Personally, I am curious if anyone is running a corsair sp120 quiet edition on the radiator. I am unsure if that would be sufficient (rad as intake) or if I should rather look at the sp120 HPE with the 7v adapter. Any experience outta there?

Not sure if it's worth anything yo you, but I'm going to use the Noiseblocker Eloop on the radiator. As far as I've heard/read it's noise/performance ratio is one of the best (just behind the Scythe GT AP15) if you use the fan in push orientation.

Take a look at the be quiet! Silent Wings 3 High Speed fans, available in a 4-pin PWM version or 3-pin version. Excellent radiator fans with very high air pressure and relatively low noise levels. Best I have found so far, and the readings are real, not exaggerated like some. Like all fans, the air pressure is in push, not pull.
 

• fan speed max: 2,200 rpm - (Corsair SP120 is 2,350)
• air flow max: 73.3cfm - (Corsair SP120 is 62.74)
• air pressure max: 3.37mm/H2O - (Corsair SP120 is 3.1)
• noise level max: 28.6dB(A) - (Corsair SP120 is 35)

 
I also use their standard Silent Wings 3 case fans for my case, which are almost silent, but obviously are much lower pressure (1.79 mm/H2O) and lower air flow (50.5 cfm), max 16.4dB(A) at full power, at 1,450 rpm. Not intended for use as radiator fans.
 
They are fairly expensive, but you get what you pay for.
 
 
 
 
 

As a follow-up:
 
Running with a Corsair sp120 with 7v-adapter: The fan itself is actually not audible, contrary to the one on the GPU, even tho I expect this to lessen once the initial phase of the bearing-adjustment is over. Temp-max is 47° in a Corsair Air 540 as intake, inbetween two AF120 quiet edition during a session of BF1 on ultra. The card clocks in at 2012MHz on stock settings.

I received my 1080 Hybrid early last month, finally registered on the 19th.
I was sceptical after finding out it was from factory 25 with a number lower than 700.
Wrapping came off without a problem and the card's been running well. So far, so good.
Boosts to 1983 ish without touching anything. Temps in the low 50's (ambient 20-22C) C with the default fan set to exhaust.
 
The reason I'm posting - I want to move my hardware into a Corsair Air 740 case.
How critical is it to not put the radiator below the GPU?
I figured either the lowest front slot or one of the bottom case slots would fit the radiator with 2x Noctua NF-F12s in push pull as intake.
