Hello, i brought a Asus P8H77-V LE Z77 and have fitted it into my HAF 912 Plus case, the case comes with a megaflow 200mm red LED fan and a normal 120mm fan at the back, with an slow for another 200mm LED at the top and another 120/140mm fan on the side. Both fans that come with the case are 3 pin, and i have read online that when plugged into the motherboard a 3pin fan can be controlled by the motherboard depending on tempretures and load, which is exactly what i want, for it to speed up and down when it needs to . but how would i do this with 4 3pin fans?? i have seen some 3pin splitters, but the only ones i have seen are ones that come directly off a molex connector and offer full speed which is not what i want, or are advising to buy a fan controller, and i dont see a point of trying to play a game while having to turn the fans up every time, i want each 3pin fan to be powered by a moulex and to be controlled (speed wise by the motherboard) i have heard that the 3rd pin sends a signal from the fan to the mb to tell it what speed its at, but then surely it uses the first two + and - pins to control it, surely you cannot split this without reducing voltage, so really what to do. i want both to be powered at the speed the motherboard powers them, and be able to add 2 more fans without changing the set up, note im guessing that the other 2 i buy will be 3 pin.
i had found this, http://www.pcworld.co.uk/gbuk/dynamode-fan-power-splitter-cable-with-cpu-sync-07843283-pdt.html but i want to connect it to 4 fans, and because its for 4pin only the 3rd and 4th pin are connected to the motherboard, and in my case because i have a 3pin header, only the sense pin will be connected, which means the motherboard will only recive signal and do nothing else, a bit pointless ?
overall i want all 4 fans to be auto controlled by the motherboard, via the 3pin header, note i have lots of molex connectors free but i dont want them at full speed as the PC is meant to be silent.
