The loudest fan in my case is a single NZXT 140mm that came with the Havik 140 CPU cooler. It runs at 1200RPM and produces a medium whirr sound---not silent, but not at all annoying. It's a very high quality sound for lack of a better term.

Around the rest of the case are a few Enermax T.B. Silence 140mm fans which run at low-speed (~600RPM) and are completely silent (<20dB).

When I ordered two Scythe Kamas for the Gelid Icy Vision VGA cooler I assumed they would become the loudest ones, even at lower speeds while on the desktop.

I was wrong--they're awesome.

The minimum speed I have set at 50% (~1400RPM) while on the desktop. At that setting they are totally inaudible over the medium-quiet NZXT fan on the CPU cooler.

Not until 60% speed (~1600RPM) can I hear them at all, and even then it's only by comparison to the lower setting.

Once they've reached 70% they will be begin to make the sound of airflow as they blow through the cooler. Completely tolerable.

I didn't mention the cooling? At that speed they keep a 165W Radeon 4870 at 50C under load (using the Gelid).

Even at 80-100% the sound still is not bad at all--not even close to the stock cooler and much better than the Gelid fans they replaced. If I ever need to run them at maximum they'll keep this card at 44C under load, quietly.
