SilenX 120HA5We will be taking a closer look at the EFZ-120HA5 which is aimed at what SilenX is known for. Quiet operation. It also has two other characteristics that is a must have for many of us and that is great performance and an affordable price tag. The 120HA5 is of the tower design and weighs in at 648 grams. And according to SilenX, it only takes ten minutes to install. So, we are guessing it is a pretty simple process. We will see.

Introduction to the SilenX Effizio EFZ-120HA5 Performance CPU Cooler

Today, we will be taking a look at a new cooler from a company we have yet to do a review for. The company is not new and has been around for some time, we just haven’t been lucky enough to evaluate one of their products until now. SilenX is a leader in silent computing. Their fans have been used by many determined to keep their system at a very low noise level.

SilenX also dibble in heat sinks as well. The current have about ten of them within their Effizio line. Each of the ten is different from one another. There is fan size, structure type or weight distinctions between each. We really suggest taking a look at their site just to see how different each one is.

SilenX’s take the EFX-120HA5

The ideal cooler for, well, just about anybody, the EFZ-120HA5 is the perfect complement to any system. Great performance, low noise and with a very affordable price tag, this cooler will work with the most powerful processors on the market today, including those with the new LGA2011 mounting system. Rest assured, there are no other heat sinks on the market that provide this level of performance at the same price point, especially when you factor in low noise characteristics. The EFZ-120HA5 utilizes three 6mm heat pipes that directly contact the CPU and are intertwined to provide six effective heat pipes worth of thermal dissipation. A universal mounting bracket supports the widest range of current AMD and Intel sockets, including the latest multi-core Phenom and i3/i5/i7 processors.

We've included an Effizio 120mm fan with 3rd generation fluid dynamic bearings for years of reliable performance and no need to purchase any additional fans, though you have the option of adding a second fan for more performance. The installation process is easy with a typical install time of under 10 minutes, and does not require any specialized tools, just a simple screwdriver is all that's needed. Each Effizio heat sink comes with a three year warranty from the date of purchase and as always, you can be sure of getting the service should you need it.

Closer look

There are a few aspects that one must know about coolers before purchasing one. Ten times out of ten they are listed on the box somewhere, but we will take this time to summarize them for you now. First of all, the Effizio cooler according to SilenX capable of cooling various CPU socket processors including the AMD AM3 and Intel LGA2011, meaning all necessary mounting equipment is included. SilenX aimed the cooler at being a stock cooler replacement as well as silent operation. The cooler weighs a mere 648 grams which is a lightweight compared too many other coolers on the market.

The stance of the cooler is the typical and well perfected tower-style. A majority of cooler is comprised of a series of anodized aluminum fins. If you glance over the cooler from the top down you will see how each layer of aluminum’s edge overlaps the one underneath it.

Three 6mm in diameter copper heat pipes are used to support the tower of aluminum fins as well as construct the base of the cooler. Like all tower coolers the heat pipes begin and end at the top of the cooler giving the appearance of six heat pipes instead of three.

The base of the cooler is comprised of the copper heat pipes as well as aluminum. The cooler uses direct heat pipe technology to make it more efficient.

The cooler uses a Effizio class silent 120mm for cooling the fins after they have done their job. The unit is a fluid dynamic bearing model that by SilenX’s word is less than 1600 RPM and has a noise level of 8- to 24 dBA. The amount of air it pushes is between 32 and 86 CFM. Giving the range of the last two characteristics you can safely assume the fan is PWM controlled, but you would be incorrect. The SilenX is not PW controlled. It is just a low spinning model.

Mounting

For demonstration purposes and also because we were reviewing our first X79 motherboard, we use it to show the mounting of the cooler. But the actually testing was done on our ASUS P67 Deluxe.

Testing Methodology

For our testing we will be using the following procedures and parameters to acquire the necessary data:

  1. Thermal compound used is Arctic Silver 5
  2. Idle temperatures are recorded after the system has been allowed to idle for thirty minutes from the point Windows has finished loading.
  3. Load temperatures are recorded by running OCCT for twenty minutes on all available threads.
  4. Real Temp is used for the recording of all temperature sensor reading.
  5. PWM function is disabled via BIOS to allow the fans to run at full speed.
  6. CPU model and overclock speed used for testing are outlined below in "Test Hardware".
  7. Each cooler is first tested with one fan supplied from the manufacturer.
  8. Each cooler is then tested again with a second fan attached if provided by the manufacturer.
  9. Lastly, the cooler is tested a third time using a neutral set of fans to make all things equal.
  10. Neutral fans used are Aerocool Sharks 120mm, 1500RPM, 82.6 CFM, 26.5 dBA.

Test Hardware:
Motherboard: ASUS P67 Deluxe B3
Processor: Intel Core i5 2500K @ 4.5GHz w/ 1.3 voltages
Ram: Crucial 2133 4GB Dual Channel (9-9-9-24)
Video Card: ASUS Radeon HD 5870
HDD: Hitachi 1TB
Power: Thermaltake Tough Power XT 850 (Sponsored by Thermaltake)

Cooling: SilenX Effizio EFZ-120HA5

Results


Conclusion

The SilenX Effizio EFZ-120HA5 is a real solid performer and very capable of cooling all generation processors. And it does this using a really quiet fan. So, quiet that you will have to place your ear almost next to the cooler to hear it. SilenX lived up to its name with this cooler. This cooler is for those looking to achieve muteness from their machine.

The cooler’s thermal performance was just shy of some of the other coolers we have tested. But one has to remember these other coolers come with larger CFM fans. Making their cooling potential greater. And many of us would take the difference in performance when it comes to the noise levels we see from some coolers. Granted, the SilenX did perform really well when we added our dual fan setup, showing faster fans makes a difference with this cooler.

All in all for about $30-$35, you could have a very good cooler. Much better than the stock cooler and less noise than other after-market coolers.
