The SilenX EFZ-120HA5 is a tower-style CPU cooler, with three copper heatpipes and a 120 mm fan. Let’s test it!

It is hard to say what the real brand of this cooler is, since the brand on the face of the box of the cooler (and on the cooler fins) is ”PCCOOLER,“ but the EFZ-120HA5 is present only at the SilenX website, and does not exist in the PCCOOLER website. There is no explanation as to what the connection is between those two brands.

The cooler comes in a nice box with a transparent window that allows you to see the cooler heatsink, as seen in Figure 1.
