i thought it was my fans i turned off case fans (not HSF) and it was still there, so i turned on fans to 100% and hsf off for like 5 sec and still there... so...

its def coil whine i think

Yeah, could try swapping PSU's and GPU's since those are the main ones that usually have coil whine. If it's still there then its most definitely your motherboard. And what I did ( I have coil whine when I fold) is I opened my case, got really close to it and covered one ear and see what side it was coming from.

I don't have any other hardware to swap.

I tried to pinpoint the location using a rolled up piece of paper (ghetto yee lol) and it seems to be coming from the mobo around the area where the CPU and memory are located.

Also, upon investigating the PSU, it appears to be making whirring sounds. Is this normal? I know there's a fan but are PSU supposed to be silent or should I look into that as well?

Hmm...that makes me believe the coil whine is mostly likely coming from the VRM's of the motherboard. And whirring sound as in moving air? Yes that is normal as almost all PSU have fans to cool their components. And I think we have the same PSU and I have to say that it's not completely silent but it should be virtually silent since the fan is not speeding up because it's hot. Corsair PSU's are extremely silent until on near full load. If you still your box with you, you can a graph a what wattage and at what temperature the fan speeds up on.

It could be the PSU wires. That's one reason I chose my Silverstone.

To reduce electrical whine/buzz associated with high performance graphics card’s dynamic loading changes, 2200uF capacitors are attached to PCI-E connectors. This design also helps to maintain better voltage stability and improve ripple & noise performance.

what's VRM?

i turned on prime 95 and the coil whine just stops! then all I hear are my fans going from 50% to 100% and its a freaking wind tunnel lol.

when i turn off prime 95 the whine comes back =/

*** lol

The VRMs are the small cubes sticking out of your motherboard. I have attached a picture circling some of the VRMs on your MOBO using my awesome paint skills.

You could try clear nail polish on the VRMs and capacitors, it worked for my GTX 460.
Although you would probably have to dismount your motherboards heatsinks to get access to all the VRMs.

Try RMAing first.

I would HIGHLY discourage "insulating" your VRM's and caps with anything..your asking for problems.

As for the "whine" ...if it is not present under load, I would venture to say that nothing is wrong at all.

Hmmm try a CPU intensive program or a game and see if it stops then. This could most likely now be the VRM's (Voltage Regulator Module). A VRM is basically a voltage regulator for the CPU. When a CPU is idle, it's usually on a lower voltage to keep it running cooler. When on full load, the VRM's supply more power to the CPU to keep it running. You can locate them on a motherboard by looking for little black squares around the CPU.

I too have rail (or capacitor) whine frown.gif. I didn't rma since I sleeved the majority of my cables and I didn't want to go through the hassle of taking them off. But, so far, my power supply has been able to handle three oc 470, three 6950s unlocked, and hopefully three 580s 3gb (trying to sell since I'll be better off w/ 1.2kw). Thus, if it ain't broke why fix it? It is annoying btw rolleyes.gif
