Well... Loud to me means it'* inefficient!
Time for a story about band camp. One time over there, a counselor-type person told me and some others that he at college shared a dorm room with a couple engineering majors. They figured out peak efficiency of each fan in each position throughout the room so that they used 4 large window fans to make the room really cold without AC.
I thought that was kind of cool, so I went to a room that I shared with a couple people and set up some fans to circulate air in through one window and out the other. I thought I hadn't done it right since there was no math involved, but the next morning I woke up with a cold, and it was freezing in the room. Just outside in the hallway though, it was nice and warm. So, shivering and with a stuffed nose, I walked to the counselor and told him the engineers were right. Then I sought antibiotics.
So, the moral of this story is that all you need is air flowing in and out. No need to get it at high speed. When you increase the speed of air flow, you actually may hit a wall unless you aim the flow so that it efficiently goes out. Otherwise, you will create either a vacuum to collect dust in the case or positive pressure to create hot spots. And noise either way.

Well I have more air going out than going in. My CPU stays around 35 C idle, 50C load. The case stays around 25 C. I think I got it right by only doing air cooling.

When I crank up both GTX285'* to 100% and put them under a load, it'* like a hair dryer blowing out the back of my case, this easily heats my room, and probably the rest of the upstairs if I let it go for a while. If it wasn't so expensive I'd get waterblocks for them, and the motherboard, add them to the loop I already have for the CPU, and it would be almost completely silent.

I've got both of mine running 702 core clock and 1584 shader clock, anything less that 100% and the main card will overheat, but having them in sli, smooshed right next to each other doesn't help either.

I have my CPU running 30C idle and 40 under load with fewer fans and less noise. It'* a Core 2 Q6600, the one with the 1.325 VID, which is the highest stock-rated voltage to come from Intel. And it'* not as noisy.

Well good for you. We can stop the e-***** contest now.
