Which direction is CPU cooler fan facing? Installation diagram for a CPU cooler fan that blows over side of tower
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.
Only when installing a side-flow CPU tower cooler, you need to pay attention to direction of CPU cooler fan. memory as shown in picture below:
CPU cooler fan direction
The side of case blows CPU heatsink fan around memory to push hot air directly out of case.
The above is a diagram of direction of installation of a common fan heatsink CPU with tower side airflow. Hope this article helps everyone.
