Testing and Final Thoughts


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.
