How much were those fans, if its not too much I'll need a new one to keep my case chilled when it gets hot by spring time.
I take that you live in USA. If so, you can order the NZXT AER RGB120 & HUE+ directly from NZXT's site and it costs $79.99,
For NZXT AER RGB120 fans, here's pcpp link: http://pcpartpicker.com/products/compare/w7RFf7,CDZ2FT/
You can go for single fan or buy 3-pack to get fans with cheaper price. Do note that when you only buy the fans, you still need HUE+ controller to control the LEDs in the fans. If you don't have HUE+ controller, you're best to buy the NZXT AER RGB120 & HUE+ set (includes HUE+ controller and 2x AER RGB120 fans).
Few words about HUE+ and AER RGB fans.
HUE+ needs 1x molex connector to power it and 1x internal USB 2.0 header to control LEDs. It has 2 channels and per channel, HUE+ supports either 4 LED strips (10 LEDs per strip) or 5 AER RGB fans.
AER RGB fans are 3-pin and to power them, you need to connect them to fan hub (as i did on my case) or to the MoBo fan header.
If you don't want to spend money on HUE+ then for alternative, you can go for Corsair ML120 Pro fans,
Those fans are the other ones you can see in my case.
Corsair ML series offer better performance while NZXT AER RGB fans offer better eyecandy.
As far as your Zalman CNPS5X Performa goes, you've mounted it the wrong way.
You may think that it's easier for you but in reality, it makes things worse. Since your CPU cooler takes the air in from the back of the case, you'll get far more dust into your system since the area of the back end of the PC is usually dustier than the front area of the PC.
Mount your CPU cooler other way, so that the fan is facing ODD bay. Also install rear 120mm exhaust fan and you'll get lower CPU temps than you currently get.
Unless your using the fan to "pull" which is less effective than having the fan "push".
His fan is in push mode since the CNPS5X logo can be seen on the center of the fan (that indicates the font of the fan).
