2 fans 1 header

[kotvid7]

Hi, i have a pc with an i3 4170 and an XFX R9 280x. I have a case that didnt come with fans, so k must mount them myself. The problem is I have only 1 fan header on the board.

1. What can I do (the molex to PSU isnt an option since i dont want it running 24/7)

2 Would 1 fan on either the side or the back be enough or do i need both?

3. Is it safe playing 1 - 2 hours of League of Legends a day without the case fans for about a week?

What is your motherboard?

Actually if u are only playing league daily 1 fan is fine. If 1 fan is plugged to the molex on the psu, it will only run when the pc is on

Im planning on having 4 fans, one plugged in the motherboard header, the others to a molex. What adapter dobyou recommend for the 3 3-pin fans to Molex?

You're looking for a 4pin molex to 3pin fan adapter:

although a 4-way fan splitter would probably be better:
