Last week I installed a Corsair H110 in my Cosmos2 case. I installed it up top in the case for the rad and the fans could not be installed on the red for mb clearance. The 2 Noctua 140 fans I put on were installed on top of the case in the space where top case fans go in pull config.After hooking everything up and I rev the fans to top speed 1500 rpm,it seems the airflow when I put my hand on top it feels like there is not a lot of air moving.Even if I put a lit smoke on top of the screen above the fans the smoke seems to barely move.Is this because of the fans are in pull compared to push. I had a swiftech H220 on before the pump went in my cosmos2 in push/pull,as exhaust and I could feel a ton of air moving but with 4 fans on the the rad though. Anyway,if anyone has any ideas I would greatly appreciate it.
