Fan with no molex?

[twgamerbuilder]

I bought a few fans off of new egg and they have no molex connectors...how am I supposed to power them, there are only 4 pin cables attached to the fans

Most fans come with a 3 pin or 4 pin connection (4 pin is for PWM) and can be directly connected to the motherboard via a fan header:

Depending on your board you can have one extra fan header, beyond the CPU fan header or more (I have seen 7 before).

If you are not comfortable with that you can get a fan header to molex adapter:

Turns a fan into one that can connect via Molex instead of the fan header.

Hello... Do you plan to connect them to the PS in the first place? You will need just a TWO wire fan then with a molex connector.... a PWM 4 Wire fan will not work/connect this way.

My motherboard only has no other 3 pins but the one for the backside fan. are there splitters for 3pin ports that can go up to like 6? Plus, doesnt a fan need a molex cable to be powered? because these fans i bought have no molex connectors. Does that mean that the 3 pin will power it?

The 3 pin header is designed just for fans and provides enough power to power up to two fans. If you don't have enough headers then you would be best off getting the header to molex.

ok i will get that adapter, but i have a total of 3 other fans i want to put in this pc so do they make that splitter into multiple molex cables. Im having trouble finding one online.

I just realized that this is like the opposite of what i need because since the fans have no molex connections I would need a 4 pin splitter that splits into more 4 pins. Lol

Would something like this work?

If you connect it to a molex to fan header yes it should be fine. But I don't think it would work off of a fan header on the board. Most headers can push out enough power for two fans, more than two might meant he fans would run at a lower speed or not at all.
