I still used the rubber inserts on both sides of the fans, but aside from those, they are directly mounted. The top ones however, are not. They are mounted on drop-in rad plate.
I have 6 in push and pull on my Airplex, mounted on the ceiling of my case. The ones on top have always worked fine, but the ones on the bottom have been sporadic. Sometimes 1-2 will suddenly stop spinning, or even just spin at a lower RPM than the others, and such. But once I hit a certain voltage on the top fans, the bottom ones instantly start spinning. Im not sure if its because of the air flow of the upper fans, but it seems rather quick and aggressive in their speed up to be from the above air flow.'
Im considering just removing the bottom 3 fans, and replacing them with the BlackSilentPro 1400rpm fans. and then using those 3 Eloops for the front and back intakes of my case, as I dont have any right now.
