Have not put it under stress test though, I'm happy! But thanks for the tip!
Having the exhaust fan and cooler center fan both on cooler towers in pull / pull will (should)
still flow air out of case as well as your present setup with one fan push fan on 2nd tower and rear exhaust. That hypothesis is based on experiences of several of us. As your cooler is now, only one tower is getting full use of one fan. Airflow to fan in middle is now all coming through front tower. Add that at low speed fans have much less abilty to overcome resistance which results in less airflow and the resistance being almost doubled with 2 towers means even less airflow. With exhaust fan so close to cooler, moving it from case exhaust vent to back of cooler should make no difference in case airflow, but will improve the flow through coolers 2nd tower. Moving the middle fan from being clipped to back tower to front tower (still in middle) will improve airflow through front tower. I say should in a couple of places because airflow is very hard to predict because there are so many variables to consider. For example if your case has fans balanced so they are pulling slightly more air into case then out, moving the exhaust fan to cooler will definitely work, but if case is not .. We want intake and exhaust fans to be near perfect match to optimize flow. This way there is no waste. Ina perfect world this wil also keep dust from lieaking in thorough vents with no fan on them or other holes in the case. But this is not a perfect world, so a little more intake insures there is just a little air leaking out vents whit no fans and other holes. Al of this is also a good reason for case fans to be automatically controlled the same as CPU and GPU fan because this allows case fans to increase and decrease in speed and airflow at the same time as component fans. This also helps keep airflow flowing in the same paths through the case.
