SilenX Effizio EFZ-120HA5 CPU Cooler Review

SilenX is a company of humble beginnings, with a group of engineering students who craved for silence from their computers. Starting in 1995 these students began to test and develop cooling systems that became integrated into recording studios and sound labs, due to their impressive low noise performance.

Fast forward 16 years, and SilenX is now providing efficient low decibel cooling systems for OEM usage and also computer users of every background.

Today finds us testing one of the new coolers from their popular Effizio line, the EFZ-120HA5 heatsink. With our recently decommissioned test bench being converted to an air cooled configuration, the timing couldn’t have been better!


“Outside the Box” thinking, in terms of air cooling performance and noise levels, is what has led SilenX to the position they are today.  Lets see what they have to offer with this new cooler.

The box is sturdy and attractive, giving a glimpse of the heatsink inside.

The rear of the box lists the advantages and benefits of the heatsink, including the types of sockets and systems that this cooler will work with. There is quite a compatibility list, with Intel Sockets 775, 1155, 1166, 1355, 1366, and 2011 covered. On the AMD side there is support for Sockets 754, 939, 940, AM2, AM2+, and AM3. With regards to compatibility, you can slap this on just about anything.

A quick click will bring all photos up to size.

On the inside of the box we can see that the unit is well packaged, with the components in separate plastic trays.
