1 way to be sure plug wattmeter and read what you get from the wall. Sometimes even bios version can show different watts on screen. thats why you need measure it from the wall.
The watt meter (kill-a-watt) will give you the firm answer.
I think you will find the blower cards use a bit more power on the fan than regular 2x or 3x fan units. The blower is a much higher static pressure than the little prop fans.
Wow, bad assumption on my part that the two different card styles would report the same in software. Output from the wattmeter shows they are more or less the same from the wall (~880 watts for reference). So the 2x open fan units underreport more in software whereas the blowers were dead on per readings in SMOS.
Thanks for the help!
