Well here you go guys. Got my Delta EFB1212VH-F00 fans and installed them on my Swiftech rad with some shrouds. I sacrificed a couple of old Antec Tri-Cools and cut the guts out to make these. These Deltas really rock. I am running them at 2200RPM using some Zalman fan controllers and the noise is a pleasing hum. At the full 3000 rpm I find them too loud for my tastes. They also look really cool with the 3 blade design. Don't get to see that much since this runs 24/7 So here are my results: 1200 RPM Max core 57C Prime95 small FFT's 2200 RPM Max core 52C Prime95 small FFT's 3000 RPM Max core 51C Prime95 small FFT's I was hitting over 60C with the original Swiftech fans at 60%. And these Deltas have a more pleasing sound. Kind of a powerful hum rather than an annoying whine Highly recommended for anyone with a WC setup.
