EnzoTech Ultra-X CPU Cooler


Product: EnzoTech Ultra-X CPU Cooler
Provided By: EnzoTech
Price: ~MSRP N/A



Over the past year, we've seen a lot of heatsinks from Zalman, Gigabyte, Noctua and most recently, Arctic Cooling.  Up until a few weeks ago, I'd never heard of EnzoTech, but apparently they have been making coolers since 1982.  Today we are looking at the EnzoTech Ultra-X CPU cooler that is built for Socket 775 Intel CPU's as well as AMD Socket AM2/754/939/940 processors.  EnzoTech is new to the North American market as you can't yet find their coolers anywhere.  After taking a look at this product on the following pages, you may just have to write an email to your favorite computer store and get them to stock these coolers.  Read on to find out if 25 years of cooling experience is enough to make a killer cooler.

First Look:

The EnzoTech Ultra-X comes bundled with everything you need to get up and running on every popular platform available today.  While I know that some of you are still looking for a good Socket A or Pentium 478 cooler, the truth is - you have old gear.  If you want a new cooler, get new gear.


The bundle consists of a retention frame back plate for AMD platforms if you don't have one already.  If you have a current retention frame already on your Athlon motherboard, you won't even need to remove the motherboard to install this cooler.  There is also a backplate and mounting hardware for Intel LGA775 platforms as well as a bag of screws, washers, and more.  EnzoTech has also included a PCI slot mounted fan controller, a installation manual and some Arctic Silver 5.  Not a bad bundle for any cooler.

Below are some pictures of this cooler from various angles so that you can get a better idea of its size and design.

Closer Look:

The bottom of the Ultra-X shows us a couple of things.  First off, you can see how fine and close the fins are and how they interact with the heatpipes.  In the second picture below you can also see just how fantastic the finish on the HSF base really is.  EnzoTech claims that it is a mirror finish and I can't argue with them.  Not only is the HSF base smooth it also appears to be very flat.

On the next page we'll cover installation, the test setup and jump into testing.


The Ultra-X cooler can be installed in a matter of minutes on an Athlon based system, and that is what we did.  Our Core 2 Duo system is currently tied up with another project, so we dropped the Ultra-X on our Athlon 4200+ in less than 5 minutes.  Most of the time was spent cleaning up the old thermal paste and applying new paste to the CPU core.  Below are a couple pictures of this cooler installed on the CPU as well as the rear PCI slot fan controller.

The Athlon 64 install uses a clip that can be a little difficult to install if your case is crowded.  We never had any issues in a cheap generic case that we've got on the bench and the heatpipes cleared the memory modules with about 1mm to spare.  With our memory in the slot closest to the CPU socket, removing it will be a problem with the cooler installed.  We cannot fault the cooler too much though as it could be more of a motherboard specific problem.


Test Setup & Info:

Below are the test system specs for the Ultra-X cooler review.


When testing CPU coolers, there are many factors that can cause fluctuation in performance numbers.  When we test coolers, we generally mount the cooler at least twice in order to make sure that it makes good contact with the CPU.  An air bubble can cause a temperature increase that does not reflect the quality of the cooler.  In the benchmarks below, we used the included thermal paste with each cooler.  For the Zalman CNPS9500 AM2, this was the standard white thermal compound, and for the Ultra-X from EnzoTech, we used Arctic Silver 5.  As we have seen in the past, thermal compound makes a difference in a coolers performance, but we are using different thermal compounds to show you how these two coolers compare out-of-the-box.

We tested the coolers at stock speed (2.2GHz) as well as overclocked (2.64GHz) with the voltage bumped up to generate more heat.  The room temperature was kept between 20-21C at all times during testing.  We tested these coolers at their lowest fan speed setting as well as at their highest fan speed setting.  Both coolers are virtually silent at low speed, and do make a fair bit of noise at high speed.  The Ultra-X is the quieter of the two when turned up to the maximum.

On the last page, we'll test out this cooler and see how it stacks up.




The EnzoTech Ultra-X looks very similar to a Thermaltake Big Typhoon cooler, and while the Big Typhoon performed quite well, it was bested by the Zalman CNPS9500 series.  With that in mind, I didn't expect anything too fabulous out of the Ultra-X, but as you can see in the charts below, I was mistaken.

In every scenario and in every situation, the Ultra-X beats down the Zalman CNPS9500 out-of-the-box.  As stated previously, the thermal compound may have something to do with this, but we used what came with each cooler to represent the average consumers install.  I was very impressed with the noise, performance and overall quality of the Ultra-X cooler.  In many situations, it beat out the CNPS9500 by as much as 5C!



I have long been a Zalman HSF user on my personal computer as well as BCCHardware's test machines.  Zalman makes very good units that offer great performance and low noise.  They have met their match today with the EnzoTech Ultra-X cooler however.  This cooler is large and may have some issues fitting in smaller cases, but in exchange for its bulk it offers good - no, great performance and does it quietly.  If you are looking for a new cooler that will take you to the next level in terms of overclocking, good looks and sheer performance, you owe it to yourself to find an Ultra-X from EnzoTech.  We were very impressed and I know you won't be disappointed.
