There is nothing wrong with positive air pressure (more air flowing in than out). In fact, positive air pressure creates a low dust environment if fan filters are used at the intake fans.

IMO, only use the front two 140mm fans , bottom 1x 140mm fans, top 1x 120mm and 1x 140mm fans as intake. The only fan you should have as exhaust will be the back 140mm fan.

So you should have a total of 7 fans. (3 up top, 2 up front, 1 bottom, 1 at the back).

I am going to disagree with some of what has been stated, in that I think you should keep the internal HDD cage mounted fans. They (cages) are incredibly restrictive, and I have easily doubled my front intake airflow simply by using 'push-pull' fans like that.

Regarding the radiator, I am running a custom loop with two rads (420 top and 240 bottom, both P-P), and I have found that having the top radiator in exhaust (ALL rad fans must point the same direction!) is noticeably better than as intake. Furthermore, simply turning my rear fan from exhaust to intake allowed a further few degrees drop due to it feeding cool air directly to the top rad, as well as lowering VRM temps for my motherboard by a fair bit.
I would suggest trying to have the CLC rad as an exhaust, leaving all other fans as is except the rear exhaust switched to intake and see if it helps.

Oh, make sure you have all rad fans blowing the same direction (2 in and 2 out of the rad), and I would remove the other top fan in your case and instead just mount the rad fans exactly how they should be (your pic has them offset quite a bit).

yeah i fixed my rad fans now. 4 fans pulling and pushing in and out of rad inside the case and also a bigger fan on top of all to also assist the effort. maybe i will give it a shot next time i have a big upgrade because the last time caused my to heat up my CPU at 98 C and i don't really feel comfortable with that again without having a problem.

I really agree with all you said and i will try it and let you know.

So i just turn all CASE fans as intake and only the 4 rad fans as exhaust?

More air coming in than out is good. This prevent air ducking in trough gaps carrying dust and stuff.
