Well, the huge fanless heatsink is sure attractive

Whoa, hey now, is that a rice burner I see over there?

Thanks for the excellent reply Chris! I think I will just "go for it" then, shall I? 8) I'd imagine with a 18cfm fan, there won't need to be very many holes considering how little air it pushes. It'll probably just come down to experimentation, covering up various amounts of the 92mm intake. Now to ...

Er, does this sound alright (sorry if it sounds like I'm being pushy, but I've got to get the stuff today or tomorrow to get it here in time)?

There must be some sort of fan control device in my PSU even if I didn't see one, for the whine of the fan certainly changes in amplitude depending on load. It could indeed be that the bearing is shot and exhibiting the exact behavior you mention. I have heard that a PWM circuit can also cause unnat...

Gah, you people are no help. I was thinking of something along the lines of a NMB 18CFM fan. Would this provide enough air for the task?

Ah! It seems the noise was coming from the 80mm fan in the PSU after all! :oops: :lol: Even though I saw no control circuit while poking around in the PSU, there obviously must be something affecting the fan speed during idle vs load. So...any good fan replacement choices? Besides the obvious Panafl...

I have already done a thorough search, and while finding useful threads on coil whine specifically, I did not find anything that would pertain to my current situation, namely, where would I apply the adhesive in the first place?

Well this is going nowhere. I was hoping that the contest would pull more people in and therefore relate to quicker responses, but I am going to have to do this soon, and still no conclusive answer on whether supergluing the yellow objects (transformers?) and the exposed coils will help anything. I ...

Well, is there any way to stop this noise, or at least mute it, by applying a hardening substance such as superglue to the transformers and external coils, et al (what other components might make noise)? And does it make sense for the whine to be present during idle periods, but not during full load...

Yes, this is exactly the same symptom I have, and I know it is not the hard drive because I have replaced it twice, now with a Maxtor FDB drive that is almost silent. I am almost positive it is the PSU. But how to cure it...

I won...












Nothing! Makes you real jealous doesn't it?

So there is no way to fix it except by replacing the capacitors?

I have an R31 that is MUCH cheaper (picked it up for $800 on IBM's eBay store) yet has the same nice build quality as their other notebooks. Only difference is the case is plastic instead of metal alloy and it's a tiny bit thicker/heavier. The fan rarely spins up unless I am watching a movie or some...

Yes, apparently my Antec (HEC OEM) PSU is exhibiting a very bad whine on idle, but not load :roll:. So I got myself a bottle of brush-on superglue, but I'm not sure which coils I should apply it to. http://tangent.ath.cx/tempstore/psu.jpg Are the coils with the black and yellow cores the proper ones...

How come that last post didn't bump the thread up?

Nope, no northbridge fan

OK, let me rephrase - At the CERTAIN ANGLE I am sitting at, the sound is louder than that of the WDBB. Compared to a WDBB in the same wooden box that my computer is in, it is louder in noise. However, if I move around the sound shifts from being a little bit quieter than the WD to where I am sitting...

So would plain old cynoacrylate superglue work to quiet the coils? And if I were to put a quieter 80mm fan in and remove the 92mm, would this have an effect on an already very whiny PSU? I certainly don't have a problem with regulator whine, as I know it happens with all such electrical devices. How...

Well, I rarely play games so I believe it to be quite safe for me. I did try running 3DMark for about an hour, and saw no artifacts, but there are no guarantees as to long term stability yet. Anybody know where I can get a temp monitoring utility so I can check out the temps without reaching in my c...

That's what I did with my Radeon 8500...running like a charm so far.

True, but this article seems to make the point that Deer has changed its ways and is making quite good power supplies now. Hence the reason to find out with this thread.

Well, if the whine is pretty surely the PSU, then I think I will go out and grab another for $20 that is supposedly very quiet. This is really not just a little whine though. It is quite loud and can be heard over all the other components in my semi-quiet system. It's high-pitched enough to drive me...

http://www.mikhailtech.com/articles/psu/l&c350/ While browsing around on the internet, I found this interesting power supply that is claimed to be very quiet. It also has shorter cables which could help tidy up cable clutter. The power caps are very large. One especial feature is that it seems to h...

Ah, I see now. Thanks a lot for the very useful replies. I will probably just end up cutting the RPM wire off. Now if I could just get rid of this annoying coil whine...

Wow, that thing looks pretty big, especially if it can accomodate a 92mm fan! However, the bolt-through mounting seems like a bit of a pain. Any word on how this cools compared to the AX-478?

OK, I get the picture now. So is this the sign that my PSU is dying and that I should get it replaced? Or is this simply an unavoidable phenomena of all PSUs? Should I just leave Prime95 running all the time to keep the system at full load?

But why would the whine only be present under lighter load instead of heavier load?

I'm having a very strange problem with my computer. Whenever the computer is idle there is a slight whining sound emanating from it that gets quite bothersome after a while. However, if I use a program such as Prime95 to set CPU load up to max and raise the temperature up, the whining sound miraculo...
