The CPU cooler is designed to keep heat away from CPU, so its importance can be imagined. Installing a CPU cooler isn't difficult, especially a downward-flowing cooler, but for a tower-side-flowing CPU cooler, it's said to need right fan orientation for better heat dissipation. Which direction is CPU cooler fan facing? Let me share a diagram of installation direction of a side-blown CPU cooler tower fan.

As a general rule, we don't need to care about direction of fan for underflow radiators and supply pressure.
