High-pitched noise

Postposted on Wed Mar 21, 2012 4:26 am

Hello again,

I'm having problems with my build, just like OP in this other thread, but I can't decide whether the high pitch noise is coming from my Fortron Hexa 500W PSU or MSI GTX460 Fan OC or both. Please note that it's impossible for me to determine the direction and source of the noise, sometimes it sounds like it coming from the psu and sometimes like it's coming from my graphics card. Also, I've checked my speakers and disconnected them just to make sure...

The symptoms are as follows:

- Almost imperceptible high pitch noise when in idle. Disappears totally if I move the mouse or when changing desktop resolution. Note that the high pitch sound goes away just for a second, right when the screen goes dark, after that it's all back, no matter the screen resolution

- Sometimes a very silent crackle can be heard if the side panel mounted 80 mm Nexus RealSilent fan is connected directly to the PSU via molex

- Very loud, high pitch noise and crackle when starting up games, but only at startup intros (i.e. EA Games intro) and when pausing game and accessing in-game menus. The weird part is that this high pitch noise and crackle combo only happens in Kingdoms of Amalur - The Reckoning and Alan Wake. Other games like CoD series, BF series are not affected at all, but Syndicate and Mass Effect 3 are partially affected and only a mild, continuous crackle can be heard.

- The weirdest part of them all is that while playing games under full load or watching movies, both my PSU and GFX card don't make a noise (except for the fan noise)

PS: I bought both the PSU and th GFX last summer and they're still under warranty for the next 27 months

Here is a way to test it out: see if the nVidia drivers have any kind of temperature and/or fan controls for that card. Monitor that to see if there is a correlation between the high-pitched noises and temperature and/or fan RPM spikes. If there are no changes to those, suspect the power supply.

Personally, my money is on that GTX 460 OC.

Well, no temperature or fan rpm rise during any game's startup intro, it's the same as before. However, when the game intros have finished loading, and I play the above mentioned games, I don't hear that high pitched noise, even with my speakers turned off. Fan RPM does rise after a few minutes into gameplay, but that's natural. I've heard people complaining about coil-whine when the gpu is under full load, but never in semi-idle state when intro videos start to play, or exiting a game to the main menu, or even idle on the desktop. Based on what you say, Riviera74, the conclusion is that my PSU is more or less busted.

Cards, PSU, and MB can all be source of coil whine.

Depending on your definition of "busted"

Parts with coil whine can continue to function for a very long time.
However if you can't stand the noise, then yeah, it will not repair itself. :wink:
