Improving airflow (AIO/Fans etc)

[lsstefan]

Hello.

I just finished a new build, 7600k OC and it's cooled by a Arctic LiquidFreezer 240. The thing is my case can have 3 fans up front. I put the AIO as intake. Because I have only 4 Arctic fans(2 push 2 pull), I used 3 Cougar fans that are identical for push so that the front looks uniform. The Cougar fans push less air than Arctic, but they don't have such an annoying sound when pushed to max.

Now my concern comes from the fact that the CPU spikes to 75* when gaming. I don't know how long it stays there, got to find a way to see temps while inside the game, but I'm not comfy with them. Also, if I want a quieter case, the fans don't push that much air inside the case. The GPU looks ok at temps, but I'd rather have more air inside the case.

Now, I can buy another Arctic fan and put all 3 at front and rad goes standard setup, that MIGHT decrease temp a little, but the noise is annoying if the fans go to 1200 rpm(cougar at max-1200rpm- is super quiet). I made them stay at 1000 rpm until the CPU reaches 75.

Or I was thinking of using the standard setup for AIO with 4 Arctic fans behind the frontal "wall" and using the same Cougar fans in front. As in fan-fan-rad-fan. I know the airflow is fucked up, but live testing showed more air being pushed. 

I'm wondering if I use some sort of spacer between the first fan and the second to get a smoother airflow?

 

What's your take on this?

 

Thanks for the help.

why not just use high SP fans (corsair SP120) with a low fan curve. Personally i'd be very comfortable with CPU temps in the mid 70's (depending on what i was doing).

Because that would mean buying 3 SP120s to get a matching front and from what I've seen on retailers here, it will cost me as much as the case itself. I'd do it if it gets me 10 degrees lower, but for that money I'd rather delid and get more out of it, no?

The AIO should keep the CPU temps under wraps, like i said 75C isn't mind blowing, especially for a Skylake. What are your water temps when you see 75C?

I got Kaby. I don't know the water temps, don't have that sensor in the AIO I think, though you got me curious to find out if I do have one.

Yeah I guess I'm worrying for nothing. I might shuffle some fans around and see what's up, or just stay with the frontal panel off during summer since I don't A/C at home.

sorry, i know i said skylake. meant Kaby. i personally think you're chasing ghosts. 75* under load is perfectly acceptable.
