When I decided to upgrade my CPU cooler, the Thermalright Peerless Assassin 120 caught my attention. After spending some time researching and testing it, I want to share my experience and guide you through the important aspects to consider before making your purchase.

Design and Build Quality

Also, I verified RAM clearance since the heat pipes can sometimes interfere with taller memory modules. In my setup, everything fit perfectly, but it’s something to keep in mind depending on your build.
