PWM splitter from CPU
I've got to say this is one of the best setups I've ever used. I've got another PWM splitter in case I need it for later, but for now I'm entirely happy.
On full blast and on idle, this is almost perfectly balanced - no air is drawn in OR vented from the gaping grille at the top of the machine, and it keeps the CPU within very respectable temp ranges. Akasa fans are far, far better than I expected at this price point and I'm very, very content with them. I always considered Akasa to be a fairly mediocre budget choice, but these fans are really, really good. In fact, unless I'm imagining things, I think the thermal profile of the Venom compares favourably to my Silent Typhoon 1850rpm, and it sure as heck does a better job of shoving air through my TRUE.
Anyway, I'm a PWM splitter convert and an Akasa convert. Thanks to all who contributed.
Only change I may make in future is to replace the front 3 Apaches with Venoms, but that's for another day.
