Hi there,
I recently got a desktop pc for 2d and 3d graphic mainly.
(GA z87-d3hp, i7 4700k, 2x 16gb kingston hyperx, gigabyte geforce gtx770...)
It all works great, except a ridiculously annoying noise.
Best part is that this noise is not continous, worst part is that is there only when I'm on the softwares I need the most there.
Whenever I am on 3ds Max the noise starts, if I move out to anything else like an explorer window (without closing 3dsmax) the noise stops.
Or also.. whenever I'm on Solidworks and I am rotating something the noise is there until I am done with the rotation.

I've been trying to locate where it should be coming from, seems to be from somewhere close to the power supply or the lower part of the mb.

Any idea or someone who had a similar experience??

If it's a high-pitched noise, that is common among PSUs. All PSUs emit a frequency depending on load, and sometimes that noise becomes audible. My PC Power and Cooling makes a high-pitched noise only when I run the Windows Experience Index but not in any of my games. You might want to make sure your PSU is compatible with your motherboard chipset though.

You should start with some monitoring programs for your gpu and cpu. Sounds like your noise comes about when your using programs that require your hardware to ramp up a bit, taxing the power supply more and pushing more through the motherboard. Could also be a buzz from a fan housing if your fans are set to spin up and down. If it's not a fan or any other moving part then some trial and error is going to be required, starting with swapping power supplies.

No.
Start by identifying the noise origin. Use an empty paper towel cardboard tube to your ear and point the other end around your PC until you can accuratley ID the source of the noise and then start from there. Check PSU fans, CPU cooler, GPU cooler and other sources of moving parts within your rig.

Also, sometimes loose hard drive screws or hard drives can rattle the drive carriage creating a low frequency buzz. Check all 4 mount screws on HDD and optical drives.

can you describe what it sounds like?

When the PC is loaded up, typically the fans will increase, particularly on the graphics card, which can be a whooshing air noise, grinding noise or high pitched noise, or you can get coil whine from the inductors which can vary from high to low pitched buzzing.

Thanks everyone for the help!

I am trying to locate where the noise is exactly coming from but without luck. Something I can say almost for sure is that might not be any fan, gpu or cpu or case itself (cougar evolution).

The noise is like an high frequency vibration which is always on the same pitch.. not more or less acute, just on or off. Like is switching (alt+tab) in and out of 3ds max would be the switch of this on/off noise.

This might be getting somewhere.. switching to "power saver" plan in power options reduce the noise by half.. let's say.

I never heard of it, but looking around seems very much what I have. So mainly, couple of suggestions guys:
-is that all because of the video card or not necessarily ?
-is there some kind of warranty/replacement I could expect at this point?? (pc is just 1month old..)

hmm, it doesn't sound like typical coil whine that I've heard, but as it's such a quick transition on and off, that's all I can think of. Unfortunately, there's not much you can do apart from try a different PSU or GPU. I've had various GPUs and one Zotac 670 was terrible for various difference coil whine noises all the time, but others have been silent, unless heavily o/c'd.

To find the source, perhaps try a cardboard tube to your ear and move it between the PSU and GPU to localise the source.

I believe most manufacturers will say the whine is normal and not a fault, but it is an indication that lower quality components were used and also for a manufacturer to release a consumer product that makes an annoying noise is also an indication of cost over quality. (I am an electronics designer/manufacturer).

Probably won't help much at all.

You could try using a different Power plug(rail) to your GPU from your PSU and see if that lifts some load off the coil.(trying to evenly distribute your power load)

I've encounter coil whines before with PSU, it's usually a cheap model or they're about to go out. Changing a PSU usually fixes the problem.
Remove the video card and use onboard video, test to see if there is still coil whine.
What power supply do you have?

This noise I have seems to occasionally react when I'm dragging with the mouse is those softwares. Turning power management off doesn't change a thing, but switching to Power Saver profile in the power options does reduce a good amount of noise.
