I'm not sure I'd order the Delta fan to use the Low Noise Adapter as that fan is probably overkill just to use it at less than full capacity. I bought as I read about it in this thread and thought I'd rather live with a lot of noise and have my analog board last forever. Once I installed it though, it was clearly something that I couldn't live with even though I prioritize component life over noise. That being said, the Delta might have ended up sucking the components right off the analog board.
Nice fan indeed, but the problem with those translucent fan blades is that they usually don't last long.I am always surprised more people don’t mention these Nanoxia fans: http://nanoxia-world.com/en/products/fans/deep-silence/240/deep-silence-60-mm-2000-u/min?c=50
2000 RPM, 15.8 CFM, 12.1 dBA
So, more airflow and less noise than the Noctua at the 2400 RPM setting (allegedly). I’ve been running one in my maxed-out SE/30 for about 18 months now and it seems to keep things nice and cool. Though I always wonder if it’s really doing the job ...
