Hi all, newbbie here. I've just bought a GA-P55-UD3P mobo, which has the capability to measure/(control?) to system fans. The problem is that after a fast research (CFM/dBA...) I purchased today two Thermaltake Thunderblade A1926 (main cabinet 120mm), which, according to the specs, are quipied witha 4 Pin connector, which I assumed (wrongly) that was the four pins to the MoBo's SysFan's 1. My surprise was big when I saw that it is actually a PS molex connector!! and the "inteligent wiring" is just a 3 pin with only 1 wired to measure the RPM. I'm not sure (and MOBO manual is quite poor on this aspect) about the two power pins on the MOBOs output (fourth one is actually "reserved"). I assumed that only the CPU one is controlled via PWM, and for sysfans the speed control (if any...) is only done varying voltage. In any case, might I wire (using proper connectors, of course) the two other pins from MOBO to thefeeding one on the fan? Will the mobo decrease the speed decreasing the voltage: I assume that the "starter voltage" on specs means that needs at least 6V to operate, hence I guess that with any valkue between 6 and 12 the spped will vary. And if it is PWM, why a special fan is needed, if actually changing the pulse width I can actually decrease the average (that's not the word but I don't remember it :( ) value?
If anyone can help, I would appreciatte it.
Thanks in Advance
