I want to add more fans to my motherboard.

Hey, I have a H81M-E33 Motherboard, and it currently has a CPU fan installed and one intake. I would like to install more fans, so that the temps aren't as high. I am using the CORSAIR-01 Spectre case and it tells me that I can install two 140mm fans at the front, one 120mm at the back, and two 120mm at the top. However, I can only seem to find the 4 pin connector for the CPU fan. Here is the diagram -

That motherboard only has one sysfan header. Any additional case fans will have to be directly connected to the PSU and will run at full speed unless you opt for a fan controller.

So if I'm correct, I could just use a 4 pin fan connector hub, in which the molex cable goes into the power supply, and the other cable goes into the sys fan connection. I found one that has 8 4pin connectors and I'm planning on having 6 fans at full speed. (I have a 600 watt power supply, and I was going to SP120 corsair performance fans, is this enough power? Keep in mind i also have the GTX 970, an intel i7 4790, 16GB ram and a TX3 Evo cpu cooler)

I've never used a hub like that, so I can't comment on how well it would work, but it seems like it should do the job. I'm guessing you can't control the fans speed individually though. As long as you have a good quality PSU, 600 watts is plenty for your system. Your fans in total will be drawing about 15 watts at full speed.
