifted the bay pump out slightly and put it back in.

Tried lifting the graphics card up at the end very gently, noise still there. Tried turning the fans on the card as low as 25% noise still there.

Removed and left off both side panels of the case, noise still there.

Its just annoying, It sounds like a humming/buzzing sound with the rattling that follows and I cannot determine where its coming from :mad:
 
I think Bart Hunt could be right with it been the pump. The vibration seems to be resonating from the dual bay slot where the pump/reservoir sits and its basically rattling nearly all the chassis.

With the PC still on I moved it gently out the front of the tower a couple of inch away from the case and the vibraton virtually went away. Having put it back in it has calmed down a little but that could be due to heat outside going away.

Anyway seeing as it looks like its 95% the pump to blame for the noise, is there anything I can do to dampen out the noise, like vibration strips or something? Thing is the pump is so tight with only a couple of mm clearance either side so not sure what and if would fit in there.

Any ideas would be appreciated cheers :)
 
So no one has any suggestions?

I am almost certain now it is either the pump or the radiator as I tried going into the bios for about a minute with the watercooling turned off (disconnected the molex) and the computer was virtually silent.

Reconnected it and the noise instantly back. I have turned it on with the pump in my hand outside the front of the case and the vibration is still there. I thought maybe the tubes were vibrating but it does not seem likely. So maybe the radiator or the fans at the top are doing this I really dont know.

The buzzing/vibration is doing my head in, I can even hear it through my headphones its that bad.

Please suggest some things to stop it...
 
you will need to get some rubber material to try and dampen the vibration hitting against the case (based on your description). However, as you have pointed out you may not have a lot of space to do it and you will have to try to prevent insulating it too.

Could you post a photo so that it may be easier to suggest something?

Well theres pictures from my project log I recently posted: http://forums.overclockers.co.uk/showthread.php?t=18603290

But if you need more I can try and get some done tomorrow in better light.
 
Just quickly, I am wondering if you could get some paper or card board bits to wedge and see if the vibrations subsides.

The next thing is, you need to try and remove the kinks in your hoses. Maybe make them shorter? If you have too many kinks it can sometimes produce chugging effect. You need it as smooth as possible. This prevent too much change in velocity of the fluid being pumped.

Could try some card wedged between :)

The thing with the tubing length I completely understand where your coming from as the shorter/tigher the loop the better, but I had to allow some slack because of where the pump/reservoir sits. If it was too short I would not be able to pull it a few inches away from the case to drain/refill coolant.

Actually you need to try and keep it from changing directions too much. any luck with wedging?

No luck :(

Might just have to live with it for now and if I get more time at some point might redo the loops and everything and add some tubing and a valve to the drain port.

From what I have read it is not uncommon for bay pumps to make noise so I may even consider moving it somewhere else.

Cheers anyway ;)
 
I found the problem, weeks later mind you! :D

Yesterday I decided to see if I could push my R9 280X Toxic a little more and raised the core from 1150 to 1165 and eventually 1200 in MSI Afterburner.

Had no problems with the overclock but then the noise came back (it magically went away kind of for a couple of weeks), so then I suddenly thought the noise might be because of the graphics card and Afterburner.

Did a little testing with the fan speeds and I found the source of the noise. Its the graphics card making like a rattling/vibrating noise. I usually manually set the fan to about 45-50%, so when testing I took it down to about 25% and the noise went, put it to a 100% and the noise briefly comes back for a second before dissapearing. Keeping it at 45-50% brings the noise back occasionally.

So to sum it, the noise is from the graphics card! So tomorrow I might take a look and see if the fan shroud or something needs tightening up a bit. Having searched on what I discovered it seems not uncommon for these cards to have a rattling fan noise.
