Thanks, just what I needed to know! So the CPU OPT header is better used for a push-pull configuration on a CPU cooler (although I don't even know if my CPU cooler supports that)? Do you think it would be good to use this kind of fan on the cooler or do you think it's way too loud and I would be better served with something quieter (since this fan has to be run at less than 50% to be bearable.) Sounds like using the CPU OPT header to run a case fan would not be a good idea since the CPU FAN usually runs at a higher voltage than the case fans on the Chassis header and the fans I am using are particularly loud and I want to keep them to as low a voltage as possible.
Do you by any chance know what the minimum speed is that I can set my fans to on each of these headers- for example, can I get them down to 50% or less? I would think the Chassis fan headers are more flexible on the minimum speeds while the "system" automatically controls the CPU FAN and the CPU OPT header and manual control over that is not possible or not a good idea? Another question, is the amount of maximum power draw allowed on each header 1A, and does the same apply to the CPU FAN and the CPU OPT headers or do they share 1A between them since the CPU OPT header is a slave to the CPU FAN header? Thanks!
