Matt, are you sure you didn't replace the fans with the wrong type?
Not sure that's possible. The PM fans are indeed both RPM and PWM controlled, but there don't seem to be differences between PMac models in this regard. As in: an RPM controlled fan will be RPM controlled in all models.
As for Noctua fans: matt, are you able to get Noctua fans built FOR the PMac? The connectors on PowerMac fans may look standard, but the voltages are NOT. You WILL burn your PMac if you mess this up.
Am I sure? No not one bit:). These don't seem to be built for mac...
I was going to get a NF-A9 PWM that run at 2000RPM, from the graph on the website it is the best all around for air movement and pressure, that I didn't even know there was a difference before I went to the site.
I was going to wire them for max speed and just hope for the best. I suppose there has to be a way to get a reading and see if that is reasonable?
I did put one Nactua fan in as a test to replace the fan by the speaker. I wired it to run contstant. So far so good. This fan doesn't impact the cpus that much but was a test case...
