Loud fans, can't trace it to a certain fan.

Is there not a thread somewhere on here that mentions a bent pin on the fan header causing the fan to run at full speed all the time? Might be worth a look.

Ok! Finally, I found the source of the noise. It's the three frontal fans that together make this rattling sound. I had to spread my fingers a bit awkwardly to stop them three at the same time and it was perfect, nearly silent, so definitely nothing really that internal/core. What could I do to get rid of this problem permanently?

IMO it really depends on what is causing the rattle:
If it's the fan blades/bearings rattling inside the fan frame, then replacing the fan with better ones is likely the easiest option, ideally with some sort of vibration dampening (ie rubber in corners).

If it's the fan rattling/vibrating in the case, check the screws are tight and/or get some silicone/rubber fan mounts/gaskets to try and stop the sound transferring... or replace the fans with some new ones which have rubber mounting.

EDIT: Is it actually rattling or is just 'loud' because it's spinning at full speed, if it's loud due to speed custom fan profiles based on temps might be an option too

I would say it's the first option: If it's the fan blades/bearings rattling inside the fan frame, then replacing the fan with better ones is likely the easiest option, ideally with some sort of vibration dampening (ie rubber in corners). It doesn't look as if the frames were loose or something, it's barely vibrating, I think it's the blades as they spin.

Would you have any recommendations with this vibration dampening (rubber in corners) and RGB? really not familiar with buying fans. 120 mm.

I can't really because I don't go with rgb fans in my builds, although my corsair fans (I've switched to bequiet now) weren't bad and they do do some rgb options. IIRC you do need to make sure the rgb connectors match your setup though.

I'm sure others will know more than me on this though.

What's the fan orientation? I tried e-loops on mine on the bottom (horizontal) and they were incredibly noisy. Vertically mounted, they were inaudible.
