Specifications, Availability and Pricing


The EFZ-120HA4 is fashioned like a typical tower style cooler. At the base you will find an aluminum plate holding five 8mm heatpipes that are milled flat and make direct contact with the CPU. Heat then has two options; travel into the Aluminum pre-cooler on the top of the base or it can continue up the five heatpipes on either side. It is then up to the forty-six, 0.45mm thick, aluminum pressed on fins to absorb the heat from the pipes and allow the EFZ-12025-HSF fan to do its job.

Speaking of fans, I was sent two different fans to test the EFZ-120HA4. Of course, there is the EFZ-12025-HSF that comes in the box. This fan can operate in the range of 5V to 12V, and offers up to 102CFM at less than 18dBA noise levels. They also had sent me an IXP-74-09 fan for testing. This fan offers the user up to 38CFM at around 9 dBA, but operates between 8V and 14V. From what I have seen so far, with the fan included in the box, I don't really see a need to drop down to 9 dBA, but to some it might just matter. For me the EFZ-12025HSF in conjunction with a fan controller can offer the same low end as the second fan they included for my testing.

This SilenX cooler is pretty fresh on the market, but that doesn't mean it isn't readily available. Searching via Google shows a couple locations in the U.S. where it can be purchased. Pricing will average around the $40 USD mark; well below my $50 cutoff. With that said, the SilenX boasts extreme silence, and not at an extreme price tag. Price and silence out of the way, it is definitely time to get a closer look at the EFZ-120HA4 and see how well the efficiency of this cooler holds up to the rest.

Jumping into computers for just the aspect of gaming is how it all started for me. After a solid year of gaming, I caught the overclocking bug. With overclocking comes the need for better cooling, and I have had both air and water setups to tinker with. With a few years of abusing computer parts, I looked for something new. I then decided to take my chances and try to get a review job with a online site. As an avid overclocker, I am always looking for the next leg up in RAM, cooling, as well as peripherals technology.
