From what I've read online it seems to be coil whine, and not the fan. But normally I'm all for voiding warranties.

I wish I could afford to splurge that much! Holy hell, that would be about half the price of my whole rig.

Well here's another idea i came across when i looked up coil whine.
Quote:
One way to fix coil whining is to use a hot glue gun and glue the loops together. Paraffin works better, is less likely to damage any parts and is easier to remove than hot glue. Mfgr's use paraffin but most hobbyists don't have it in their toolbox. I've used hi-voltage putty - a bit of a waste to be sure - but I had it in my toolbox.

Yeaaaah, that sounds right up my alley. Dangerous, risky, possibly lethal and all to solve a pretty minor problem. I might just have to give that a try.

The CX430 is a 380W, but the CX500 and CX600 are reasonably rated, though on the short side of mid-range.
Thanks for the update Phaedrus!

You're welcome! There are many well known brands that don't make their own PSU's, they are just rebadged or tweaked designs from other manufacturers. Just like LCD monitors, there are only a few manufacturers of the LCD panels themselves. LG, Samsung and Sony make their own panels, the other brands either buy from them or from some unknown factory with a weird name (which doesn't mean the panels are weird though LOL).

Going for 80 Plus in these days is the minimum really. It's becoming mainstream. Anything lower will just be using lower grade components. It's not really worth it, considering a good PSU will last for years, reduce your power bill, and protect your components.

As to recommendations, the Seasonic I mentioned earlier is excellent - it's 80 Plus Bronze, and can even handle a more powerful GPU, like a Radeon HD6850. If you need more power for future upgrades, it mainly depends on the GPU you want to upgrade to, and if you want to do some overclocking to the CPU and/or to the GPU. Let me know if you have an idea for future upgrades and I can tell you what PSU to recommend.

A nice fan would add up the cost of the PSU. Considering he would be losing the warranty in the process, I really don't think it's worth the hassle.

True, but he doesn't need a 1200w PSU LOLOLOL

He will be fine with a good 430w PSU. If he wants to upgrade the GPU later to something much better, like a GTX560 ti, or a GTX570, or a Radeon HD6950 or 6970, then it's necessary a good 650w. 1200w is for dual , tri, or quad cards setups in SLI or Crossfire.

If you eventually give it a try, you'll have to carefully check which one of the coils is responsible. No need to go putting glue in all of them. And when you do put glue in one of them, don't put too much, as the coil also has to cool, and too much glue is detrimental to that. You'll see that the coils generally only have glue in one or two places, only as much as necessary to stop the whine, and to let them cool.

Sometimes the glue doesn't stick very well or is put in slightly the wrong place (or not enough in the right place), and hence the coil noise from the copper vibrating.
