With that solid front panel case, you'd need high static pressure fans for proper airflow. Since case already comes with 1x 120mm rear exhaust fan, you can add 3x 140mm fans to it.

There's no need for front 2x 140mm fans to have LEDs since you can't see those. I'd put there 2x Corsair ML140 Pro non-LED fans,

And for the top exhaust, i'd put either the same non-LED Corsair ML140 Pro fan or one LED colored ML140 Pro (blue, red or white LED),

Corsair ML140 Pro fans are one of the best (if not the best) fans when it comes to the balance in airflow and static pressure. With them, you would have proper airflow in your case,

Here are the pros and cons of Corsair ML140 Pro fans:
Pros
* great airflow (20 - 97 CFM)
* great static pressure (0.2 - 3.0 mmH2O)
* great RPM range (400 - 2000 RPM)
* PWM control (4-pin fan)
* mag-lev bearing
* 4 color options (red, blue, white LED and non-LED version)

Mediocre
* noise output (16 - 37 dB(A))

Cons
* price

In my Skylake and Haswell builds, i also have Corsair ML Pro LED fans in use, both 120mm and 140mm with proper LED color to match the build theme. Full specs with pics in my sig.
