Case: Raidmax Hyperion https://www.google.com/search?q=rai...X&ved=0ahUKEwjipdyF6uzLAhVF8CYKHfDPCKQQsAQIJQ
Mild OC on AIO water cooled 6600k, and RAM. No GPU. Maybe a gpu down the road, and if need be, deal with other cooling options if/when that time comes.

For now, I'd like to go with redux throughout, unless someone has a better suggestion for a slightly pressurized flow while keeping it as quiet as possible. If at all, with 7 fans.

Would P14 - 1500 PWM be the replacement for this stock rad fan?
What about the CFM and static pressure differences?
http://noctua.at/en/nf-p14s-redux-1500-pwm
http://www.swiftech.com/Helix140-PWM.aspx

With 2x 140mm on top (one is rad) + 1x 120 rear all being exhaust,
and 4x120 intake (front/bottom),
what other 1x 140mm and 5x 120mm's would I get?

I won't need all the fans to keep it cool, I just don't want to see empty case fan grills in the main compartment.

How would I keep it relatively equalized with pressure? Perhaps 1 or 2 front 120 as PWM?

Using Fan Expert 3 ok?

Thinking these fans, when not used as PWM, can be set to much slower speeds, I'll just throw this out here and see what sticks:

Top 2x 140
P14s 1500 PWM = replacement for the rad Helix, and
P14s 1200 3pin to go next to it. Can't do push/pull.

Rear/front/bottom
NF-S12B -1200 3pin (5) 120's.

Or for the case fans there's 140mm - 900 rpm & 120mm - 700 rpm variants that are quieter, if that's enough air.

Are all your rads 140mm? The best extant 140mm fan is the Noctua NF-A14. NF-P14 is OK, but the A14 is quieter.

For 120mm fan, the Gentle Typhoon is best.

The only 120 Typhoon I found available is AP15 - 1850 rpm. Not the 13 or 14.

Just one. H140-X 140mm version of http://www.overclockers.com/swiftech-announces-h220x-release/
And it’s designed for push so I need to decide if I’m going to let it push into the case, or pull which may not be as effective because of pump obstruction and case fan layout. But, the 6600k should still run pretty cool with a mild(4ish) OC shouldn’t it?, Maybe pull is ok for this instance and there won’t be much if any difference in cpu temps.

If using pull on the radiator, what do you think of this airflow setup? The cooler will only fit as pic’d.
No 5.25 bay and a filtered grill there.

I have a couple new S12B Flex from a while back and thinking I’ll paint and use those.
I could just get another Helix 140 to go on top next to the one already on the rad, + rear A12 PWM, + front 200mm.

Here’s the bottom to the cooler:

If I leave it as push, what about pushing from top and bottom, and out the front and back?
View attachment 177777
Can something like CM Mega Flow 200 mount as exhaust behind a front panel?

The S12B’s have speed adapters.
Can fan speed be adjusted in BIOS or Fan Expert 3, on a 3 or 4 pin fan, and not use adapters?

Thoughts?
Edit: 2x120 will fit behind the tray but I'd rather not go there if I can help it.

Voltage-controlled fans can be adjusted by Speed Fan (don't ask me how, but it is done) and in BIOS -- IF your board is set up for it. For 140mm rads, best fan out is a Noctua A14 PWM. TR may produce a square frame TY14x, but don't hold your breath.

I always cut out my rear grills and allow air to flow out naturally. See here.

Yes, I saw that already.
Don't know what you mean by Tr though...

TR = Thermalright
Ah
TR may produce a square frame TY-!$x,
Sorry, don't know what square frame I'm looking for.
All the square fans will be Noctua, and the 2 Helix 140's I've decided to go with for the top. If I'm not happy with the Helix, then I'm out $15.
It's case ready for a round 200mm behind the front panel. Or a 120 or 140 can go inside or outside front.

I messed up. The fans are the TY-14x line, PWM with the equivalent of FDB. Fine fans . . . when they are available with square frames.

A12, matching top 140, and 200mm will be here today.
I'll set it up like the top photo and see what temps I get.
