problems with H100i GTX + airflow questions

[Bl00dgod]

i hope this is the correct topic, maybe it has to be moved

Case: beQuiet SilentBase 600 ( i removed the bequiet purewings )
actual rig in signature

TOP -> H100i GTX "stock" ( i think there was a dustfilter on top too )
FRONT -> Noctua NF A14 "FLX" ca 1200 RPM @ 18 dB + dustfilter
BACK -> Noctua NF F12 "FLX" ca 1200 RPM @ 19 dB

bottom -> PSU exhaust + dustfilter
fan placement

 

 

rig

( needs to be turned around -> 90° )

 

ambient temperatures are 10-15°C day, night open window 1m on the right beside the pc outside air -2°C actually
idle temps GPU <30°C load sometimes up to 50-60°C with fans spinning 50-60%
idle temps CPU ca 40°C load ca 60-65°C devils canyon OC runs @ 4,6ghz (didnt try to get it higher)

1. are the vents good enough for the top? because it feels like only 1 fan could exhaust and the other blows against the case
2. the only thing i can hear are the aio pump + fans
3. is there a chance to reduce the voltage for the pump so it wont run 100% when the cpu only has 50-60°C
4. should i change the fan setup in any way? back to intake or something like that?

the AIO fans are connected to the pump but i'll swap it to mainboard connectors

possible solution for 2.
i was thinking about 2 linus-style Noctua NF F12 "PWM": 22,4dB max 1500RPM static pressure 2,61mmH2O "air rate" 93,4m³/h
instead of the standard Corsair H100i GTX :37,7dB max 2500RPM static pressure 4,65 mmH2O "air rate" 70,69m³/h
or would you suggest some other "silent" pressure fans

sorry for the bad quality i took the pics with my old wooden sony xperia typo
newer will be made with oneplus2

if necesary i could take some more pictures of the complete setup etc later when i'm home

I personally use the SP120 Quiet Edition fans from Corsair as they can be run off the pumps headers without cooking it.

anyone else some suggestions?

In corsair link there should be an option to turn the pump down to a quiet mode and then all you'll hear are the fans.  Phanteks PH-F120MP should do well over the stock Corsair fans or the Noctua, if you so desire.  The vents up top should be good enough for exhausting the air, but you could always try using it as a way to pull air in to the case and out the back.  That might change the temps a little, may be even in favor.

current negative pressure

rear, psu, aio, =4 fans push out

front 2 nfa 14 =2 fans pull in

with a top intake i would change the setup to positive pressure

 4 fans intake

rear fan and psu exhaust

 

nice idea, i'm going to try this within the next few days and order some noctua's... or try ghetto mounting my 2 140mm noctuas i have around somewhere to the 240mm rad

 

i could also try to fit an 120 or 140mm fan between psu and HDD cage
