Coolermaster Hyper 612S CPU Cooler

Cooler Master known for its coolers, chassis, fans, power supplies and accessories, decided to send us a sample of  the “ultimate CPU silent cooling solution,” Hyper 612S. From the moment I took the box with the cooler into my hands I knew that this was a serious product based on its size and weight.

Hyper 612S comes packaged into quite a big box without any windows, and is the biggest CPU cooler packaging I’ve ever had in my hands! That is always a good sign.

The cardboard box art is done with a purple and white pattern. There are a couple of big pictures of the product, dimensioned drawings along with the main futures, specifications and big title with logo.

Opening the box, we see that the cooler is very well protected with protective foam.
Right at the top we found two user manuals and the small white accessories box tucked in a foam slot.
