I'm planning a build utilizing the Nemesis GTR 420, on top and in front on the 7000D Airflow case, so far my leading candidates are the,
iCUE SP140 RGB ELITE Performance
&
HD140 RGB LED High Performance 140mm PWM fans, however my main focus is high end gaming and flight simulators but with a bit of flare. The HDs speak for themselves as the highest static pressure fans available, however I'm not really digging the push button thing and it has 12 LEDs which is great, also SPs are very close behind in static pressure and performance but still have the 8 LEDs which for me would be plenty. I'd be interested in hearing form those more knowledgeable than I on which would benefit me the most overall given my PC focus, I'm thinking that the lower static pressure with the 55mm GTRs may work better overall, thanks and love the forums here and glad to be apart of it all.
