Fans that I have :
2 AF120 quiet edition
2 SP120 quiet edition PWM,
1 SP120 High performance edition
Stock fans of my case which includes 2 generic fan and 1 LED fan
1 Generic Blue LED fan
Stock fan of H7 cryorig
ID cooling 12025 fan

My PC Specs :
Mobo : G1. Sniper Z5S
CPU : i3-4170
CPU Cooler : Cryorig H7
GPU : Asus Strix Gtx 750ti 2GB OC
RAM : 1x4GB HyperX Blu, 2x8GB Ripjaws DDR3
HDD : Toshiba 160GB and Seagate 500GB
SDD : Intel 520 Series 240GB
PSU : Zalman 700W 80+Silver
Case : Tecware Infinity



My questions are :
1. What fans will I use in pushing/pulling the air in my cpu cooler?

2. Will it make a difference if higher RPM was applied in the pushing of air rather than the pulling? or vise versa? or neutral?

3. Is it better to have a SP120 fan in the rear because of the blockage of another fan installed in the H7
or ignore that obstruction and use an AF120?

4. In the front of the case where the HDD case is located, shall I use a SP120 and AF120 on its top or 2 SP120? or 2 AF120?

(I can't install a fan on the top because my motherboard's capacitor is there.)

(Sorry for the long thread with too many questions in it.)

Thanks in advance to those who'll answer and notice my post!

Performance per fan drops dramatically at more than 1 fan. 2 is really the most you will ever need on the case. As lodders mentioned your i3 won't benefit much from that Cryorig cooler but if you plan on upgrading in the future then you got that covered at least.

If you want to utilize the most fans you can, positive air pressure is the cleanest route. Have more fans pushing air in than pulling out. Dust will collect on the fan filters and not on your components. Those 2 PWM fans should go on either side of your Cryorig cooler, one pushing the other pulling. You should have the 2 AF120s at the front of the case and the last SP can go either on the top or rear of the case. The last remaining fan will go wherever is left.

You may be surprised by this answer.... but
For an i3 processor, you need the intel stock cooler which you get for free.
For the rest of your system, you need one case fan, pulling air out of the back at the top.
more cooling than this will make no difference to the life or performance of your system. It will only increase noise and power consumption

1. Cryorig, while nice is not really necessary.
It will be quieter than the stock cooler which should be a reason to buy it. The fan will blow through the cooler and out the back of the case.

2. No matter really, but push is more effective than pull.

3. For the fan setup, put two 120mm fans in front as your only air intake.
When it is filtered, the air will exit someplace taking heat with it.
If all your intake air is in front and filtered, your case will stay cleaner.

At most, use a single 120mm fan at the rear to direct the airflow.
Do not use a strong exit fan or any other fans. Otherwise they will draw in unfiltered air from adjacent openings.


Lastly, do not obsess about fans. Your parts are not hot and need minimal cooling.

In fact the cooling setup I suggested would be satisfactory for a i5-6600k and a GTX1070.

Thank you sir. I didn't know that I must focus on upgrading my proc first before considering this case airflow. My bad. XD

thank you sir for that information. As you said, I'll just focus on upgrading my CPU first! thanks again!
