I have two of the black four pinned, and three of white 3 pinned. What's the best way to hook all these up to my PSU? Cheaper the better. Also the four pinned ones could likely use an extension as they're pretty short cabled...

Thanks for any help!

4 pin fans are generally PWM / 3 pin fans DC .... 4 pin MoBo headers OTOH can be either. You generally do not connect fans to a PSU but to the appropriate MoBo headers. need information...MoBo model, what the fans are for, PWM or DC ?

The 4 pin should be for CPU cooler and the Go to CPU / CPU _OPT headers....other go to chassis headers.

My Mobo is a MSI x58m. The two 4 pinned are actually just two fans at the front of the case. I managed to get the 3 pinned ones hooked up my a fan controller adapter that the case came with.
