The ENDORFY Fortis 5 ARGB is our favorite air cooler. It's super quiet, so quiet in fact that you’ll barely hear your PC at all. Plus, it can fit in even the smallest of cases and looks awesome thanks to the ARGB backlight.
The ENDORFY Fortis 5 ARGB is 15.9 cm tall, enough to easily keep CPU
temperatures cool. It's supported by the Fluctus 140 PWM fan, which is attached to a densely finned asymmetrical heatsink with unidirectional airflow. Ultraquiet and highly efficient, you can’t go wrong with a cooler like this. Mounting the ENDORFY Fortis 5 ARGB is no rocket science – you can conveniently install it on today’s most popular sockets. It will take you just a few minutes.

The ice age is coming
We often say that the Fortis 5 ARGB is one of the quietest coolers in its class. It has been rigorously tested through hours of podcast recordings, chatting with friends, as well as streaming. Thanks to this we can definitely say: it is quiet.
Even when doing all the above at the same time!
A constant stream of airflow is supplied by the award-winning Fluctus 140 PWM fan, which also includes an optional semi-passive mode. The blades have been shaped in such a way as to blow as much air as possible through the densely arranged heatsink fins. The fan reduces temperatures to such an extreme degree that we have a theory: if our plans to create the Fluctus 1400m fan ever come to fruition, another ice age might be unleashed on the world. Don’t worry though, you’re safe. For now.
Each blade has a wavy edge, which further reduces fan noise (psychoacoustic optimizations used in Fluctus fans are patent pending).
