The Zalman Fanmate 2 is only designed to power a total of 6W. The Yate Loon D12-SM (the 1650RPM model) is rated at 0.3A, which at 12V is equal to about 6.3W. Running 2 of them on the same power line is really going over the limit of the Fanmate 2.

The better quality fan controllers will go all the way up to 12v without dropping the voltage, like my Lamptron for example.

I'm not sure if it's all the way up to 12v but it's either at 12v or very close. I have ridiculously loud and fast fans and even with sight variations in speed they have a noticeable pitch change. They sound identical when plugged directly into my PSU 12v rail and 100% on my fan controller. I'll grab my DMM when I get home tonight and measure it for you to be sure though.

I just tested it and it does indeed output 12v! The reading at 100% is 12.08v according to my DMM, my direct power supply rail reads 12.16v so only an 80mV drop seems pretty good with it equaling 99.3% power output.

I'm using the Lamptron FC Touch, I'll do a test on my old Rheobus if I can find it and see how it does with the voltage drop in terms of a cheaper but still decent quality FC.
