So hi.
I bought a XFX Pro 550w PSU about 5/6 months ago after my old one broke, and I got it replaced because I didn't have the equipment to test whether it really was the PSU or if it was another component, but the PC repairman I got to replace it put in a EZcool 650w, which as you can tell from the name, was terrible. So I had to buy a XFX one to replace that (sigh).
But, point being, for the first few months I didn't notice any load noise or anything, everything was fine, but then a little while later I upgraded my CPU from a Phenom x2 550 BE to a FX 6300, and I changed the motherboard from an old shitty budget Gigabyte one (that was put in by the same guy a few years before....) to a ASUS M5A97 LE, and I changed the CPU cooler from an Arctic cooling freezer 7 to a CM hyper 212 evo, and replaced a generic case fan with a Corsair one.
Before this upgrade I didn't notice any loud noise from the PSU, it might have been less noticeable because the old fan & CPU cooler were a lot more noisy, but I doubt it, now the PSU fan is still very quiet when idle, but when I play a game it spins up much faster (probably going from about 600rpm to 1200rpm or so, and even though this still isn't that fast the fan makes a ton of noise, and my PC goes from fairly quiet to doing an impression of a quietish vacuum cleaner.
Fun.
Anybody got any ideas why this happens now, after upgrading my CPU? Surely the CPU doesn't require all that much more power over the old one, and why would it cause the fan to become so much noisier? Is this normal for XFX PSUs (even though it was fine before the upgrade), or has my one probably developed a problem? It's still under warranty so I can probably return it, because this noise really is pretty bad. It's not too noticeable when wearing headphones, but it's still there in the background.
