Question about fan splitter and cooling in general

hi guys i recently built my own pc and the temperatures were pretty ok but i thought id buy some fans because ill be getting some upgrades around christmas time so the extra cooling would be needed then.
i bought 2 fans only to find out my mobo only has 3 fan headers (cpu,2xsysfan)
now i tried running them off my power supplys molex but the noise was unbearable and as i understand sysfan would slow it down and only speed up when necessary?
would it be possible for me to use 2 fan splitters so i can install a total of 4 fans (2 that came with case 2 that i bought)
this is my system:
amd fx 6300
sapphire 7790 2gb oc
msi-G46
corsair CX500w
and corsair 200r case
so would using 2 fan splitters on both of the sysfan work fine?

typically, you do not want to operate more than two fans off of each motherboard header, so one splitter per header should be fine.

Another alternative would be to buy a fan controller that mounts in one of your exposed bays (if one is available and not in use). A fan controller can operate multiple fans and contol their speed/sound level.

I have just checked ebay for a fan controller and they are in the region of £10
i can get a splitter cable for like 2 so it would be 4 in total so im not sure what to do in this situation
also the corsair 200r doesnt have any place for the fan controller to go when in the hdd slot
also when connected to the sysfan header they will slow down and speed up instead of running maxed out constantly right?
edit: sorry the fan controller runs off molex doesnt it so i think i might aswell go for that i have spare molex anyway
i could get a fan controller that fits in the dvd drive slot and that would be brilliant

if you are saying you want to get two fan splitters (each connected to a different sysfan header) to operate 4 fans, then yes that will work. And as to your other question, yes, the four fan setup I described running off of your two sysfan headers would be controlled by the motherboard, meaning they would speed up/ slow down as determined by the motherboard sensors.

thank you very much i think i might go for the fan controller as it looks good and gives me control if they get too loud
if not i can allways go for the splitter

If you should decide to go the splitter route, you need to confirm with MSI that the fan headers are VOLTAGE controlled (3 pin) and not PWM (4 pin) controlled. A 3 pin fan CANNOT be speed controlled by a 4 pin PWM fan header. Likewise, with the fan controller, you need to match the 3 or 4 pin fans to the appropriate controller.
