Jammoy :
Thanks for the advice.
The reason why I want many fans, is for a better air flow within the case. Also a sound card for better sound as I have a gaming headset. Also I prefer the one I have with is i5 4690k as it has better base clock speed than i5 4460.
There is a point where adding more fans give no improvements or can even disrupt airflow.
Motherboard now have decent sound chip. For gaming, you do not need one. If you are an audiophile, you are better off having a decent external USB DAC rather than a soundcard. That's assuming you got a decent high end headphone/headset.
