I was considering the Sunbeam until I read Martin's review and that's when I had a flash-back to my smoking rig.
The 5 watts per channel isn't necessarily due to the heat output, but because the PWM feature fails to work at the lower voltages. This definitely seems to be the case with my Rheosmart 6. I have 1.05A on channel 2 (3 KM2 1700), and the fans don't start up at the same RPM as manual control. But channel 1 (0.35A) starts up at about the same RPM as manual.
I haven't had any issues with the heat produced, even at the lowest speed possible since I have a 900RPM 120mm fan exhausting it at all times.
Do you know if the Aquaero has trouble with the lower voltages when there is a large load (e.g. 20W)? Assuming it is adequately cooled of course.
I forgot to ask: Do the GT-2150's have any resonance issues like the GT-1850's?
