Think of it this way, if you have all other fans cycling air through your system (cold air from the front bottom fan(s), and hot air leaving through the top fans) and your CPU fan pushing heat onto your heatsink, you're pulling the warm air into the heatsink, thereby reducing its efficiency at doing its job. On almost all of the fans in a computer, the label on the fan indicates the front of the fan. Should my computer fans be sucking or blowing?

How do you think about the answers? zero-point energy and the quantum number n of the quantum harmonic oscillator. The only time I got any improvement with the fan on the other side pulling air through, was when the same fan was ducted direct to the outside of the case, so the heat from the cpu was direct to the outside via that fan. kitguru.net/components/cooling/dominic-moass/…, tomshardware.com/forum/335129-28-push-pull-tested, Podcast 302: Programming in PowerPoint can teach you a few things, Optimal Fan Placement and Direction for Air-Cooling a Computer.

From what your saying your flow arrangement isnt to the front, so like you I do not see any reason to send it towards the front, to just fight the flow and eventually head to the back anyway, turbulance has value :-) but exhausting the worst heat most directally out of the case is going to make the whole case cooler. Induced cooling- hot air is drawn from over the surface of the heat sink to allow fresh cool air to fill the space which enables-cooling..

If your PC case has a vent on the bottom for your PSU intake fan, and you’ve installed the PSU with the fan facing downwards, you should take some extra steps to help ensure proper airflow. It doesn't matter what side of the heatsink the fan is on, as long as the fan is blowing the hot air out the back/top of the case. Your CLC at 55% is making a little louder than a top tier cooler at 100% .. and most of us on air rarely run above about 70% (1000-1100rpm @100% CPU load @ 60-65c depending on CPU, overclock, case fans & cooler being used). In order to have the right fit, your replacement CPU fan will require to have the same number of pins as your current CPU fan. The heatsink dissipates the heat produced by the CPU. When it pulls the air out of the case it creates suction so all of the vents in the front and sides bring in fresh air evenly and more gently so less dust gets sucked up. Is it my fitness level or my single-speed bicycle? The case should have vents on the top. On the other hand, blowing the air increases its pressure, thus increasing the number of air molecules and their ability to carry away heat energy. Air Should Flow from Front-to-Back, and Bottom-to-Top When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top. You don't want to blow dust from the outside into the case. If adding an outside fan helps that much, there are a couple things you can do to likely help reduce your CPU temps. Airflow through the case is important, so yes, it matters. Didn't the arrow indicate the direction the air gets pushed to? You should also heed the placement of the fans.
