MSI Core Frozr L CPU Cooler Review: Frozr Goes Vertical

A Closer Look at the MSI CORE Frozr L »

MSI Core Frozr LMSI’s Core Frozr L may be the motherboard company’s first CPU cooler product released but this is not in any way an amateur attempt. Frozr coolers have been used on MSI’s graphics cards for almost a decade now, with their Twin Frozr thermal design currently in its sixth generation used on the latest NVIDIA 10-series graphics cards. The MSI Core Frozr L is simply a vertical adoption for the CPU of what MSI has been doing horizontally to GPUs for the past few years.

Aside from enjoying plenty of success with their motherboard and video card sales lately, MSI also successfully branched out to offering pre-assembled gaming systems in addition to their gaming laptops. In the course of designing and building these gaming systems, MSI has seen firsthand what kind of CPU cooling requirements are needed inside a high-performance gaming desktop. Naturally, the Core Frozr L came about from this knowledge, with gamer aesthetic and gamer cooling requirements in mind.
