Antec True Power PSU

I was wondering if using the fan only connectors is a good idea of not, it seems I get higher RPM out of the fan's when they are on default power conectors.

Your fan's shouldn't run any faster just because they are connected to the regular 4-pin Molex plugs. Just like the rest of your system, it will only draw as much power as it needs, unless you have a rheobus or baybus connected to it.

I think the fan-only connectors have the power supply control how fast the fans are moving. I've got 2 of my case fans on them.

If so, that would explain why your fans went faster on the regular power connectors than on the fan-only ones.
